2024-Feb-01 UT 02:04-03:43 Ill=68% 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.

2024-Feb-01 UT 05:47-06:46 Ill=67% Aristarchus observed by Gray_R on 2004-12-3

     Observations made with a variable polarizer (akin to a crater
     extinction device) to measure brighness with red and blue filters.
     Some variability in brightness noted. With the Kodak Wratten
     25 and 38A filters there was little or no increase in contrast with the 
     red filter, but with the blue filter there was a great increase in 
     contrast of the brighter areas of the crater - the crater floor and 
     patches of lighter material, especially at the north end. The remaining
     areas were supressed with the Blue 38A. ALPO/BAA weight=3.

     On 1994 Jun 14 UT 21:45-22:00 G.Rogers (Crendon, UK, 3" Zeiss 
     refractor, sky conditions perfectly clear) reported seeing three 
     very large whitish clouds against the Moon. The strongest seemed 
     to "stem" from the vicinity of Santbech crater (crater 
     identified the next day from an atlas), and was a milk chocolate 
     colour near the stem. The other two large clouds were to the 
     north - in the general area of Mare Fecunditatis and Mare 
     Crisium though perhaps slightly further west and in contact with 
     the terminator? The effect was confirmed (independently) by 4 
     other observers using the same telescope. The telescope was 
     moved but the clouds remained in the same position over the 
     Moon. This report comes from The Astronomer Jan 2013 p 230.

     On 1981 May 10 at UT02:16-03:12 B. Hobdell (St Peterburg, FL, USA, 2?" 
     refractor, the Moon was at a very low altitude) found that the NNW wall 
     of Aristarchus increased in brightness and extended to an arc of the 
     east wall. There were bright flashes in roughly 2 minute intervals. 
     There were also two yellow spots at 5 and 8 o'clock on the east wall. 
     At 02:44UT a bright yellow flash was seen on the NNW rim and by 02:49UT 
     the complete crater was very bright, inparticular on the western wall. 
     Further bright flashes were seen at 02:52UT and at 03:11UT many bright 
     blue points were seen. Finally an obsecuration was seen at 03:12UT. The 
     observer checked for spurious colour but none was seen. The Cameron

2024-Feb-15 UT 22:03-22:22 Ill=42% Aristarchus observed by Nottingham_University on 2006-11-26

     CCD images were captured in white light that seemed to show that
     the relative brightness between Aristarchus or Pytheas differed
     considerably to what they were to be one night earlier on 2008 Nov 25.
     Either Pytheas was brighter tonight or Aristarchus was darker.
     Which feature, and which night, the abnormality occurred on is 
     uncertain. One possible explanation might be a brightness
     gradient from glare from the sunlit side affecting the image contrast
     quality of the CCD images for relative photometric measurements.
     This TLP is being assigned a weight of 3 for now.

     On 1979 Jul 01 at 22:00?UT D.J. Raden (Fort Meade, FL, USA, using a 
     10" reflector) detected a flare near to Halley (5E, 9S) visually with 
     the eye and it lasted about 3-4 min - a sketch was made. However it was 
     also found on one photographic slide taken with an exposure of 35 
     seconds. The observer comments that visually the flare was not as 
     bright as it appeared in the photograph. In an area near Halley. The

2024-Feb-17 UT 17:10-18:55 Ill=62% Proclus observed by Mobberley_M on 1987-11-28

     On 1987 Nov 28 UT at 20:14 (possibly earlier)-20:44 M.Mobberley saw the 
     northern rim of Proclus very bright for first quarter. There were 
     streaks half way up the wall and these seemed to vary in brightness and 
     length in seconds. Seeing was at first suspected but became doubtful 
     over this being a cause. There was also another bright streak that 
     changed brightness over 5 minute intervals (Cameron says that this is 
     not atmospheric) Apparently video was taken and confirms the effects. A 
     sketch was also made. M. Cook detected a blink with coloured filters 
     i.e. being brighter in red light (Also apparently confirmed by 
     Louderback). Estimated the north west wall was x3 brighter than 
     Censorinus. Censorinus itself varied in brightness as measured using 
     CED devices. P. Foley decided that the north was was much brighter than 
     Proclus (beyond the limits of the scale. However both Moore and Mason 
     agreed that the north wall of Proclus was very bright but shimmering 
     around in the bad seeing. They did not see any bright spots either. 
     A.C. Cook (20:18-20:44UT) confirmed that the north wall of Proclus was 
     very bright. Towards the end of the observing period the north wall had 
     faded from this maximum brightness - Cameron suspects that this might 
     have been as a result of an eyepiece misting up. The TLP was also 
     observed by Foley (Maidstone, Kent, UK) and he reported: "Bright spot 
     on north wall, Moon blink reaction". A BAA Lunar Section report with 
     extracts from the 2006 Cameron catalog. Cameron 2006 catalog ID=315 and

