2019-Apr-07 UT 10:40-10:41 Ill=4% Aristarchus observed by Hobdell on 1981-6-5

     On 1981 Jun 05 at UT 01:08-02:04 B. Hobdell (St Peterburg, FL, USA, 
     10" and 4" reflectors, seeing II) found Aristarchus bright at the 
     following times: 01:08, 01:10 and 01:15, and furthermore had yellow in 
     its south east corner. Some cloud intervened, but upon clearing the 
     crater was about 4th magnitude. At 01:45UT two very bright, long 
     duration, yellow glows were seen in the south east. At 01:58UT two 
     flashes seen in this location and at 01:59UT a white flash, then at 
     02:01UT a long blue flash, and subsequently other ones. The Earthshine

2019-Apr-08 UT 10:41-11:42 Ill=9% Aristarchus observed by Celis on 1969-11-12

     On 1969 Nov 12/13 at UT23:30-01:30 Celis et al. (Valparaiso, Chile) - 
     one observer saw Aristarchus with bluish scintillations occuring in an 
     irregular way - Apollo 12 watch. The Cameron 1978 catalog ID=1207 and

2019-Apr-08 UT 11:13-11:44 Ill=10% Earthshine: sporadic meteors

2019-Apr-09 UT 11:14-12:09 Ill=16% Unknown observed by Unknown_Observer on 1880-11-6

     On 1880 Nov 06 at UT 20:00 an unknown observer observed a TLP at an 
     unknown location on the Moon. The Cameron catalog has an entry for this 
     date and time but does not specify the location, the observer or what 
     was seen. The Cameron 1978 catalog ID=218 and the weight=0. The 
     ALPO/BAA weight=1.


2019-Apr-09 UT 11:31-12:44 Ill=17% Aristarchus observed by Hobdell on 1981-6-7

     On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Petersberg, FL, USA, 
     10" and 4" reflectors, seeing=I) at 02:30UT saw a flash from 
     Aristarchus and another one from Schroter's valley. By 02:45UT 
     Aristarchus was starting to be difficult to see and had occasionally a 
     bluish cast. By 03:00UT the crater could only barely be seen. This was 
     odd because visibility on the Earthlit side was really rather good. The 
     Cameron 2006 catalog ID=143 and weight=0. The ALPO/BAA weight=1.


2019-Apr-09 UT 11:31-12:44 Ill=17% Copernicus observed by Hobdell on 1981-6-7

     On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Peterberg, FL, USA, 10 
     and 4" reflectors, seeing=1) saw Copernicus to be very bright in blue. 
     Clarty of Earthsine was exceptional tonight. The Cameron 2006 catalog 
     ID=143 and weight=0. The ALPO/BAA weight=1.


2019-Apr-09 UT 12:40-12:44 Ill=17% Mutus_F observed by Spellman_R on 2005-1-15

     On 2005 Jan 15 at UT 01:25 R. Spellman (Los Angeles, CA, USA, 8" 
     reflector) observed 4 bright points of light on the crater Mutus F? - 
     see Rukl Atlas page 175, chart 74. If his identification of the crater 
     was correct then he could see no structures in the crater that would 
     yield this effect. It could well be that the 4 bright points are just 4 
     high peaks on the rim catching the first rays of the Sun. The ALPO/BAA 
     weight=1.


2019-Apr-09 UT 12:41-12:44 Ill=17% Mare_Crisium observed by Thomas on 1915-12-11

     North shore of Mare Crisium 1915 Dec 11 UT 06:00? Observed by 
     Thomas (Glenorchy, Tasmania) "star-like pt. on N. shore of 
     mare. (Eimmart?) Particularly bright spot. Tho't it was 
     sunlight from rim of sm. crater." NASA catalog weight=0 NASA

     On 1969 Nov 11/12 at UT23:30-01:00 Mitchell, Celis and Marti (Paso 
     Hondo, Chile, 10" refractor, x96, 4" refractor, x80, 3" refractor, x60, 
     seeing = excellent) observed Aristarchus with a blue centre and 
     irregular form, alternating with normal aspects. Some opacity 
     (independent confirmation?) - Apollo 12 watch. The Cameron 1978 catalog 
     ID=1208 and weight=3. The ALPO/BAA weight=3.


2019-Apr-10 UT 10:54-12:04 Ill=25% Aristarchus observed by Hobdell on 1981-6-8

     On 1981 Jun 08 at UT01:48-02:45 B. Hobdell (St Petersberg, FL, USA, 10 
     and 4" reflectors) could hardly see Aristarchus crater, however at 
     01:48UT it brightened in blue for about 3 minutes. Then at 02:20UT 
     there was a bright flash, and by 02:25UT the crater was very bright, 
     but by 02:45UT it was no longer visible. Cameron 2006 catalog ID=144 
     and weight=0. The ALPO/BAA weight=1.


