2019-Apr-09 UT 15:21-15:38 Ill=18% Taruntius observed by Buczynski_DG on 1980-4-19

     On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the 
     Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood) 
     who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had 
     located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was 
     very bright in W25 (red), dull but vis. In W44A (blue) & floor was 
     noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was 
     of a light shade. Other craters checked for color, none found. In 44A 
     floor lost some definition (gas?). Sketches from Bucz. & Greenwood. 
     (Pedler) at 2140, floor area around cp was seen in white & red as 
     normal but blink was vis in white, darker in blue. Checks of other 
     features were negative. (Amery) small dark center & small dark area - 
     not shadow - under S wall. N wall obscured by dark area extending N 
     onto surrounding mare. (normal?) which was difficult to focus (gas?). 
     At 2155 N wall now sharper & dark area less intense. Craterlet Cameron 
     in N wall clearly seen which was invisible 1/2 h earlier. (Saxton) 
     whole crater flashed and blinked at 2155. Could see detail in brighter 
     W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was 
     normal. (Blair) at 2155 used red & blue filters & in blue it was darker
     than in red. W. wall not well defined. (J. Cook) saw spurious color on

2019-Apr-10 UT 15:21-16:11 Ill=27% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teignmouth, UK, 10.5" 
     reflector, x180) found, using a Moon Blink device, evidence of colour 
     on the flor patches of Fracastorius crater, brighter in blue than in 
     red. Also the floor to center varied in brightness in blue and in red. 
     Peters observed in white light and found the south east-south wall had 
     a slight orange cast and when a Moon blink was used it was less bright 
     in blue than in red light. M. Cook found spurious colour on the south 
     rim and also on Mons Pico. There was a colour blink reaction on the 
     southeast floor of Fracastorius - this was both faint and blurred and 
     not seen in white light. A.C Cook detected the permanent blink in the 
     south east floor of the crater at 21:47 and a fainter one in the north 
     west (marginally brighter in red than in blue). J.D. Cook found no 
     colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong 
     colour reaction with the Moon Blink device - brighter in red than in 
     blue and detected a pink colour visually on the south east wall 22:10-
     22:45 (this did not give a blink effect though). Cameron 2006 catalog 
     ID=88 and weight=4. ALPO/BAA weight=2.


2019-Apr-10 UT 15:21-15:26 Ill=27% 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 15:21-16:37 Ill=27% Petavius observed by Blair_G on 1980-4-20

     On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used 
     an 8" reflector and seeing=III) saw three patches in Petavius and they 
     could still be seen 7 minutes later. At 21:50UT he used a filter and 
     found the "northern one was brighter in blue, the southern one was 
     brighter in red and the central one was the same shad ein both 
     filters." Cameron comments that the central patch was a permananent 
     one. She then goes onto say that the crater is described as having dark 
     patches that are opposite to what one would expect from Fitton's theory 
     applied to dark features. Cameron 2006 extension catalog ID=88 and 
     weight=4. ALPO/BAA weight=2. 


2019-Apr-10 UT 15:45-18:05 Ill=28% Earthshine: sporadic meteors

2019-Apr-11 UT 15:20-15:31 Ill=37% 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 17:16-18:58 Ill=38% Messier observed by Klein_HJ on 1878-11-1

     Messier 1878 Nov 01 UT 20:00? Observed by Kleis (Cologne, Germany, 6" 
     refractor?) "Shaped like a half moon with E. edge missing. Appeared 
     diffuse. Messier A was sharp & completely defined. Was sure there was 
     fog there. Next day same appear. Shadow was diffused before noon, Mess. 
     A is more yellow after noon, greener near Mess. A noon, both are same 
     color." NASA catalog weight=4. NASA catalog ID #206.
     ALPO/BAA weight=2.


2019-Apr-11 UT 17:17-17:36 Ill=38% Aristarchus observed by Butler_FC on 1981-3-12

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's 
     2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA 
     weight=2.