     On 1987 Nov 28 M. Cook (Frimley, UK) found Censorinus varied in 
     brightness as measured using CED devices. P. Foley decided that the 
     north was was much brighter than Proclus (beyond the limits of the 
     scale). However both Moore and Mason agreed that the north wall of 
     Proclus was very bright but shimmering around in the bad seeing. They 
     did not see any bright spots either. A.C. Cook (20:18-20:44UT) 
     confirmed that the north wall of Proclus was very bright. Towards the 
     end of the observing period the north wall had faded from this maximum

     On 1979 May 04 at 21:30-22:00UT Coates detected a star-like point 
     inside Hipparchus L crater using averted vision. Cameron in her 2006 
     catalog extension comments that Hipparchus L is a highlands impact 
     crater with a rille on the western ejecta blanket. The crater is the 
     smallest one in a chain that are sequenced to be half the size of the 
     previous crater in the chain. Apparently the largest crater in the 
     chain is Hind with a largely landslide covered floor - although on the 
     south is a dome? with a summit crater. Cameron's 2006 catalog extension 
     gives this TLP an ID of 51 and a weight=2. The ALPO/BAA weight=2.

     bright points about 5 magnitudes brighter than any other part of the 
     Moon. The Alpine valley points directly between these two points. "Came 
     from apparently featureless area. Both points about the same size, but

2024-Feb-17 UT 21:18-22:57 Ill=63% Chacornac observed by Khachatryan_S on 2009-8-28

     On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan, 
     Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10-
     best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac 
     area a series of fiery sparks (dot like with tiny rays), slightly 
     elongated with the multitudinal rays orientated towards the south west 
     direction. The colour was mostly red, with some yellow. The final flash 
     was the most clear. The TLP was tiny in area, but "was distinctly 
     bright against any other object on the Moon". The positional 
     uncertainty of the location of the spark effect was approximately +/-
     150 km, based upon an examination of an atlas afterwards. Just prior to 
     the spark effect, something dark, small and fuzzy (only just discrnable 
     to the eye, through the eyepiece) was seen to pass from the west across 
     the Moon in a slight curve, round the surface of the Moon to the east 
     (post observation estimate: seen for 3.5 sec and covered roughly 8% of 
     the lunar diameter in that time). The area of the dark object was 
     comparable in size to (or slightly less than?) craters such as 
     Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the 
     limits of vision of the scope used. The location of the flash was not 
     exactly at the same location as the dark object passed across, but gave 
     the impression of starting from it? A back of the envelope calculation 
     of the lunar diameter covered in the time quoted gives an approximate 
     speed (at the lunar distance) of 80km/s or on the very high end of 
     typical meteor streams that pass by. At closer distances, and 
     recalculated velocities, it is unlikely to be a satellite in low Earth 
     orbit (20m/sec at 100km distance), but could perhaps be a bird or 
     insect at a few km range? So was this dark object something in our
     atmosphere by chance passing across the field of view close to the time 
     of the TLP flare or was at the lunar distance and related to the TLP? 
     Incidentally, no attempt was made during this observation to move the 
     scope to check that the TLP remained stationary against the Moon. The 
     ALPO/BAA weight=2.

     checking out repeat illumination condition appearence for Tycho 
     concerning LTP #468 in the 1978 Cameron catalog. Did not see the 
     effect from the original TLP report, but did see, immediately at 
     looking at Tycho a very faint hint of redness in a pencil thin 
     arc (< 1/4 circumference of the rim) confined to the top of the 
     rim of the well-lit north east wall. Coloured arc similar in 
     thickness to Rupes Recta, but not as sharply defined. The outer 
     (E) edge was perhaps sharper than the inner edge. The redness 
     was more on the inside of the top of the rim. The outside of the 
     rim was bright white. This effect was seen in three different 
     eyepieces, at 311x, 224x and 400x. Checked for the effect on 
     other craters nearby but could not see this effect anywhere 
     else. The colour had dissapeared by 01:02UT. The fade took about 
     1-2 minutes. Observation of Tycho continued until 01:06UT, but 
     all seemed normal. Quick checks were made again on Tycho