2019-Apr-10 UT 11:07-13:03 Ill=25% Aristarchus observed by Davis_H on 1988-11-14

     On 1988 Nov 14 at UT 17:25-18:30 H. Miles (St. Minver, 
     Cornwall, England, UK, 5"refractor? x60 and x120) found 
     Aristarchus to be a white ill-defined circular patch. At 
     17:45UT it was a lot brighter (Cameron comments that this 
     might have something to do with sky darkness). In contrast, 
     Copernicus was just seen as a white patch and the Jura 
     mountains could be seen (not as bright). Aristarchus grew 
     brighter over time and there was a bright point on the west 
     wall (seen at x60 and x120). Īt was fainter at 1854 & < At 
     1830. (Foley) said Earthshine cond. Superb with many regions 
     clearly seen, but Aris. was dull. (Cooks) in hazy condition 
     could not detect Aris." The Cameron 2006 catalog ID=338 and 
     weight=0. The ALPO weight=1.   


2019-Apr-10 UT 11:46-13:43 Ill=25% Moon observed by Hirst on 1879-10-20

     In 1879 Oct 20 UT 23:00 (Local time Oct 21 9AM) Hirst (Blue Mountains, 
     NSW, Australia) saw a large part of the Moon covered with a dark shadow 
     that was as dark as the Earth's shadow would have been if there had 
     been an eclipse. Cameron says that this is a confirmed observation. 
     Note that the Moon was just before first quarter. The Cameron 1978 
     catalog ID=215 and the weight=4. The ALPO/BAA weight=3.


2019-Apr-10 UT 12:32-13:45 Ill=26% Aristarchus observed by Foley_PW on 1980-4-20

     On 1980 Apr 20 at UT 19:25-23:43 P.W. Foley (Kent, UK, 10" reflector, 
     seeing II-III) found that Aristarchus was very bright in Earthshine 
     (also found on the photographs that he took), giving off a blue 
     "incadescence", the CED brightness reading was 5. Occasionally Foley 
     could see a star-like point in the south east corner. For comparison in 
     brightness he used highland terrain near to Grimaldi (CED=2). By 
     comparison, Buczynski and Lord, could not see Aristarchus. Earlier, 
     Geenwood saw the crater easily as a star-like point with a diffuse 
     exterior glow. Cameron says thyat this was confirmed by Buczynski and 
     Lord (?). At 20:35UT Amery decided that Aristarchus looked brighter 
     than normal. Pedler though described the crater as "small dim nebulous 
     blue or blue-green" that was invisible by 20:27UT. At 20:28-22:01 Blair 
     could not detect Aristarchus, nor could J-H Robinson at 20:40UT though 
     he did see it at 20:55UT as both diffuse and blue. Ricketts detected a 
     blow glow with irregularly spaced flashes of roughly 5-10 sec apart. 
     Cook's at Frimley, UK, saw no features in Earthshine. Cameron 2006 
     catalog ID=88 and weight=4. ALPO/BAA weight=2.


2019-Apr-10 UT 12:35-13:45 Ill=26% Aristarchus observed by Lagunas on 1969-11-15

     On 1969 Nov 15 at UT 02:20-03:20 Lagunas (Santiago, Chile, 10" 
     reflector) observed some brightenings in Aristarchus during the Apollo 
     12 watch. The Cameron 1978 catalog ID=1209 and weight=0. The ALPO/BAA 
     weight=1.


2019-Apr-10 UT 12:52-13:45 Ill=26% Piccolomini observed by Cook_MC on 1980-4-20

     On 1980 Apr 20 at UT 19:45-22:45 M.C.Cook (Frimley, UK) - colour 
     (probably spurious) seen on Piccolomini. Cameron 2006 catalog ID=88 and 
     weight=4. ALPO/BAA weight=1.


2019-Apr-10 UT 13:12-13:45 Ill=26% Copernicus observed by Cook_JD on 1980-4-20

     On 1980 Apr 20 at UT20:05-21:02 J.D. Cook (Frimley, UK, 12" reflector, 
     x60, seeing III-IV) at the start of this session found some bright 
     spots in the area of Copernicus, and at 21:02 detected some flashes in 
     this region. Cameron 2006 catalog ID=88 and weight=1. ALPO/BAA 
     weight=1.


2019-Apr-10 UT 13:34-13:45 Ill=26% Grimaldi observed by Price_M on 1980-4-20

     On 1980 Apr 20 at UT20:27 M.Price (Camberley, UK) saw a flash in the 
     Grimaldi-Aristarchus area. Cameron 2006 catalog TLP ID=88 and weight=4. 
     ALPO/BAA weight=2.


2019-Apr-10 UT 11:15-13:47 Ill=26% Earthshine: sporadic meteors

2019-Apr-11 UT 11:50-13:44 Ill=35% Apianus_D observed by Power_F on 2011-10-3

     Apianus D On 2011 Oct 03 UT 21:00-21:20 F. Power (Meath, 
     Ireland, 11" SCT) observed changing colours (blue, white, and 
     red) on the inner western rim of this crater. He changed 
     eyepieces and moved the scope around to look at dufferent parts 
     of the Moon, but nowhere else exhibited anything similar. As 
     another test he asked his wife to have a look without telling 
     her what he was seeing. She confirmed the same effect. 5 digital 
     camera images had been taken. Most of these were out of focus 
     and the first one was saturated, however one of them showed a 
     approximately 35 km long, by 11 km wide (at the north) lopsided 
     carrot shaped orange colour to the western rim of Apianus D. No 
     similar strong colour could be seen anywhere else on the image, 
     nor on the other 4 images. This TLP is being given an ALPO/BAA 
     weight of 1 as the Moon was low, but an image taken looks 
     interesting.


