2018-May-02 UT 18:09-21:38 Ill=92% Gassendi observed by Haas_W on 1940-7-22 *

     Gassendi 1940 Jul 22 UT 05:00 Observed by Haas (NM?, USA, 12" 
     reflector?) "Largest bright spot in SE part of floor had I=8.6, 
     but 6+ on other dates. (see #472, 474 & 475). (8.6 is normal?)" 
     NASA catalog weight=4. NASA catalog ID #469. ALPO/BAA weight=3.


2018-May-18 UT 14:05-14:38 Ill=13% 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 
     weight=1. The ALPO/BAA weight=1.


2018-May-19 UT 14:06-15:12 Ill=22% 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.


2018-May-19 UT 14:14-15:37 Ill=22% 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.


2018-May-19 UT 14:14-15:37 Ill=22% 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.


2018-May-19 UT 15:27-15:37 Ill=22% 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 
     catalog ID #358. ALPO/BAA weight=1.


2018-May-19 UT 15:31-15:37 Ill=22% 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.


2018-May-19 UT 15:00-15:39 Ill=22% Earthshine: (radio) Omicron Cetids: ZHR=medium

2018-May-20 UT 14:08-14:28 Ill=32% Aristarchus observed by Mitchell on 1969-11-14

     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.


2018-May-20 UT 14:08-15:03 Ill=32% 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.


2018-May-20 UT 14:08-15:52 Ill=32% 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.   


2018-May-20 UT 14:36-16:24 Ill=33% 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.


2018-May-20 UT 15:18-16:24 Ill=33% 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.


2018-May-20 UT 15:22-16:24 Ill=33% 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.


2018-May-20 UT 15:38-16:24 Ill=33% 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.


2018-May-20 UT 15:58-16:24 Ill=33% 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.


2018-May-20 UT 16:20-16:24 Ill=33% 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.


2018-May-20 UT 15:02-16:26 Ill=33% Earthshine: (radio) Omicron Cetids: ZHR=medium

2018-May-21 UT 14:09-14:46 Ill=44% Censorinus observed by Enie on 1966-12-18

     White spot near Censorinus 1966 Dec 18 UT 23:40-23:46 Observed by Enie 
     (Pittsburgh, Pennsylvania, USA, 8" reflector x100, S=G) "Attention 
     drawn to pink color in this usually white patch. Brightened to a light 
     reddish tinge for 2 mins, then faded back to pink, then to white, 
     Sketch." NASA catalog weight=4 (high). NASA catalog ID #1002.


2018-May-21 UT 14:35-16:32 Ill=44% 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.


2018-May-21 UT 15:40-17:02 Ill=44% 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.


2018-May-21 UT 16:27-17:02 Ill=45% 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. 


2018-May-21 UT 15:04-17:04 Ill=45% Earthshine: sporadic meteors

2018-May-22 UT 14:11-15:16 Ill=55% 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.


2018-May-22 UT 14:11-15:16 Ill=55% 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.


2018-May-22 UT 14:11-15:16 Ill=55% 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.


2018-May-22 UT 14:11-15:16 Ill=55% 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.


2018-May-22 UT 14:21-16:15 Ill=55% 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.


2018-May-22 UT 14:40-16:37 Ill=55% 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.


2018-May-22 UT 14:40-16:37 Ill=55% 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.


2018-May-22 UT 14:47-16:42 Ill=55% 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.


2018-May-22 UT 15:34-17:16 Ill=56% 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.


2018-May-22 UT 16:20-17:32 Ill=56% 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.


2018-May-22 UT 16:36-17:32 Ill=56% 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.


2018-May-22 UT 17:21-17:32 Ill=56% 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.


2018-May-23 UT 14:12-15:54 Ill=66% 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:

     Sulpicius Gallus 1867 Jun 10 UT 22:00? Observed by Dawes 
     (England?) "3 distinct roundish black spots. Absent on 13th" 
     NASA catalog weight=3. NASA catalog ID #184. ALPO/BAA 
     weight=1.


2018-May-23 UT 14:12-15:13 Ill=66% 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.


2018-May-23 UT 14:12-14:59 Ill=66% Eratosthenes observed by Bartlett on 1976-8-4

     Eratosthenes 1976 Aug 04 UTC 02:07 Observed by Bartlett (Baltimore, MD,

2018-May-23 UT 14:12-15:36 Ill=66% Mons_Piton observed by Unknown_Italian_Observers on 2004-1-30

     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.


2018-May-23 UT 15:01-16:57 Ill=66% 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.


2018-May-23 UT 15:45-17:42 Ill=66% 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.


2018-May-23 UT 15:49-17:32 Ill=66% 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.


2018-May-23 UT 16:13-17:55 Ill=67% 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.