     On 1980 May 23 at UT21:14-22:18 G. Blair (Bridge of Weir, 
     Scotland, UK, 216mm reflector, seeing II-IV) found a red tinge 
     along the western wall of Coperncius, perhaps 32km in length. 
     This was invisible in a blue-green Wratten 44a filter, but was 
     unmistakble in a red Wratten 25 filter. Could have been 
     spurious colour - but no other regiosn were affected. The

2024-Feb-18 UT 22:59-00:52 Ill=73% Copernicus observed by Horner_E on 2012-9-24

     2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury, 
     UK, 15cm reflector) observed a prominent red arc where the 
     sunlit part of the interior wall met the shadow. Sometimes the 
     arc was 1/4 the way around the interior, and sometimes half of 
     the way around. Telescope moved, but the red arc stayed where 
     it was. Eyepieces change, but the effect remained. Other parts 
     of the Moon checked, but no red seen. There were however 
     splashes of green e.g. Longomontanus on the terminator, 
     elsewhere further inland from the termionator, and little 
     splashes of green on Mare Frigoras - but lasting a brief time. 
     The red colour was as strong as a red LED and the green similar 
     to that of the northern lights. The observer's husband was asked 
     to independetly check Copernicus and remarked that he could see 
     a little bit of green at the top and some red near the bottom, 
     along the line of the internal shadow. Although there were 
     checks for red elsewhere on the Moon and none were seen, the 
     Moon was starting to get low and it is typical of spurious 
     colour in a few respects. Therefore the ALPO/BAA weight=1 for 
     safety.


2024-Feb-18 UT 23:06-00:27 Ill=73% Tycho observed by Blair_G on 1980-5-23

     On 1980 May 25 at UT 22:18 G. Blair (Bridge of Weir, Scotland, 216mm

     north of Tycho's north wall. Nothing more seen. ALPO/BAA weight=1. 


2024-Feb-18 UT 23:18-00:39 Ill=73% Aristarchus observed by Foley_PW on 1980-5-23

     On 1980 May 23 at UT22:30 (P.W. Foley (Kent, UK, 10" reflector, seeing 
     II) described Aristarchus as a "blue luminous patch", but it was too 
     faint to obtain a CED brightness measurement. Cameron 2006 catalog ID=

2024-Feb-18 UT 23:21-00:33 Ill=73% Copernicus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, x90, seeing conditions: "at,. boiling") noted a coloured 
     area on the west wall of Copernicus that was unusual in appearance - 
     however other craters along the terminator had a similar effect. There 
     was also a "dazzling bright spot on the E. rim and he witnessed 6 
     flashes from the lighted part of Copernicus over a very short time 
     interval. Cameron comments that the colour may well have been dur to 
     chromatic aberation because a refractor was used. The Cameron 2006 
     catalog ID=408 and the weight=0. The ALPO/BAA weight=1.


2024-Feb-18 UT 23:21-00:33 Ill=73% Proclus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. 
     bright interior uniform gray". The Cameron 2006 catalog report is 
     slight unclear as the description for thnis 1990 Aug 30 TLP also 
     includes Copernicus and Censorinus in the list of TLP craters. So one 
     description which might refere to Copernicus, could possibly have been 
     meant for Proclus, namely: "Dazling bright spot on E rim. Rotated 
     eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog 
     ID=408 and weight=0. The ALPO/BAA weight=1.


2024-Feb-18 UT 23:49-01:42 Ill=73% Mons_La_Hire observed by Geisel_M on 1972-11-15

     Mons la Hire 1972 Nov 15 UT 09:45-10:18 M.Geisel (Brisbane, 
     Australia, 12.5" f/8 reflector, x90) discovered the TLP, P. 
     Anderson (9.5" reflector) independently confirmed that the TLP
     had an effect in his Moon Blink device - but the effect 
     (suspected that the blink was caused by the extreme nrightness 
     of the mountain?) was weak and thought it not worth further 
     investigation. Photographs taken by Anderson. Geisel believes 
     the effect to be real and states that the area remained sharp 
     and clear throughout. ALPO/BAA weight=2.

2024-Feb-19 UT 16:55-16:56 Ill=80% 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.

2024-Feb-19 UT 16:55-18:16 Ill=80% 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=

2024-Feb-19 UT 16:55-18:16 Ill=80% 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.