2019-Apr-11 UT 18:33-18:58 Ill=38% Mont_Blanc observed by Schroter on 1789-9-26

     On 1789 Sep 26 at UT 03:30 Schroter (Lillienthal, Germany) observed 
     close beneath Mons Blanc at the west foot, in the dark, a small 5th 
     magnitude, speck of light. Its round shadow was sometimes black, 
     sometimes grey. Cameron suspects that this is the same as her TLP 
     report No. 50. the Cameron 1978 catalog ID=62 and weight=4. The 
     ALPO/BAA weight=3.


2019-Apr-11 UT 15:45-19:00 Ill=38% Earthshine: sporadic meteors

2019-Apr-12 UT 15:20-15:48 Ill=48% 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 15:20-15:30 Ill=48% 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 15:20-16:32 Ill=48% 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.


2019-Apr-12 UT 16:07-17:53 Ill=49% Alphonsus observed by Hopp on 1972-9-15

     pp53-61.


2019-Apr-12 UT 16:59-18:27 Ill=49% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the 
     "Observations and Comments" column in the December, 1953 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.


2019-Apr-12 UT 17:13-19:10 Ill=49% Messier observed by Klein_HJ on 1878-11-2

     Messier 1878 Nov 02 UT 20:00? Observed by Kleis (Cologne, Germany, 6" 
     refractor?) "Shaped like a half moon with E. edge missing. Appeared 
     diffuse. Messier A was sharp & completely defined. Was sure there was 
     fog there. Next day same appear. Shadow was diffused before noon, Mess.

2019-Apr-12 UT 17:23-19:16 Ill=49% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.

     to E, shadow." NASA catalog weight=3 (average). NASA catalog ID #501.


2019-Apr-12 UT 17:46-19:43 Ill=49% Curtis observed by Williams_AS on 1882-8-21

     Williams of the UK, on 1882 Aug 21 at 19:30UT (Moon's age 7.9 
     days) noticed a spot at least half as bright, and as large as 
     Picard, near to Picard crater. This observation was reported 
     in the Astronomical Register of the Royal Astronomical Society 
     and is not included in the Cameron catalogs. It is one of many 
     measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness 
     points spotted on a graph by Willaims. The ALPO/BAA weight=3.

     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

     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."

2019-Apr-13 UT 15:20-15:32 Ill=60% 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 15:20-16:55 Ill=60% 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.

     On 1981 May 12 UT 22:00? M.C. Cook (Frimley, UK and using a 12" 
     reflector), noticed that Censorinus was very bright, fuzzy and 
     occasionally brighter than Proclus. However both Foley (Kent, UK) and 
     Amery (Reading, UK) using a C.E.D. found that Proclus was brighter than 
     Censorinus as it had been during April and May 1981. However Chapman 
     obtained the reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=2.


2019-Apr-13 UT 18:10-20:02 Ill=61% Proclus observed by Darling_D on 1989-12-6

     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.

2019-Apr-14 UT 20:14-21:58 Ill=72% Curtis observed by Williams_AS on 1882-8-23

     Williams of the UK, on 1892 Aug 23 at Moon's age 10.0 days, noticed a 
     spot now rated at +1.5 (in brightness) that had been seen on the 21st 
     Aug, near Picard. Williams comments that this is the only obsewrvation 
     that departs "much" from the curve of diurnal brightness. The spot was 
     descibed as "nearly as large as Picard and nearly half as bright. This 
     observation was reported in the Astronomical Register of the Royal 
     Astronomical Society and is not included in the Cameron catalogs. It is 
     one of many measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness points 
     spotted on a graph by Willaims. The ALPO/BAA weight=3.

2019-Apr-14 UT 21:24-21:58 Ill=73% Moltke observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clear what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) 
     noticed that Moltke was very bright with a fuzzy violet hue - he had 
     never seen it like this before. Cameron 2006 catalog extension TLP ID=