2019-Apr-11 UT 12:54-14:45 Ill=36% Censorinus observed by Holmes_D on 1988-11-15

     On 1988 Nov 15 UT 19:15 Holmes (Rockdale, UK, 215mm Newtonian) noticed 
     the Censorinus apron (just east of the crater and including the rim) 
     was fuzzy but the crater was clear - a sketch was provided. A BAA Lunar 
     Section observation.Cameron 2006 Catalog Extension ID=339 and weight=3.
     ALPO/BAA weight=2.


2019-Apr-11 UT 13:44-14:45 Ill=36% Torricelli_B observed by Braga_R on 2001-4-29

     On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any 
     filter, the brightness of the east wall of Torricelli B was halfway 
     Torricelli C (faintest) and Moltke (brightest). By insering a Wratten 
     25 red filter though, the crater was slightly more evident. However 
     using a blue Wratten 39A filter, the crater vanished completely, whilst 
     Toricelli C remained. The ALPO/BAA weight=3. 


2019-Apr-11 UT 11:16-14:47 Ill=37% Earthshine: sporadic meteors

2019-Apr-12 UT 10:45-14:31 Ill=46% Mons_Piton observed by Horne_P on 1983-3-21 *

     On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England, 
     UK, 11" reflector, x180 and x330) found that Mons Piton (totally 
     illuminated and brightest feature on the Moon - but no variability) was 
     brighter than Aristarchus (would have been if it had been in sunlight)
     and the mountain was contained within a circular illuminated patch. 
     "Brilliant white and no shadow. Size ~16km." There was no details 
     visible but the adjacent features had distinct shadows. Hutton was also 
     observing. Foley examined the photographs and believes that they are 
     inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and 
     detects Piton but it is not bright. However in a photograph taken by D. 
     Mansbrdige and 20:30UT the mountain is much brighter than any other 
     sunward facing slopses on the northern part of the Moon's terminator. 
     R. Mosley had been observing earlier at 18:10-19:40 and although 
     finding the mountain to be shining briliantly beyond the terminator, he 
     also comments that this is normal. Cameron though has seen the 
     photographs taken and thinks it might be a real TLP. The Cameron 2006 
     catalog ID=208 and weight=5. The ALPO/BAA weight=2.


2019-Apr-12 UT 10:45-11:32 Ill=46% Eimmart observed by Louderback_D on 1992-10-4

     On 1992 Oct 04 at UT 02:15-03:18 D. Louderback (South Bend, WA, USA, 
     3" refractor, x80) found that Eimmart crater was brighter in blue light 
     than in red light - however Cape Agarum, and Mare Crisium were too. The 
     Cameron 2006 catalog ID=454 and the weight=4. The AlPO/BAA weight=1.


2019-Apr-12 UT 10:45-11:32 Ill=46% Mare_Crisium observed by Louderback_D on 1992-10-4

     On 1992 Oct 04 at UT 02:15-03:18 D. Louderback (South Bend, WA, USA, 
     3" refractor, x80) found that Mare Crisium was brighter in blue light 
     than in red light - however Cape Agarum, and Eimmart were too. The 
     Cameron 2006 catalog ID=454 and the weight=4. The AlPO/BAA weight=1.


2019-Apr-12 UT 10:45-11:32 Ill=46% Mons_Piton observed by Louderback_D on 1992-10-4

     On 1992 Oct 04 at UT 02:15-03:18 D. Louderback (South Bend, WA, USA, 
     3" refractor, x80) found that Mons Piton was very bright and was equal 
     to Proclus (brightness of 9) in white light and 7.5 in violet, and 9.3 
     in red (Proclus was 9.2 in red). Īn blue both features = (9?). "points 
     on Piton affected were B, D, and C (S, W & N resp.) D in violet was 
     fuzzy - ill defined". The Cameron 2006 catalog ID=454 and the weight=4. 
     The AlPO/BAA weight=2.


2019-Apr-12 UT 10:45-11:32 Ill=46% Promontorium_Agarum observed by Louderback_D on 1992-10-4

     On 1992 Oct 04 at UT 02:15-03:18 D. Louderback (South Bend, WA, USA, 
     3" refractor, x80) found that Promontorium Agarum was brighter in blue 
     light than in red light - however Mare Crisium and Eimmart were too. 
     The Cameron 2006 catalog ID=454 and the weight=4. The AlPO/BAA 
     weight=1.


2019-Apr-12 UT 11:56-13:52 Ill=46% Censorinus observed by Cook_MC on 1988-11-16

     On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that a ray 
     north east of censorinus appeared to be very diffuse and this did not 
     change during the observation. This was odd because proclus ray 
     material remained clear. The apron material of Censorinus was diffuse 
     E-W and the northern part was dull, but not fuzzy. The Cameron 2006 
     catalog ID=340 and the weight=3. The ALPO/BAA weight=2.