2024-Feb-20 UT 00:12-02:05 Ill=82% Copernicus observed by Johnstone_GH on 1954-11-6

     Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT 
     20:00 (according to Cameron), but 02:00-04:00 according to the
     original observation and at colongitudes 34.7 to 35.7 deg. 4" 
     reflector, x150 used. The obsewrver reported that the western part 
     (about 1/3rd of the interior) was pitch black with shadow. However 
     there was a zone about as wide, or perhaps only a fourth of the total 
     width that was distinctly a lighter bluish shade, almost like twilight. 
     The shadows of the peaks on the western edge of the rim were clearly 
     seen crossing this bluish shadowed area. Then this area ended sharply, 
     and the farside was bathed in light from the rising sun. The shadows of
     the peak were sharply defined across the twilight zone, and the edge of 
     the pitch black shadow was easily defined but not as sharp as the
     darker shadows crossing the the blue twilight zone. The observer 
     checked other craters but did not see this condition in any of them - 
     they all had the abrupt division between black and white that we would
     normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

     of the crater to be indistinct. Elsewhere in the crater everything was
     sharp. The effect was still seen at 21:42UT, but less strong. A check
     was made for colour with aq Moonblink device, but none was seen. There
     was still a trace of this effect at 21:44UT, although detail was now
     becoming visible. By 21:48UT vertical streaks were seen crossing
     the floor from the obscuration area and these were more visible in the 
     red filter and not in the blue. Cameron comments that undefined patches
     on the floor of Plato are not normal. By 21:55UT some craterlets on the
     floor started to become visible and the TLP for Moore ended by UT22:23.
     P.Foley was alerted by Moore and saw a "amssive dense obsecuration
     on the south wall, south floor and south outer glacis to the Mare".
     Foley noted that by 21:50UT the effect was fading and finished by 
     22:03UT. Foley reported an orange translucent haze covering half of the 
     floor, but floor craterlets could be seen on and off - however his 
     atmospheric seeing conditions were IV. At 22:00 UT Foley reported the 
     floor close to the north wall to be "milky or misty". No detail was 
     visible at 21:15UT and variability in the floor continued until 
     23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference 
     between red and blue views of the area, however he did find that the 
     south rim was indistinct although this effect had lessened by 22:00 UT 
     and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at 
     21:20 UT, whereas he normally would have expected to see craterlets. 
     Mobberly was alerted at 21:40 UT and took some colour photos. He also 
     made sketches that showed variability in the floor and dark lines and 
     patches in the north west corner. However the altitude of the Moon was 
     low. Cameron mentions that two of the photos show loss of detail at the 
     south wall and beyond.and also a change in the floor markings.The north 
     wall at 21:50UT was strangely reddish (didn't think this was spurious 
     colour). The rest of the wall was sharp at 22:20UT through a yellow 
     filter. Large bright patch in the centre and rest of the floor was 
     apparently of the same shading as Mare Imbrium. The above notes are 
     based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.
     ALPO/BAA weight=2.

2024-Feb-20 UT 02:26-04:39 Ill=82% Plato observed by Brook_C on 2006-2-8 *

     C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
     dark patches coming and going (in terms of visibility) on the floor of 
     Plato. Occasional views of the central cratelet (seen as a white spot) 
     were glimpsed. The dark patches seen lasted about 1-2 seconds before
     fading out during each visibility cycle. Teneriff Mountains were 
     checked but no sign of seeing effects that might explain the dark floor
     patches. By 20:26UT the dark patch effect was fading and by 20:31UT 
     floor detail was visible. Observations ceased at UT 20:34. Seeing 
     conditions were II and the Moon was at a high altitude. Other observers 
     were alerted but came on-line after the effect had finished. ALPO/BAA 
     weight=2.

2024-Feb-20 UT 16:57-18:33 Ill=87% Plato observed by Mobberley_M on 1982-6-2 *

     Plato 1982 Jun 02 UT 22:00. Mobberley could not see the 
     central craterlet on the floor of Plato tonight. Foley notes 
     that he could only just see the central craterlet on nights of 
     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All 
     three observers compared the Plato area to other areas for 
     reference. All the above seems normal, apart from the floor
     being brighter in the green filter. Cameron 2006 extension

     On 1982 Apr 04 at UT 23:30-00:25 P. Madej (Huddersfield, UK, 7cm 
     refractor & 16cm reflector) noticed the TLP in his refractor 
     first of all at x25. So stepped up the magnification to x111 and 
     found the crater brightness not what he was expecting. He tried 
     different filters but found no difference in brightness. With 
     the 16cm reflector however some changes in brightness were 
     dected. The crater has a very pale yellow colour and it was 
     slightly darker than Lacus Somniorum. P. Foley tried to confirm 
     at 00:09 but the crater looked normal then. The Cameron 2006 
     catalog extension TLP ID is 167 and weight=3. ALPO/BAA weight=2.