2019-Apr-14 UT 21:24-21:58 Ill=73% Plato observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clerr what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) saw 
     initially no craterlets in Plato, despite the Moon being at a high 
     altitude. At 01:45UT the northwest corner of Plato was red. Again no 
     other craterlets showed. He found the surrounding wall to be too bright 
     and this was confirmed by Crater Extenction Device readings and had 
     problems focussing on the crater. By 02:00-02:50UT he noticed 
     variability in the visibility of the craterlets. By 03:48UT the central 
     craterlet was much brighter than before and the crater doublet had 
     brightened but the southern craterlet was still invisible. Cameron 
     comments that Marshall was a very experienced observer. A. Cook (of 
     Frimley, UK) obtained a photodiode line scan image of Plato. The 
     brightness of the north west wall was brighter than the bright area on 
     the west wall. Marshall and Mosely both saw a dark area on the floor of 
     Plato close to the south wall (from clock position of 11 o'clock. There 
     was a prominent white spot on the floor and the central craterlet was 
     seen, but only under good conditions. Mosely does not discuss the west 
     and north west wall brughtnesses that were seen earlier by Cook and 
     Marshall. Cameron 2006 catalog extension TLP ID=240 and weight=2.

2019-Apr-15 UT 15:19-16:29 Ill=81% 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

     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

     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.


2019-Apr-16 UT 15:18-16:18 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 
     wall was 7.5, the SW wall 8.0, the S. wall 7.5, the floor 6.0, the 
     outer E. wall 8.0, the N. floor 5.5. Gassendi A W. wall was 9.5,l 
     Aristarchus W. floor was 8.0, NW wall 8.0, shadowed floor 0.0, E. outer 
     wall 7.0, NBP 5.5, area between Aristarchus and Herodotus 6.0, and the

     (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 15:39-17:36 Ill=89% 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.

     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6

     Aristarchus floor (point F) brightened rapidly from an intensity of 5.2 
     to 6, however at 07:08 UT the spot returned to normal. He also noticed 
     that the bands on the walls varied every few minutes. A mist like 
     appearance was seen on the floor of Aristarchus. Through a red filter 
     he could see through the haze, but floor detail could not be seen 
     through a blue filter. Cameron 2006 extension catalog ID=316 and

     abnormal.


2019-Apr-17 UT 22:20-00:16 Ill=96% Aristarchus observed by Louderback_D on 1980-4-28

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

     Louderback observed that the south west wall was a creamy deep yellow.
     There was also strong fluorescent blue on the west wall of the Cobra
     Head - Schroter's Valley area and this was similar to the violet glare
     seen on Aristarchus at times. Violet was seen between Aristarchus and
     the Cobra Head. Seeing coditions were poor. Brightening of a point
     near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
     (Cameron concludes that this was not due to the Earth's atmosphere).
     A 0.2 step drop in brightness was seen on point A (twin spots).
     Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.

     On 1989 Oct 14 UT 19:00?, 22:00? P.W. Foley (Kent, U.K., using a 12" 
     reflector) noted that although the brightness of Aristarchus crater 
     seemed steady, that there was just too much detil to see inside the

2019-Apr-19 UT 23:06-00:53 Ill=100% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended
     catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2.

     x120 - no cloud, slight haze, no wind, seeing good) noticed during 
     first part of observing period that Aristarchus was getting steadily 
     brighter, very much brighter than Proclus. This continued until 02:36UT 
     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2.

     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2. Just as an after thought - was 
     it Aristarchus that was varying, or Proclus?


2019-Apr-20 UT 00:32-02:29 Ill=99% Eimmart observed by Louderback_D on 1980-4-30

     Louderback, of South Bend, WA, USA observed a bright area over
     Mons Anguis and Eimmart - it resembled a comet and had a bluish 
     colour and varied in brightness. The colour was confirmed as it 
     was not seen in a red filter but could be seen in blue and white 
     light. Other features were checked but did not show anything 
     similar although a violet glare was suspected in the blue filter. A
     sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.
     Noted that the area around Eimmart appeared opaque at times and less so
     at other times. At 08:52UT the phenomenon was seen again. On May 2nd 
     a bright spot was still seen in the region but it was not changing 
     dimensions. During the observation on Apr 30th the atmospheric
     transparency was excellent. A 2.5" refractor was used. Reference:
     Personal communication from Louderback to Cameron on 1980 Jul 16th.
     The Cameron 2006 catalog extension ID of this TLP was 93 and the 
     weight was 4. ALPO/BAA weight=3.


2019-Apr-20 UT 17:54-19:28 Ill=97% 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.