2019-Apr-12 UT 11:56-13:52 Ill=46% Torricelli_B observed by Cook_MC on 1988-11-16

     On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that 
     Torricelli B changed in brightness (at times), but thinks that this was 
     due to atmospheric transparency. The Cameron 2006 catalog ID=340 and 
     the weight=3. The ALPO/BAA weight=1.


2019-Apr-12 UT 12:02-13:59 Ill=47% Ross_D observed by Harris on 1964-3-21

     Near Ross D (24E, 11N) 1964 Mar 21 UT 05:00-06:20 Observed by 
     Harris, Crow, Cross (Whittier, CA, USA) - negative confirmation 
     from Las Cruces. NASA catalog weight=0 (unreliable). NASA catalog 
     ID #805. ALPO/BAA weight=1.


2019-Apr-12 UT 12:59-14:22 Ill=47% Torricelli_B observed by Mobberley_M on 1984-4-8

     On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing 
     III-IV, Transparency Fair-Poor, Cockfield, UK) found that 
     Torricelli B's shadow was 1/2 the way across the floor, which 
     was normal, but that there was a very dar grey/brown shroud 
     around the carter, out to several radii. 
     The ALPO/BAA weight=1.


2019-Apr-12 UT 13:37-15:30 Ill=47% SE_Limb observed by Rohslberger_R on 1980-4-22

     On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West 
     Germany, 8" reflector, x170 25mm occular used, 300mm focal length?) 
     took some photographs using projection. One of these recorded an 
     apparent "ejecta curtain". Cameron considered lens flare, but the other 
     photographs did not show this. If real then the plume was at a height 
     of ~40km and the ray was ~130km. Cameron concludes that this was an 
     impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The 
     ALPO/BAA weight=3.


2019-Apr-12 UT 13:52-15:42 Ill=47% Alphonsus observed by Lenham_AP on 1952-11-24

     Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
     inch efractor x120) noted that the usual dark spots were not 
     visible, but floor ridges and craterlets were surperbly seen. 
     This may not be a TLP but has been given a TLP category as it 
     is a curious appearance and needs to be verified on a repeat 
     repeat illumination apeparance. ALPO/BAA weight=1.


2019-Apr-12 UT 14:35-15:42 Ill=47% W_Limb observed by Miles_H on 1987-1-7

     On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright 
     patches were seen in Earthshine at clock positions of 4 (this patch was 
     defined by the dark limb and the brightness faded inwards to the disk, 
     over a short distance. "Centred at 60 deg along the limb from the north 
     - a sketch showed approximately 10-15 deg along it") and 5:30 (this 
     second patch was smaller and not so bright as the first patch - it was 
     west of the north pole. P. Foley (Kent, UK) also detcted the patches 
     and said that one was not far from the sunrise terminator. 
     The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a 
     weight of 2. The ALPO/BAA weight=2.

     weight=1.


2019-Apr-13 UT 10:46-12:28 Ill=58% Moon observed by Cameron_W on 1969-11-18

     On 1969 Nov 18 at UT 00:30-02:30 W. Cameron (Greenbelt, MD, USA, 12" 
     reflector, x80 and x320) using a low power eyepiece, observed that 
     bright craters (but not all of them) "glittered like diamonds". These 
     craters were several on the terminator, Proclus, Censorinus, Manillius, 
     Menelaus and Dionysius. The glitter effect was on the west wall crest 
     -- like stars. Higher power revealed these areas to be bright but not 
     star-like (nor glittering). The Cameron 1978 catalog ID=1212 and the 
     weight=1. The ALPO/BAA weight=1.


2019-Apr-13 UT 10:46-12:18 Ill=58% Eratosthenes observed by Bartlett on 1976-8-4

     Eratosthenes 1976 Aug 04 UTC 02:07 Observed by Bartlett (Baltimore, MD, 
     USA, S=6, T=3, 4.5" reflector 40-450x) "faint spot of light 4 deg 
     bright seen in shadow on pos. of c.p. which is normally invis. At base 
     of inner NW wall a faint bluish radiance (gas?) was observed". NASA 
     catalog weight=4 (high). NASA catalog ID #1439.

     Piton 2004 Jan 30 UT 15:52 Observed by a GLR observer (Italy) "CCD 
     image shows a point of light in the NW shadow - possibly highland 
     starting to emerge from the shadow?" A GLR report.


2019-Apr-13 UT 11:15-13:11 Ill=58% Plato observed by Schroter on 1789-7-30

     Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany) 
     NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described 
     as: "Soon after sunrise saw a kind of fermentation on the floor which 
     clearly resembled a kind of twilight, (due to some kind of aberration 
     unknown to the observer?)" For further details see reference:

2019-Apr-13 UT 12:18-14:14 Ill=58% Eratosthenes observed by Lenham_AP on 1952-11-25

     Eratosthenes 1952 Nov 25 UT 16:30 A.P. Lenham (Swindon, UK, 3-
     inch refractor x150, Definition Good) noted that there was 
     faint/slightly bright detail inside the interior shadow - 
     observer comments "presumably peaks of central mountains & W. 
     Wall ridge, but very faint" - however this is worth checking 
     out. ALPO/BAA weight=1.