2024-Feb-21 UT 00:01-03:57 Ill=89% Aristarchus observed by Armitage_J on 2006-2-9 *

     Observer noted a bright spot on the interior west wall that seemed
     brighter than what they would have expected. unfortunately the precise
     time of this observation was not recorded so the moon-rise and

     On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" 
     reflector, x159) observed an "anomalous black bar across Aris. Nearly 
     digonal to terminator." The nearby crater Prinz had curious shadow 
     patterns, perhaps related to the rising sun projecting shadows from the 
     eastern rim and "reflected down"? "At 0224 W wall had a break in it & a 
     diffuse glow where it should not be. Manske thinks it was Earthshine 
     effect. At 0305 Weier saw Manske's bar - with diffused light and 
     flicker like an aurora - like a gas with electric charge. At 0325 saw a 
     strange glow in Aris. but may be due to atm. though thought it to be a 
     LTP. Darling had never seen such effects before (flickering implies a

     (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, 
     x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 
     25. The illuminated west crater wall stood out brilliantly in blue 
     light, much more so than in white light. This was true also of 
     Aristarchus. Red light did not increase contrasts in Herodotus any more 
     than they were in white light. Shadows in Herodotus appeared as black 
     as the night west of the terminator and remained that way throughout 
     the observing period. No TLP seen in Herodotus tonight. A possible TLP 
     was seen to the west of Herodotus near the terminus of Schroters 
     Valley. It was noted at the beginning of the observing period that 
     there were four very bright spots of light, one near the end of 
     Schroters Valley, the other three grouped together a little farther 
     north. Although not far from the terminator they were definitely east 
     of it. It was noted that all of them nearly vanished in the Blue 38A 
     filter while Aristarchus and the rim of Herodotus gleamed brilliantly. 
     At 5:19UT it was noted that the most brilliant of the four lights, the 
     one near the terminus of Schroters Valley, had faded almost to 
     invisibility in white light. When first seen it had been brighter than 
     Aristarchus. It remained very dim after this through the remainder of 
     the observing period, and was unchanged at 7:35-7:49UT when I again 
     examined the area. The other three bright spots remained brilliant and 
     unchanged."

2024-Feb-22 UT 01:18-03:14 Ill=94% Aristarchus observed by Foley_PW on 1984-1-15

     Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore 
     (Sussex, UK) saw the wall as normal. However Cameron points out that 
     Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely 
     (Covington, UK) at 22:10 UT noticed a brightening on the East wall and 
     at 01:10-01:25 UT suspected that the interior had a weak yellow-green 
     cast to it. Cook (Frimley, UK) states that orange colour was within the
     interior crater, but green beyond the east rim at the 9 O'Clock and
     the south east corner to floor blue/mauvre beyond the northern rim 
     NW/WSW. Foley sstates that orange and blue/mauvre might be spurious 
     colour, but green one cannot get this way. Cameon suggests chromatic 
     aberatons as a possibility but thinks that the observers concerned were 
     experienced enough to recognize this if it were the cause. Cameron 2006 
     catalog extension ID=239 and weight=0. Moore used a 15?" refletor and 
     Foley used a 12" refletor. Mosely experienced II seeing and good

2024-Feb-22 UT 17:48-19:36 Ill=97% Plato observed by Foley_PW on 1978-8-16

     Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
     the floor beneath the north wall, and the area over the north
     wall were indistinct (almost out of focus). Despite looking
     elsewhere in the crater and surrounds, no other blurring
     (obscuration of detail) could be seen, indeed everywhere else
     was sharp and detailed. Foley tried several eyepieces but this
     made no difference. He used a crater extinction device but
     found no variations in brightness. There was a slight
     darkening when he used a red filter in the Moon Blink device.
     The obscuration effect weakened between UT20:56 and 21:10,
     was difficult to see at 21:13 and had finished by 00:15.
     Patrick Moore (12" reflector, Dublin, Ireland) saw nothing

2024-Feb-22 UT 17:57-19:11 Ill=97% 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.

     It appeared like the fluttering of a bird and passed over the 
     Moon before it evaporated, and must have been foreshortened,

2024-Feb-22 UT 18:56-20:43 Ill=97% Aristarchus observed by Louderback_D on 1985-12-25

     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.

