2023-Nov-01 UT 00:57-01:17 Ill=88% Aristarchus observed by Moore_P on 1982-7-9

     On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"? 
     reflector, seeing III) found that Aristarchus was very bright 
     and slightly blue. Cameron comments that Moore's eyesight is not 
     very blue sensitive. The Cameron 2006 catalog ID=175 and weight=
     4. The ALPO/BAA weight=2.


2023-Nov-01 UT 00:57-01:17 Ill=88% Grimaldi observed by Moore_P on 1982-7-9

     On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector, 
     seeing=III) found that Grimaldi A was the 2nd brightest feature on the 
     Moon, and that there was colour detected with a Moon blink device on 
     the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight=
     4. The ALPO/BAA weight=3.


2023-Nov-01 UT 20:26-22:04 Ill=81% Macrobius observed by Gray_R on 2005-10-21

     On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9 
     refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP 
     in Macrobius. His report is as follows: "Blinked Macrobius with Wratten 
     Filters Blue 38A and Red 29. Macrobius became almost invisible through 
     the Blue 38A and essentially the same as in white light through the Red 
     29. The interior of the crater was completely in shadow. The only part 
     of the east wall that was visible was an apparent high point still in
     the sun and seen as a bright point of light. This faded into darkness 
     before 13:56UT. No sign of any illumination of the east wall crater 
     interior or the interior of the west wall was seen during the
     observation period. The outer west wall was a rough looking, 
     complicated mix of deep shadow and illuminated sunlit terrain." The 
     observer concluded that there was not a TLP - although he did get a 
     filter reaction, this may have been due to the different densities of 
     the filters? ALPO/BAA weight=2.


2023-Nov-01 UT 21:55-22:29 Ill=81% Macrobius observed by Goodacre_W on 1898-12-31

     Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End, 
     England, 12" reflector) "Interior nearly filled with shadow at sunset. 
     Inner E.wall very bright-a distinct penumbral fringe to black shad. 
     cast on it from W.wall. Seen best using high powers. (Firsoff & MBMW 
     give date as just 1895 but must be wrong-phase - see  app.ref.)" 
     NASA catalog weight=4 and catalog ID #304. ALPO/BAA weight=2.


2023-Nov-01 UT 23:06-00:28 Ill=81% Proclus observed by Lucas_M on 1989-8-20

     On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye) 
     witnessed a "pin-point flash" in the middle of the lower right quadrant 
     of the Full Moon. Foley suspects that this was in the Proclus region? 
     The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA 
     weight=2.


2023-Nov-02 UT 01:51-03:14 Ill=80% Copernicus observed by De_Groof on 1989-1-26

     On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second 
     long flash from Copernicus crater. The Cameron 2006 catalog ID=347 and 
     weight=3. The ALPO/BAA weight=3.


2023-Nov-02 UT 02:20-03:14 Ill=80% Aristarchus observed by Maley on 1969-9-30 *

     Aristarchus 1969 Sep 30 UT 04:46-05:10 Observed by Maley, Saulietis 
     (Houston, TX, USA, 16" reflector, x130) "Intermittent blue color on SE 
     wall, verified by others. At 0500h, taking 10s to reach max. then 
     slowly disappeared. Gap appeared after 1st event. Drawing." NASA 
     catalog weight=4. NASA catalog ID #1202. ALPO/BAA weight=4.


2023-Nov-02 UT 21:21-21:31 Ill=73% Fracastorius observed by Amorim_A on 2022-4-21

     Fracastorius 2022 Apr 21 UT 01:35-02:12 A. Amorim (Brazil - 
     90mm f/10 refractor, 25 & 10mm eyepieces ) observed visually a 
     little bright spot near the centre of the otherwise completely 
     shadow filled crater. The bright spot was surrounded by a coma 
     effect. Clouds intervened but by 02:12 the spot was no longer 
     visible, just a thin patch of light close to the crater's 
     centre. Observations started when the Moon's altitude was 15 
     deg and ended when it was 23 deg above the horizon. ALPO/BAA 
     weight=1. 