2019-Apr-13 UT 13:03-14:59 Ill=58% Alphonsus observed by Lenham_AP on 1952-11-25

     Alphonsus 1952 Nov 25 UT 17:15 A.P. Lenham (Swindon, UK, 3-
     inch refractor) noted that the usual dark spots were not 
     visible. This may not be a TLP but has been given a TLP 
     category as it is a curious appearance and needs to be 
     verified on a repeat repeat illumination apeparance. ALPO/BAA 
     weight=1.


2019-Apr-13 UT 13:16-14:39 Ill=58% Eratosthenes observed by Abel_P on 2009-11-25

     On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK, 
     15" reflector, seeing II-III, transparency very good), all saw visually 
     a brownish tinge on the north west rim of Eratosthenes crater. P.Abel 
     made a sketch and T.Little took some high resolution CCD images, some 
     of which were through coloured filters. Checks were made for spurious 
     colour, but none was seen elsewhere on the Moon. The eyepiece was 
     changed but this made no difference. M.C.Cook (Mundesley) was observing 
     with a smaller scope at the same time, but saw no colour, however 
     observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was 
     observing with a instrumenet mid way in size, and saw a brownish tinge 
     in the NW rim area, but saw a similar colour elsewhere and put this 
     down to spurious colour. Normally multiple observers seeing the same 
     thing would result in a weight of 4, however as this was only observers 
     at Selsey and some of the evidence contradicts, I am allocating an 
     ALPO/BAA weight=3.


2019-Apr-13 UT 13:32-15:25 Ill=58% Pallas observed by Stuart_L on 1953-11-15

     Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA) 
     "Saw and photographed a bright spot on term. between these two 
     craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog 
     ID #559. ALPO/BAA weight=5.


2019-Apr-13 UT 13:34-15:31 Ill=58% Eratosthenes observed by Galdies_C on 2012-8-25

     On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C. 
     Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4 
     Registaxed images were produced covering 19:45, 19:48, 19:49, 
     and 19:51. All but the first image, once first order spurious 
     colour had been removed, showed orange on the shaded terraces on 
     the western illuminated rim (similar to what Paul Abel and 
     others saw in 2009, albeit just confined to the NW rim), and the 
     interior floor shadow was slightly smaller in red light. However 
     orange colour was also seen on the eastern side of mountains to 
     the south of the crater, which infers that the spurios colour 
     removal did not fully acomplish its main goal. The effects were 
     not caused by the registax software as the orange colour is 
     visible on individual images. Although probably the colour is 
     not lunar in orgin, its explanation is not fully explaianed, 
     therfore an ALPO/BAA weight of 1 is used for now.


2019-Apr-13 UT 14:26-16:20 Ill=59% Aristarchus observed by Loocks on 1969-11-18

     On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector) 
     observed a flash of light of magnitude 12. Cameron speculates a meteor 
     and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and 
     weight=1. The ALPO/BAA weight=1.


2019-Apr-13 UT 14:37-16:34 Ill=59% N_Pole observed by Harris on 1912-1-28

     North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed 
     by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black 
     curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1 
     (very low) and ID=334. ALPO/BAA weight=1.


2019-Apr-13 UT 14:58-16:35 Ill=59% Eratosthenes observed by Longshaw_N on 2017-5-4

     Eratosthenes: On 2017 May 04 UT 21:50-22:10 N. Longshaw (BAA, 
     UK, 78mm APO refractor, x125 & x175, seeing II-III, 
     transparency Good). A brownish (orange) tint was seen on the 
     inner NW wall light terraces - this was immediately obvious 
     when first looking at the crater, but as time progressed the 
     effect became less bright. Other craters were checked for 
     similar coloured tints, but none were seen elsewhere on the 
     Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been 
     imaging the region in colour 17:57-21:47, but their images do 
     not show any colour on the inner NW rim terraces, the their 
     last image is 3 min before Longshaw saw the colour. The 
     ALPO/BAA weight=2.


2019-Apr-13 UT 15:18-16:35 Ill=59% Eratosthenes observed by Hill_H on 1947-1-30

     Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main 
     peak of massive central mountain group appeared to be in a shadowless 
     having regard to it's claimed height of 6,600 ft. The whole of the 
     floor to the west should have still been in darkness. Instead 
     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."

     On 1980 Apr 24 at 23:35UT Marco Petek (Porto Alegre, Brazil, 
     using a 7.5" refractor noticed that the center of Plato was 
     bright and opaque and the observer thought it was similar in 
     appearance to Linne. A sketch was made and two other observers 
     confirmed the appearance. Cameron mentions that Petek is an

     On 1985 mar 01 at 20:00UT? Moseley noticed a violet band (tapering to 
     an apex close to the crater centre and merged with the eastern 
     exterior) around Toricelli B, however M. Cook (Frimley, UK) had seen a 
     dusky band(England, UK) on an earlier photo. There was no terminator

2019-Apr-15 UT 10:48-11:07 Ill=79% Censorinus observed by North_G on 2007-10-21

     At approximately 18:43UT observer noticed that Censorinus, and 
     its bright apron, appeared particularly brighter than normal. 
     There was some spurious colour present - but just a redness 
     along the southernmost extent of the apron visible; could not
     detect any blue along the northern edge however, he did do not
     suspect the colour to be anomalous. A re-examination at 18:51UT 
     revealed that the crater had faded and was seen to fade visibly 
     in real time to normal levels (over about a minute) by 18:53UT. 
     Other features remained constant and so too did the apparent 
     spurious colour.