     Aristarchus normal in red and blue filters however the
     Cobra Head part of Schroter's Valley was brighter in blue.
     Indeed it was very dull in red - Louderback says that this
     was not surprising as the whole areas around Aristarchus is
     brighter in blue. Louderback is an experienced observer

     lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in 
     Brighton. Atmospheric conditions may have made this difference, or the 
     lights may have run up and down a scale from 4 to 28. As to 
     independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this 
     display, that only the fixed, charted points so shone, and that other 
     parts of the crater were not illuminated, as they would have been to an 
     incidence common throughout.(30) In Pratt's opinion, and, I think, in

2024-Feb-24 UT 19:30-20:10 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

     On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, 
     seeing=II) found that the inner bands of Aristarchus were hard to see, 
     this was odd because the seeing conditions were good and he usually

     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

2024-Feb-24 UT 20:29-21:17 Ill=100% 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.

2024-Feb-25 UT 00:44-02:32 Ill=100% Aristarchus observed by Porter on 1978-8-19

     On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 
     6" reflector, Seing = 6/10) noticed blue on the north east corner of 
     Aristarchus and an orange glow on the south east wall. They detected no 
     movement or change in brightness. The observer used both eyes, to make 
     sure it was not an eye defect, and three filters: red Wratten 25, blue 
     Wratten 82 and Violet Wratten 47. Porter found that the colours faded 
     for a duration of 5 minutes and then returned. Their right eye gave a 
     good view and using their left eye they suspected that it was 0.5 steps 
     brighter than the remainder of the crater. The suspected colour 
     remained visible, even under moments of good seeing conditions. The 
     colour eventually faded over time and was eventually gone. Porter 
     reportd seein gcolour here on the following night. Apparently other 
     bright spots showed no colour. Fitton suggests that the filters used 
     confirm that the south east wass was definitely red in colour. The

     On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) 
     noticed a lack of detail in the Cape Agarum area - he would normally 
     have expected to have seen some craterlets. However he would not rate 
     this observation much because the seeing was only III and he does not 
     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.

2024-Feb-26 UT 04:45-05:02 Ill=98% Aristarchus observed by Cook_MC on 1990-12-3

     On 1990 Dec 03 at UT23:00-01:30 M.C. Cook (Frimley, Surrey, UK) noticed 
     that the central peak of Aristarchus was quite bright and extended to a 
     circular region in the east in the crater "sprout" area - Cameron 
     suggests that this is Bartletts self defined EWBS area?. Beyond the rim 
     to the east was very bright. However no colour effect was seen in 
     filters. A sketch was supplied. Cameron notes the coincidence of 
     perigee and full Moon. The Cameron 2006 catalog ID is 416 and the 
     weight=3. The ALPO/BAA weight=1.

2024-Feb-26 UT 21:57-23:03 Ill=95% Aristarchus observed by Pedler_J on 1990-1-13

     On 1990 Jan 13 at UT 22:15-23:05 J. Pedler (Bristol, UK, seeing=III and 
     transparency=excellent, no spurious colour) detected a blue region on 
     the north of Aristarchus, varying in sharpness/diffuseness. The crater 
     rim in this region could not be descerned. Eleswhere the crater rim was 
     normal as too were other features. When a Moon blink device was used, 
     no colour blink was detected, however through the blue filter the 
     suspected area was bright and the crater rim indistinct. Whereas 
     through the red filter the area looked perfectly normal. At 22:30UT the 
     effect had vanished and everywhere was normal. The Cameron 2006 catalog 
     ID=388 and the weight=5. The ALPO/BAA weight=3.

     the northern half of Aristarchus was "2x>" than the southern half of 
     the crater. There were two white patches of apron material near to the 
     crater Herodotus that were 50% of the brightness of the southern half 
     of Aristarchus. Furthermore the southern half of Aristarchus had a 
     circle - "dull patch on inner S wall with a bright point shining 
     through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and

2024-Feb-29 UT 03:57-04:43 Ill=82% Aristarchus observed by Haas_W on 1957-10-13

     Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978 
     NASA Catalog is supposed to have seen a bright spot of light -- 
     "explosion" in this crater. Confirmation of activity
     in Aristarchus - Three independent observations within 4 hours.
     Cameron 1978 catalog weight=5 and TLP ID No.=676. Private
     comunication with Haas shows that he recorded nothing unusual
     on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has
     been given until this matter is cleared up.