2023-Nov-02 UT 22:05-00:01 Ill=72% Aristarchus observed by Louderback_D on 1991-7-31

     On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" 
     refractor) observed that the south floor of Aristarchus was wellow - 
     "almost gold, spilled over S wall on ray toward Herodotus". Cameron 
     comments that Bartlett often reported a yellow floor but not a spill of 
     the colour over to the external ray. Cameron also comments that 
     Louderback's refractor would refract more in blue light than in yellow, 
     therefore she did not think that it was due to chromatic aberation. The 
     Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2. 


2023-Nov-02 UT 22:05-00:01 Ill=72% Mons_Piton observed by Louderback_D on 1991-7-31

     On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" 
     refractor) found that all of Mons Piton was "unusually dark". Points D, 
     C (E and S resp), usually brightest points, but this time were not 
     bright. "Whole mt was as dark as W wall usually is at this time. In 
     violet filter Piton disappeared completely, but was a little brighter 
     in red filter and points D & G showed. Color not seen by eye. No albedo 
     measured. Suggests red event." Cameron rules out chromatic aberation 
     from Louderback's refractor. The Cameron 2006 catalog ID=431 and the 
     weight=3. The ALPO/BAA weight=1.


2023-Nov-04 UT 02:21-02:36 Ill=62% Plato observed by Foley_PW on 1975-6-29

     Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12" 
     reflector, seeing, III, good clarity transparency). At 23:05, 
     blue was seen on the inner wall:floor southern boundary, and red 
     on the corresponding northern floor:wall boundary. However by 
     00:30, blue was now on the W floor:wall boundary, and red on the 
     E floor:wall boundary. Atmospheric spectral dispersion existed 
     in many regions, but did not change like the colours in Plato. 
     Similar appearance craters such as Grimaldi, Schickard, and 
     Riccioli, were checked for a similar change in colour, but no 
     change was noticed in these. ALPO/BAA weight=1.


2023-Nov-05 UT 00:02-01:08 Ill=53% Plato observed by Moore_P on 1991-12-28

     On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on 
     the floor of Plato crater. This report needs to be read in context with 
     the comments by Cameron for A.C. Cook's observation of the floor of 
     Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.


2023-Nov-05 UT 02:23-03:13 Ill=52% Pitatus observed by Unknown_Observer on 1974-6-12

     On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the 
     northern edge of the floor of Pitatus crater. 


2023-Nov-05 UT 23:40-02:51 Ill=43% Earthshine: sporadic meteors

2023-Nov-07 UT 02:06-03:14 Ill=34% Grimaldi observed by Beaumont_S on 1998-3-22

     Grimaldi 1998 Mar 22 UT05:15-06:00 S. Beaumont (Windermere, UK, 
     127mm rich field refractor, seeing III, transparency Good) 
     observed that the northern half of Grimaldi seemed much lighter 
     than the southern half. She comments that she has seen this 
     before in last quarter phases, but it was really quite marked 
     how lighter the northern half was on this occasion. The ALPO/BAA 
     weight=1.


2023-Nov-07 UT 00:20-02:51 Ill=33% Earthshine: sporadic meteors

     USA, 4.5" reflector and 3" refractor, S=3, T=5) "Inner E. wall 6 deg 
     with very large EWBS at 8deg. No viol. color anywhere & floor was gray 
     at 4 deg (very low). C.p. is only 8 deg. At base of c.p. between peak & 
     advancing shadow a very faint but definite red glow was seen. It was 
     also seen later in the 3" refr. Was confined to W.base of peak & no

2023-Nov-09 UT 02:08-03:14 Ill=17% Aristarchus observed by Schmidling on 1964-6-6

     On 1964 Jun 28 at UT 08:20-09:10 Schmidling, St Clair, and Platt 
     (Riverdale, New York, USA, 8" reflector, x256) observed in the 
     Aristarchus, Herodotus, Schroter's valley area: two red spot glows, 
     glimmer, looked like ruby gems. Cameron says that the date was 
     predicted by Greenacre and looked for. The Cameron 1978 catalog ID=817 
     and weight=5. The ALPO/BAA weight=4.