2019-Apr-15 UT 12:33-14:24 Ill=80% Gassendi observed by Grego_P on 2011-10-7

     On 2011 Oct 07 UT 21:45 Gassendi observed by P. Grego (St 
     Dennis, UK,300m Newtonian, x150, seeing III, intermittent cloud) 
     - whilst producing some sketches of the crater - observer 
     noticed a faint point of light inside the shadow filled 
     interior, two thirds of the way out from where the central 
     peaks should have been, towards the SE rim. Some uncertainty in 
     being sure about this spot and after interuption by cloud it was 
     not seen later that evening. ALPO/BAA weight=1 to refelct 
     uncertainty of observer.


2019-Apr-15 UT 12:53-14:51 Ill=80% Bullialdus observed by Cook_MC on 1979-6-5

     Bullialdus 1979 Jun 05 UT 22:00-23:00 Observed by Cook M.C. 
     and J.D. (Frimley, UK, 12-inch reflector, Seeing III-IV, good 
     transparency). MC Cook observed internittently over this time 
     period (due to cloud) and found the crater sharper in a blue 
     filter than in a red filter. No obscuration seen apart from a 
     darkish patch on the SW rim and spreading over onto an area 
     surrounding the rim, which she took to be shadow, though the 
     main shadow was along the east rim of the crater. JD. Cook 
     observed an orange colouration seen on eastern and the cleft 
     on the SW rim. Dark area seen on southern floor of crater, 
     south of central peak. ALPO/BAA weight=1.


2019-Apr-15 UT 14:32-16:29 Ill=80% Eimmart observed by Louderback_D on 1981-4-15

     On 1981 Apr 15 at UT06:27-06:40 D. Louderback (South Bend, WA, USA 
     using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on 
     the western wall of Eimmart (sketch supplied) have an unusual 
     brightening and shade. Variations occurred over 2-3 minute intervals. 
     Louderback commented that the spot looked like a flare with its apex 
     located at the crater wall and there was some blurring effect on the 
     spot - it decreased in size during the phenomenon. Seeing worsened 
     later. Apparently on the 18th and 19th of April everything was back to 
     normal. Cameron comments that there is no bright spot on the Moon at 
     this location. Lunar Orbiter IV plates 192-3.2 shows evening 
     conditions. Cameron 2006 Catalog Extension TLP ID=130 and weight=3.

     A.R. Neville (Burnley, UK, 6" reflectir, x192, slight fog, 
     seeing jumpy but good at times). An in ititial Moonblink 
     search proved negative. However white light observations by 
     Coates revealed a golden brown colour between the black 
     interior shadow and the base of the (bright W (IAU?) wall). 
     Neville confirmed its appearance as a coppery hue and saw the 
     colour for 5 minutes before it vanished at 22:55UT. ALPO/BAA

     6" Cassegrain, x150 and x180, Seeing 3, high deck of Cirrus clouds) 
     "Torricelli B hard to make out in the videos taken, but images taken 
     through cloud. A check on the image received by the coordinator shows 
     that Torricelli B is in fact visible, but perhaps not very bright. A 
     later observational sequence of images by Raul Salvo (Montevideo, 
     Uraguay UT 03:15-03:23) showed similarly that Torricelli B was dark, 
     and there was some brightness variability although the 
     background setting on these was low" An ALPO report.


2019-Apr-16 UT 12:35-14:32 Ill=88% Bullialdus observed by Gray_R on 2006-12-2

     At 03:30UT observer noticed a hint of yellow colour
     on the floor of the crater and by 03:57UT the south
     east and central parts of the floor and the circular
     feature on the south west floor had turned a deep
     yellow colour. The rest of the crater remained colourless.
     Other craters also remained colourless. By 04:05UT the colour
     was fading and by 04:15UT it was gone. Maurice Collins
     in New Zealand took some low resolution colour images about
     4 hours later but these failed to show any yellow colour.
     Zac Pujic obtained colour images at a different time of
     natural surface colour on the Moon and finds that Bullialdus
     does actually have a natural yellow cast to most of the floor.
     However this does not explain the variability in colour strength
     seen by Robin Gray. ALPO/BAA weight=3.

     than the inner wall but brighter than the outer wall. The Cameron 1978 
     catalog ID=292 and weight=5.


2019-Apr-16 UT 13:21-15:18 Ill=89% Plato observed by Moore_P on 1987-1-11

     On 1987 Jan 11 at UT P. Moore (Sussex, UK) found the the floor of Plato 
     was much more drk than the adjacent Mare Imbrium. Furthemore there was 
     a blurring of detail over the northeast wall and onto the nearby floor. 
     detail elsewhere in the crater was OK. By 23:00UT there was less lack 
     of detail effects. M. Cook (Frimley, UK) at 21:55UT noted the obscured 
     area but decided that it was narrower than the same effect one month 
     ago and suspected that she may have been observing towards the end of 
     this TLP. The effect gradually dimmed between 21:55 and 22:45UT. Other 
     craters were normal. G. North was affected by poor seeing conditions. 
     Davies detected a slight obscurtion on the north east corner - it was a 
     misty gray feature at x200. The Cameron 2006 catalog extension ID was 
     292 and the weight was 5. Tha ALPO/BAA weight was 4.