2018-May-23 UT 16:19-17:55 Ill=67% 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.


2018-May-23 UT 17:07-17:55 Ill=67% 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

2018-May-23 UT 17:41-17:55 Ill=67% 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.

     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.


2018-May-25 UT 15:34-17:27 Ill=85% 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.


2018-May-25 UT 17:11-18:26 Ill=85% 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.

     Gassendi 1971 Oct 29 UT 22:15-22:50 observed by J.Coates and 
     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

     "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.

2018-May-26 UT 15:13-17:07 Ill=91% 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.


2018-May-26 UT 15:26-16:29 Ill=91% Mersenius_C observed by Ward_G on 2005-11-13

     G. Ward (a lunar observer for 15 years) observed an area just south 
     west of Mersenius C to be blurred and in a greenish cloud. The green 
     colour was more like that of dead grass than one gets from a neon bulb.
     The effect was seen from 04:50-04:57UT, but could have been going on 
     before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor 
     (2 element). refractor had been used hundreds of hours before (over a 
     10 year period) with no similar colour was seen. The observer checked 
     other areas but did not see any similar effects. They also rotated and 
     changed eyepieces, but this made no difference to the TLP. The TLP site 
     seen was picked up on an image taken earlier at 04:47UT by W. Bailley,
     from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on 
     the image, was saturated and so we cannot tell if a colour was present 
     there and the seeing was poor.


2018-May-26 UT 15:59-17:51 Ill=91% Timocharis observed by Firsoff on 1954-10-8

     Observed by Firsoff (Somerset, England, 6.5" reflector? x240) "Red 
     glow." NASA catalog weight=4 (high). NASA catalog ID #573.


2018-May-26 UT 16:00-17:52 Ill=91% Aristarchus observed by Grego_P on 1987-1-11

     On 1987 Jan 11 at UT 18:15-23:00 P. Grego (Birmingham, UK, 6" 
     reflector, seeing=III) sketched Aristarchus crater and saw two luminous 
     circular patches on the exterior west wall - these were less bright 
     than the inner wall but brighter than the outer wall. The Cameron 1978 
     catalog ID=292 and weight=5.


2018-May-26 UT 16:00-17:52 Ill=91% 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.


2018-May-26 UT 16:13-18:05 Ill=91% Gassendi observed by Unknown_Observer on 1889-5-11

     On 1889 May 11 at 22:00? UT an unknown observer saw an ink black spot 
     on the rampart of Gassendi. It had not been seen before ar at the next 
     lunation or indeed ever again. Cameron 1978 catalog ID=261 and 
     weight=3. ALPO/BAA weight=2.

     England, 18" reflector) "I was examining the Cobra Head of the Schroter 
     Valley, when I noticed what seemed to be a diffuseed patch of thin 
     smoke or vapour, apparently originating from the valley on the E. Side 
     where the landslip is, and spread over the edge on to the plain for a 
     short distance. Every detail of the edge of the valley was perfectly 
     clear and distinct except where this patch occurred, but there the 
     definition was poor and very blurred" NASA catalog

     orange color in crater. After clouds passed at 2300h color still there 
     & gave a slight blink which no other craters did. Not seen in red 
     filter, dark in blue. Ford saw it along ridge fr. c.p. to SW wall.

2018-May-26 UT 16:36-18:28 Ill=92% Torricelli_B observed by Salvo_R on 2005-1-22

     Torricelli B 2005 Jan 22 UT 03:15-03:23 Observed by Raul Salvo 
     (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.


2018-May-26 UT 17:00-18:33 Ill=92% 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 
     wall was 7.5, the SW wall 8.0, the S. wall 7.5, the floor 6.0, the

2018-May-26 UT 18:17-18:33 Ill=92% Aristarchus observed by Hobdell on 1981-4-16

     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.
     Cameron suspects fluctuations in our own atmosphere.

2018-May-26 UT 18:55-20:07 Ill=92% Deslandres observed by Penzel_E on 1965-5-12 *

     On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was 
     taking a sequence of images during the impact of the Soviet Lunik 5. He 
     detected a tens of km scale elongated cloud after the impact over a 
     duration of 9.5 minutes. However there are differences between the 
     images elsewhere on the Moon, possibly due to different exposures or 
     some other effects and it is not 100% sure that what he detected was 
     impact debris/cloud?. The ALPO/BAA weight=3.


2018-May-27 UT 14:48-15:34 Ill=96% Aristarchus observed by Johnson on 1937-9-17

     Johnson, of Des Moines, Iowa, USA, using a 7" reflector and an 8" 
     refractor, saw a bight streak. The observer looked later, but it was no 
     longer visible. Cameron thinks that it might have been a reflection 
     from the wall. Cameron 1978 catalog ID=423 and weight=1. ALPO/BAA 
     weight=1.