     On 1985 Apr 23 at UT20:00 Smith (England, UK) found two large glows in 
     Earthshine, one was somewhere in the vicinity of Gruithuisen (i.e. 
     between Aristarchus and Sinus Iridum). The Cameron 2006 catalog ID=263 
     and weight=1. The ALPO/BAA weight=2.

2023-Nov-16 UT 16:28-16:41 Ill=12% Promontorium_Laplace observed by Ashton on 1989-2-9

     On 1989 Feb 09 at UT 19:00 Ashton (Stafford, UK, seeing=V) observed a 
     "green glow in the "peninsular region" of Cape La Place (south of poss. 
     Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12" 
     reflector) noticed a "pin point glow surrounded by blue-green halo" 
     through a blue filter, but not seen through a red filter. He also 
     suspected some brightness variations. He noted that Aristarchus was 
     barely seen and Copernicus was only a faint smudge, presumably because 
     of the bright limb? J. Cook (Frimley, UK) observed a white glow in the 
     Cape region (made up of pin points?) - no other places had a similar 
     effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing 
     unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found 
     a "bright point source near the tip of LaPlace perhaps maupertius D (or 
     LaPlace D?)." This was seen in a blue filter but not through a red 
     filter - the limb was also seen as bright and the cape as a faint 
     patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although 
     commenting that Aristarchus was a bit dull, could not see the Sinus 
     Iridum glow, North (UK) could only detect the vague presence of 
     Earthshine throug his finder scope, but not in his telecope. The 
     Cameron 2006 catalog ID=349 and the weight=2. The ALPO/BAA weight=3.

     On 1989 Feb 10 at UT 18:15-18:40 Holmes and Wooler (Lancashire, 
     UK, 22cm Newtonian, x155) found Aristarchus to be bright, but so 
     too was Prinz. However in a 2nd observing session at 21:05-21:10 
     an area near crater both regions werestill visible but fainter.

2023-Nov-17 UT 17:00-17:43 Ill=20% Proclus observed by Edmonds on 1989-2-10

     On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a 
     "bright red coppery" colour in the northwestern part of 
     Proclus crater. He checked and found that there was no colour 
     elsewhere, though he still suspects that the effect was 
     spurious colour. Cameron comments that usually blue 
     is seen in the north and red in the south if due to spurious 
     colour. The Cameron 2006 catalog ID=350 and the weight=3. The 
     ALPO/BAA weight=1.

2023-Nov-18 UT 17:04-17:54 Ill=30% Aristarchus observed by Miles_H on 1985-4-25

     On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed 
     Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had 
     observed it one hour prior to Miles and found it to be both dull and 
     blue - with a bright patch west of the crater on Aristarchus Upsilon 
     Mountain. At 21:45UT 6 star-like flashes seen on the floor. They 
     occurred again a few minutes later and repeated at 22:04UT.By 21:45UT 
     the bright patch had gone though. Smith (England) had also apparently 
     seen the flashes and a further glow, albeit more north of the one seen 
     by Foley. Miles confirmed Smith's glow north of Aristarchus. 
     Peters did not see much, indeed found Aristarchus to be quite 
     faint (2130-2141). The Cameron 2006 catalog ID=264 and the 
     weight=3. The ALPO/BAA weight=2. 


2023-Nov-18 UT 17:04-17:54 Ill=30% Torricelli_B observed by Cook_MC on 1985-4-25

     Curious lack of detail, but this may have been related to
     the seeing. Of greater interest though was a dark blue
     splodge where the crater should have been. Shadow seen through
     this splodge, but no crater rim seen.


2023-Nov-18 UT 17:07-18:44 Ill=30% Aristarchus observed by Cook_JD on 1981-3-11

     A faint white pinpoint flash seen and also in the same position
     a whitish glow around the crater. No futher flashes seen after the
     first one. From UT2117-2130 the glow was still visible but faded
     making it more difficult to locate. When Foley observed he found 
     Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
     and several other features being visible. Both observers used
     12" reflectors. Cameron's 2006 catalog Extension ID=124 and 
     weight=0. ALPO/BAA weight=3.

     Webb (England, using a fluid achromat) saw brilliant minute spots and 
     streaks in Mare Crisium dotting its surface. This was seen near first 
     quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall 
     had all seen it this way at times. Cameron 1978 catalog iD=111 and

     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.

2023-Nov-19 UT 18:35-19:43 Ill=42% Plato observed by Schroter on 1789-9-26

     On 1789 Sep 29 at UT04:25? Schroter (Lillienthal, Germany) noted 
     1'18.5" south east of plato was a whitish bright spot shining somewhat 
     hazily, 4-5"in diameter and at 5th magnitude. He never saw this again. 
     The spot became conspicuous at times and then disappeared. There was 
     nothing else similar in Earthshine. Note that the year might have been 
     1788? The Cameron 1978 catalog ID=50 and the weight=3. The ALPO/BAA 
     weight=3.


2023-Nov-19 UT 18:45-19:43 Ill=42% Mare_Crisium observed by Schroter on 1789-9-26

     Schroter, from Lillenthal in Gemany, in 1789 (possibly it was 
     1788) Sep 26 UT 04:30 saw a small nebulous bright spot on the 
     northern edge of Mare Crisium. Cameron 1978 catalog ID=50 and

2023-Nov-20 UT 15:21-15:24 Ill=52% Mons_Piton observed by Marshall_KP on 1983-5-20

     On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) 
     noted that Mons Piton was too bright near the terminator and was 
     surrounded by shadow. A sketch was made. The mountain appeared 
     segmented with one thin shadow line. The mountain looked like a 
     Mexican Sombrero hat. This appearance is normal. What was 
     abnormal was that Piton was brighter than Proclus, and only 
     slightly fainter than Censorinus. The CED brightness 
     measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
     3.7. Please check to see whether this is still the case. The

     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

     On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar 
     freflector) observed an occultation of Kappa Aquari, a wide double 
     star, on the western limb. The star faded perceptably before 
     disappearing. Cameron says that the fact that the star was a double was 
     not an explanation - she says that there are many reports of similar 
     fades for single stars. The Cameron 1978 catalog ID=1384 and weight=4.

2023-Nov-21 UT 15:21-16:06 Ill=64% Eratosthenes observed by Hill_H on 1947-1-30

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


2023-Nov-21 UT 18:04-19:24 Ill=64% Tycho observed by Spellman_R on 1996-4-27

     1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA)
     " 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow, 
     topmost section of the central peak was in sunlight. In white light 
     brightness of the central peak rivaled the brightness of the Eastern
     (sunlit) wall. No change was detected in red light, however in blue 
     light definite strong darkening was observed. Blink obtained when 
     viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair 
     seeing the apparent size of the central peak in white and red light was 
     the same, in blue light the central peak in white and red light was the 
     same, in blue light the central peak size shrank to 1/2 white and red 
     size (and brightness). Also appearing sharper. Comparison was made also 
     with the central peak of Alphonsus, no changes were observed. The 
     significant part of the observation was the relative brightness of the 
     central peak to the sunlit rim in white and red light, they appeared 
     almost identical with the crater rim, being just slightly brighter. In 
     blue light the brightness of the central peak was reduced by at least 
     half while the rim brightness was not, (relative to one another). I 
     strongly believe that this was a real event. The shadow filled 
     portion of Tycho was examined for any abnormalities but none 
     were observed. Observations were ended shortly after 3:14 U.T. due to 
     clouds. I also conducted about 20 Moon blink observations during this 
     observing run and got the same strong reaction each time." ALPO/BAA

     25cm reflector, x250 & x380, seeing good but with some cloud)
     The interior W. wall of this crater (on the lip) appeared 
     hazy - difficulkt to bring detail into focus. Neighbouring 
     craters/detail were sharp. Details in the crater wall interior

2023-Nov-22 UT 18:34-20:26 Ill=75% Mare_Imbrium observed by Caruso_J on 1979-8-3

     A region of the Mare Imbrium was extremely bright, giving
     a reading of 8 out of 10 on the Elger scale. Cameron notes
     that from photos of the Full Moon, the area appears to
     normally be the brightness of Archimedes floor i.e. 3.5 out
     of 10 on the Elger scale. Atmospheric seeing was excellent
     and the observer could see a lot of fine detail with their

     cloud after the impact over a duration of 9.5 minutes. This 
     was near to Deslandre crater. 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%

     (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5,

     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."

     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

     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.

     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.

     Cobra Head part of Schroter's Valley was brighter in blue.
     Indeed it was very dull in red - Louderback says that this

     brighter in blue. Louderback is an experienced observer

     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

2023-Nov-27 UT 23:04-00:42 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.

     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 
     sees them? However he did not believe that there was any obscuration 
     going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

2023-Nov-28 UT 00:32-01:31 Ill=99% Aristarchus observed by Brook_C on 2002-3-29

     On 2002 Mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor, 
     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.


2023-Nov-28 UT 00:32-01:31 Ill=99% Proclus observed by Brook_C on 2002-3-29

     On 2002 mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor, 
     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. Just as an after thought - was 
     it Aristarchus that was varying, or Proclus?


2023-Nov-28 UT 00:57-01:53 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.


2023-Nov-28 UT 18:10-19:21 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.

     On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50) 
     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section 
     circular. She comments that it might have been a meteor? The Cameron

2023-Nov-30 UT 01:04-02:27 Ill=92% Kepler observed by Corralitos on 1968-12-7

     On 1968 Dec 07 at UT 07:00? Corralitos Observatory (Organ Pass, NM, 
     USA, 24" reflector and Moon Blink device) observed a bluing around 
     three craters, one of which was Kepler. This effect lasted several 
     days. Photographs were taken that show30% more intensity in the blue 
     filter than in red or neutral. The Moon's decination was northerly. The 
     observers suspect that it was an atmospheric efect and not a TLP. The 
     Cameron 1978 catalog ID=1105 and the weight=5. The ALPO/BAA weight=3.


2023-Nov-30 UT 02:39-03:14 Ill=92% 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.


2023-Nov-30 UT 20:01-20:13 Ill=87% W_Limb observed by Pickering_WH on 1897-10-14

     In 1897 Oct 14 at UT 00"50 Pickering (Cambridge, Mass. USA, 15" 
     refractor?) observed "Refractive displacement of lunar atm. at 
     bright limb was 0.4" (time is for occultation of Alctone in 
     Pleiades)" The Cameron 1978 catalog ID=294 and the weight=3. The 
     ALPO/BAA weight=1. Note this may? refer to an occultation, in 
     which case it will be pointless to observe again for a 
     particular illumination.


2023-Nov-30 UT 20:01-20:08 Ill=87% Messier observed by Hansen on 1972-8-27

     Messier & A 1972 Aug 27 UT 08:51-09:21 Observed by Hansen (LeMoore, CA, 
     USA, 6" reflector, x200) "Perculiar thread of shadow connecting the 2 
     craters. Sun's elev. @ 6deg. Drawing (possibly a high peak on E.wall of 
     A casting a shadow?)" NASA catalog weight=1 (very low). NASA catalog ID
     #1342.


2023-Nov-30 UT 20:15-22:12 Ill=87% Plato observed by Wilkins_HP on 1944-3-12

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


2023-Nov-30 UT 20:25-21:53 Ill=87% Grimaldi observed by Firsoff on 1937-9-23

     Grimaldi 1937 Sep 23 UT 05:00 Observed by Firsoff (Glastonbury, 
     England, 6" reflector + filter) "Variations in green. Strong green on 
     this date. Other dates of variation are:

2023-Nov-30 UT 20:57-22:22 Ill=87% Birt observed by Doherty_EG on 1972-9-25

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


2023-Nov-30 UT 21:20-23:12 Ill=87% Herodotus observed by Keyes_J on 1989-12-16

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