     (Montevideo, Uraguay UT 03:15-03:23) showed that Torricelli B 
     was dark, and there was some brightness variability although the 
     background setting on these images was low and seeing could 
     account for the brightness variation? An ALPO report.


2019-Apr-16 UT 14:27-16:18 Ill=89% Gassendi observed by Darling_D on 1990-10-1

     On 1990 Oct 1st at 00:44-01:24UT D Darling (Sun Praire, WI, USA) 
     observed that Gassendi still had a blink effect when viewed through 
     blue (Wratten 38A) and red (Wratten 25A) filters. No effect was seen on 
     Aristarchus. Gassendi was brighter in the red filter and this was 
     confirmed by Weier. Sketches were made and brightness measurements 
     taken. Both observers used a 12.5" reflector x159. At 01:00UT the NW

     Hobdell, of St Petersburg, FL, USA, using a 2"? refractor?
     and Seeing=I-II, saw a bright region on the north west wall
     that seemed to change in brightness. In truth, there were
     other features elsewhere on the Moon that also fluctuated,
     but not as much as Aristarchus was. No colour was noticed.

2019-Apr-17 UT 10:50-11:07 Ill=95% Aristarchus observed by Foley_PW on 1978-5-19

     P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed
     that initially that the crater was pretty dull and that the floor
     was a slate blue-gray in colour at 22:45UT. A noticeable green spot
     inside the crater on the south east appeared at 22:25UT and vanished
     at 00:50UT. Cameron notes that one doesn't get green with spurious 
     colour. Crater Extinction brightness measurements were made at 22:00 UT
     (reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in

2019-Apr-19 UT 12:43-14:04 Ill=100% Aristarchus observed by Darling_D on 1990-12-2

     F. Graham took some photos of the Cobras Head and found a blue cloud 
     about 50 km in diameter and scattering light - Cameron says that 
     this indicates high density. Darling found the Cobra's Head obscure and 
     variable "clear and bright to diffused". Cameron was alerted observed 
     (02:40UT) variations with periods of approximately 30 seconds, and 
     thought that she could see a red tinge on the east rim of Aristarchus - 
     checks elsewhere found no other colours. Darling found that a blue 
     filter enhanced the effect and a red filter made it disappear. There 
     was a blink at 02:55UT but no blink in the Cobra's Head, which looked 
     fuzzy and lacking in detail. The effect was confirmed by Weier, who 
     also saw two dark spots in the Cobra Head in blue but not in red light. 
     The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall 
     7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south 
     wall 7.0, East wall 8.0, and the central peak 10.0. Observer details

     On 1955 Oct 02 at UT 05:30-05:55 Bartlett (Baltimore, MD, USA, 3.5" 
     reflector, x100, S=7, T=5) observed the following in Aristarchus 
     crater: "Viol. gl. on E, NE rim, over EWBS resembled a viol. mist.

2019-Apr-20 UT 14:00-15:14 Ill=98% Torricelli_B observed by Mobberley_M on 1985-12-27

     Mobberley noticed that Torricelli B was bright and had an even brighter 
     spot on the inner north wall. The observation was made from UT19:45-
     21:40 using visual and video techniques. There was also a bright region 
     NNE of Toricelli B, that was noticed. Foley examined the video and 
     found that the crater faded in brightness over time and also the bright 
     area to the NNE was not as bright on video as had been seen visually. 
     Foley speculates that because the CCD camera was sesnitive to the near 
     IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and 
     also saw the bright spot on the inner north wall - but saw a blue halo 
     around the crater. Response in blue filter, darkening over whole 
     region. Brightness measures with a crater extinction device (CED) 
     indicated that the crater was 80-85% the brightness of Censorinus. 
     There was a bright area NNE of the region. M. Cook observed 22:10-
     22:16UT (15cm reflector and seeing III-IV) and also saw that the crater 
     was very bright indeed with a spot NNE of the region (same position as 
     28/28 1985 observation) - suspected that the crater might have been 
     brighter than Censorinus, but judgement effected by seeing. In a blue 
     filter the crater dulled leaving the bright spot prominent (but only 
     during a good moment of seeing) - therefore had some suspicion of 
     seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the 
     area, but the seeing was even worse - but did manage a check of the 
     brightness of Torricelli B to Censorinus and now made it one quarter of 
     that of Censorinus and no sign of the crater dimming in the blue as had 
     been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 
     21:15UT (Dec 27) thought that Torricelli B looked normal and saw no 
     colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images 
     through red+IR (Wratten 25) and IR (Wratten 87) but found no colour 
     differences, though there was a very slight hint that a brightness fade 
     may have occurred between those two observing times. Note that this
     report does not have an entry in the Cameron 2006 Extension Catalog.

2019-Apr-20 UT 15:06-17:04 Ill=98% Aristarchus observed by Madej_P on 1984-2-17

     On 1984 Feb 17 at 19:45-22:20UT P. Madej noticed colour in Aristarchus 
     and telephoned the BAA Lunar Secton TLP network. Mosely at 21:15UT 
     observed that Aristarchus was both bright and fuzzy - there was some 
     spurios color (red on south and blue on the north) but this was 
     replaced by violet. By 21:30UT (transparency=fair) the centre of the 
     crater was bluish and the west wall creamy white. the north and south 
     walls were brilliant white. By 22:00-22:30 UT the seeing had improved 
     and the crater looked unusual - now the centre was violet and the west 
     wall duller, off-white. By 05:35UT the crater was difficult to define 
     according to Cook - 4 bands could be seen under II seeing and the north 
     rim was fuzzy and less bright than the east wall (this was hazy). P. 
     Moore observed that the crater was normal at 04:00UT. Cameron 2006

2019-Apr-20 UT 17:40-19:29 Ill=98% Torricelli_B observed by Cook_AC on 1985-12-28

     CCD images taken through Wratten 25 (red+near IR) and 87 
     (near IR only) filters. Between 00:02 and 00:25UT there
     was some slight evidence that a fade may have taken place
     however careful analysis by Cook casts doubt on this.
     Probably it was more related to a degradation in image 
     quality due to seeing than a true TLP. An ALPO/BAA
     weight of 1 has been assigned.

     On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds, 
     Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley 
     examined the tape and noted something that Mobberley had not seen 
     visually. Two scans of Totticelli B had taken place, one at 23:23 and 
     the other at 23:58UT. In the first a brilliant point appeared briefly, 
     on the western rim, positioned at 3o'clock. In the second video 
     sequence this brilliant spot was present continuously and wandered 
     along the rim. It was possible to monitor frequency of turbulence 
     present, this apparent movement did not ppear to conform, although 
     judgement here was extremelydifficult as the feature was at absolute 
     point of resolution, a little better than 0.5 mile. Also considered was 
     the implication of the equipment effect, this did not seem to fit 
     either as other nerby craters in the same configuration, 30% shadow

2019-Apr-22 UT 20:27-21:30 Ill=86% Plato observed by Wilkins_HP on 1944-3-12

     On 1944 Mar 12 at UT 23:00 H.P. Wilkins (Kent, UK, 8.5" reflector) 
     observed that Plato appeared incomplete - the central crater had it's 
     north wall obscured. cameron comments that maybe this was due to the 
     low altitude of the Moon? The Cameron 1978 catalog ID=491 and 
     the weight=4. The ALPO/BAA weight=2.


2019-Apr-22 UT 20:35-21:30 Ill=86% Birt observed by Doherty_EG on 1972-9-25

     Birt 1972 Sep 25 UT 23:20-23:45 Observed by Doherty (Stoke-on-Trent, 
     England, 10" reflector x280, S=VG) "All bright areas were similar in 
     intensity (albedo) but 2 larger ones at times seemed brighter. N & S. 
     The E. IAU? wall of the small craterlet showed most prominently & at 
     times suspected a faint pt. of light just W. of its center. This was 
     very suspect however." NASA catalog weight=1 (very low). NASA catalog 
     ID #1345.

     Darling, alerted by Keyes saw Aris >> brighter obj on moon (as
     it normally is) Comet ray & N rim of Herod. >> could see no
     detail - Aris. except two bands, moon was pale yellow (low alt.)
     with halo around it. Nothing unusual elsewhere. Cameron 2006
     catalog extension ID #384 and weight=0. ALPO/BAA weight=1,
     just in case there is some merit in this report?

     Aristarchus 2004 Dec 02 UT 03:00 Observed bt Michael Amato (West Haven, 
     CT, USA, 127mm Maksutov, x123) "The brightness variation (as seen by 
     Brook earlier) was very apparent. One thing never seen before by Amato 
     was a thin short bright ray that extended out in the opposite direction 
     as Aristarchus bright ray". The higher the Moon climbed in the sky the 
     more obvious this short thin bright ray became. An ALPO report.


2019-Apr-25 UT 20:36-21:26 Ill=60% Calippus observed by Fox_S on 1997-7-25

     On 1997 Jul 25/26 at UT 23:00-00:00 S. Fox (Dundee Tayside, Scotland, 
     UK, 15cm f/5 reflector with x4 Barlow). A series of photographs were 
     taken that show a glow just beyond the terminator, near to Callipus 
     crater. Almost certainly this is lens flare from the Barlow lens. The 
     ALPO/BAA weight=1.

     Tycho 1990 Dec 10 UT 11:03-12:49 Observed by Darling (Sun Prairie, WI, 
     USA, 12.5" Newtonian, x63) "Nebulous patch seen where the central peak 
     should have been in the 90% shadow filled crater. The nebulous patch is 
     seen to vary in size and a star-like point is seen inside it briefly 
     for 1 sec. The nebulous patch was a bit like what one expects from a 
     close-up view of a cometry nucleus. A sketch and an image can be found 
     on the following web site:
