Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca, NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency good) "I was out this morning (2:58-3:43 UT, October 14, 2002) observing Torricelli B. At 3:17 UT the west sunlit wall of the crater brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual terms it went from slightly less bright than the walls of Picard to as bright as the sunlit west wall of Dionysius. This was observed at 114x in white light, where all three craters were in the field of view simultaneously. This event lasted less than a minute and no comparable brightening in Dionysius or Picard was seen. The wall of Torricelli B returned to 5.0 in brightness. I continued to observe Torricelli B in white light until 3:43 UT, but the brightness remained at 5.0. Before the brightening I tried blinking Torricelli with the following combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue 80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more prominently in any combination except the Red 25-Blue 38A combination, where Torricelli B became invisible in the Blue, probably because of the filter density. Both the Blue 80 and Schott BG 38 seemed closer in density to the Red 25 than the Blue 38A is. I could not see any details inside Torricelli B during this session, including the bright spot on the NE rim." The ALPO/BAA weight=3.
Mare Vaporum 1969 Apr 24 UT 19:34 Observed by Bentley (England, 8" reflector, x320, S=E) "NW part of mare obscured for 4 min., gradually thinning." NASA catalog weight=3. NASA catalog ID No. 1123. ALPO/BAA weight=2.

Could see hint of knot seen before. Craters named in 7/23/88 (#319) were all normal this time too". Is it possible that this report refers to the crater "Gray" rather than "Proclus" as the column field suggests in the Cameron catalog? The Cameron 1978 catalog ID=333 and weight=5. The ALPO/BAA catalog weight=2.
On 1981 Sep 08 at UT 21:28-21:34 P.

Caruso (Middletown, CT, USA, 3" refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not visible, however Heraclides E, Helicon G, and indeed many other smaller craters could be seen. There were two small mountains in the general area of Bianchini G. and a mare ridge - all these were clearly seen. Caruso states that Bianchini G should normally be much more clearly seen than the other features mentioned and is the same size as Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3.

On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector, x300) using an English Moonblink device found colour on the south west part of the floor. Note that for the times given by Cameron, the Moon was below the horizon from California - so possibly these are local times and these times need to be correctly converted into UT? The Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector, seeing=III) found the region around the cleft on the souther rim to be out of focus - however atmospheric conditions were turbulent until 23:18UT. An unsual dark triangular region (long base against rim) was seen to extend from the inner rim at 12 o'clock onto the floor for 13- 16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK) found the south east to soth west to be obscured again, but not as badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the dark region had 2 white bands on the side and the south west wall was blurred like it was on the 20th July - this time tough colour was not present. There were also two light patches on the floor. Mosely (Coventry, UK) observed the south wall at x120 and found the wall out of focus at the 11 o'clock location. Through a yellow filter he saw a "white mistiness: on the top of the southern rim and only the south east cleft could be seen (no colour). By 22:40-23:00 the effect had cleared up. No dark triangular patch was seen. When Marshall (Surrey, UK) observed (22:30-03:00) nothing unsual was seen, though a sketch provided shows a light patch on the floor located at 11 o'clock. All observations, made by all observers had some atmospheric turbulence, however trsnparency was good. The Cameron 2006 catalog ID=225 and the weight=5. The ALPO/BAA weight=3.

Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual Appearance". NASA catalog weight=1 (very low). NASA catalog ID #182. ALPO/BAA weight=1.
On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in Gassendi - some obsevers detected colour, others did not. P. Moore did not notice anything unsual earlier at 18:50-19:00, though his seeing was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did however notice a small reddish spot to west of central ridge, but by 20:30UT the colour was less obvious, but the spot was back again at 20:45, but not easily seen at 21:00 and gone completely by 21:45UT. N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section report. ALPO/BAA weight=3.
On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector) observed pink on the outer SW rim and a red spot towards the S of this. A red spot was seen on the eastern side of Vallis Schroteri but only by Barr and Dungan. Other features checked for atmospheric spectral dispersion and chromatic aberation - but the colours in Aristarchus were not due to these. Smaller 12" scope checked but no effects seen - presumably due to resolution and image contrast issues? Pink on the SW rim may have been seen in a 69" scope by Boyce and Ford. ALPO/BAA weight=4.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5. ALPO/BAA weight=2.
On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK, 12" reflector, x200, seeing=II) noticed in the area south east of Manilius that it was brighter in red light than in blue light at 20:15UT whereas 1 minute later it was the same brightness in each filter. The effect reappeared at 20:21UT and was particularly strong at 20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was of high reflectivity in white light and was bright in red at 21:15UT, thougjh the south east area stopped giving a colour reaction at 21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT however at 23:55UT it was surrounded by a transient white ring that varied in visibility in an irregular way. Foley found Manilius B had a vivid blue interior and in blue light the ring was black. and not at all seen in red or white light. The CED brightness measurement varied from 1.9 to 2.4. All other regions observed were normal in brightness. Violet was seen on the west wall of Aristarchus though. M.Price (Camberley, UK) found a possible blink in Manilius B but was observing under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5. ALPO/BAA weight=4.
On 1891 Oct 14 at UT 18:00 Pickering, based at Arequipa, Peru, and using a 12" reflector, saw is Schroter's Valley and the vicinity "Varitions in vapor column and visibility of craterlets A, C and F (Plate B) in early period at Peru. Directional vaporjet towards F varied but was always continuous. Later, in Musa. There was a break in it. D was quiescent in early period. (due to change in telescope & atmosphere ? Time estimated from given colongitude)." Cameron 1978 catalog ID=273 and weight=3. ALPO/BAA weight=2.

There is a light spot here, but what was unusual was that the visibility decreased over time. ALPO/BAA weight=1.
Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon, UK) found that the bands of Aristarchus were clearer in red than in blue light. North found that the sunlit part of the crater was very bright. M. Cook described the crater as a "kaleidoscope of colour. Foley observed UT 23:05-01:00 (Kent, UK, Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA Lunar Section Circular. The Cameron 2006 catalog ID=190 and weight=5. The ALPO/BAA weight=3.
On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet area form on the western exterior of Aristarchus, and a less deep violet area form to the eastern edge of Aristarchus. As these were becoming stronger, a blue-like haze formed on the sunlit floor of Aristarchus, that obscured underlying detail. The ALPO/BAA weight=2.
On 1825 Jan 01 UT17:00? an unknown Russian observer noticed a cloud in Mersenius.
nr Fra Mauro 1970 Aug 14 UT 05:00? Observed by Bell (Californina). "Bright blue-white flare (meteor?)(call for obs. at Fra Mauro at perigee because of moonquakes there -- therefore biased to tidal hypothesis.

Altho. a deep shadow is normal to the W. of the cape at this period, (then cape must have a slope > 30deg!). he wondered if shad. was more extensive than usual? Prout noted a dark inky coma- shaped spot. Dundee obs. concluded it was a shadow. Took photos. Analysis of them was underway at time of rep't." NASA catalog weight=5 (very high). NASA catalog ID #1462.
On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in the south east corner interior of the crater Aristarchus. This colour was confirmed by the observers wife. By 11:21 UT the colour had faded completely. Rodway had been a lunar observer since 1958, using a wide range of instruments from 3 inch refractors to 12 inch reflectors and had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so was an experienced observer. The ALPO/BAA weight=4.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector, seeing III-IV) found that LaPlace A was significantly more prominent than usual - comparisons were made with photographs in books. The Cameron 2006 catalog ID=178 and weight=3. The ALPO/BAA weight=1.
On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a starlike flash in Alphonsus crater. The ALPO/BAA weight=2.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit around the Moon, obtained images of the Cobra Head region of Aristarchus crater that suggested a ~15x colour ratio increase (0.4 microns / 1.0 microns) in comparison with images obtained on 1994 Mar 03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting. However it was later suggested that this was due to incorrect radimetric calibration procedures being followed. The ALPO/BAA weight=1.
On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8" reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that one of his pre-designated points, called "A", through to "C and "D" was at least 5 brightness points brighter in red than in blue light. The reverse was true on Sep 25th. Tonight the red seemed to be on a narrow strip on the western edge. The Cameron 2006 catalog ID=109 and the weight=3. The ALPO/BAA weight=3.
On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a dusky dark gray area just north of Herodotus and just south of the Cobra Head. The interior shadow on the east of Herodotus by comparison wad black and distinct. No change was seen when viewed through a rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA) was observing at the same time but had better observing conditions and could see detail in this region, suggesting that it was not a TLP. There is no Cameron entry for this report. The ALPO/BAA weight=1.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi III seeing, 12.5" reflector) "Intensely bright craterlet south of central peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed the crater was highly luminous at 21:20, and surrounded by a blue halo that had a darker blue band within it. This craterlet faded over time, and by 21:20 Moore considered that it was no longer prominent, by 21:22 Foley confirmed the reduced brilliance, and by 21:30 Moore considered it to be perfectly normal. Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID= 306 and weight=5. The ALPO/BAA catalog weight=3.

The effect was still present at 20:36 but back to normal by 20:43-20:48. Amery (Reading, UK) found a possible brownish tinge on the west wall, though spuroius colour was present elsewhere on the Moon. Foley found the WSW corner darkened in blue light. Cook found pink on south rim of Bullialdus and Pedler found Bullialdus to be a confused mass with bright and dusky spots and patches - no colour seen. Cameron 2006 catalog ID=72 and weight=0.

Observations terminated by hazy cloud drifting over Moon. Observer remarked that it looked like chromatic aberation, but telescope was a reflector and no colour was seen elswehere on the Moon. Cook (Frimley, Surrey, UK) 19:48-19:55 noted red on E. rim exterior and on SE part of central peak, and blue on N. rim - strongly suspected spurious colour". ALPO/BAA weight=1.
Aristarchus 1968 Apr 11 UTC 22:00? Observed by Farrant (Cambridge, England, 8" reflector, Seeing Antonidi I (very good)) "Crater had on NE (ast. ?) wall a very pale blue color & opposite wall a pale red. No other crater showed color.

Fitton (Shaw, Lancashire, UK, 8.5" reflector, x200, Wratten 25 and 44A filters, seeing II-III, transparency, good) noticed in Aristarchus, blue to the north west (IAU?) internal wall, also blue observed in other small bright objects against dark backgrounds. Lunar rotational axis and optical normal related such that the normal runs NW-SE (IAU?) through these features. Observer deduced that the coliur was obviously spurious and no blink was seen in any feature. The blue disappeared as the lunar altitude increased and no blue seen by 00:00UT. This is a BAA lunar section observation. The ALPO/BAA weight=1.
On 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector, x286) observed that east of Lichtenberg were ëxtensive rosy areas" around the northern edge of the lava sheet. Hill believes that it may have been the same effect as seen by Madler (Germany), Barcroft (USA) and Baum's (UK) 1951 observation. The colour was "ünmistakable" and nothing to do with the atmospheric spurious colour. Other features were checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA weight=2.
On 1992 Jan 18 at UT 22:34-23:48 A.C. Cook (Frimley, UK, 8" reflector, seeing=III) was able to see 4 craterlets and two rays on the floor of Plato. This was suprising because Moore, using a larger telescope and magnification, was unable to see any detail here on 1991 Dec 12th at 02:10 - according to Cameron.

Doherty (Small Thorne, UK) 8.5" reflector, x110, x200 & x274, S=8-8.5, T=8, Moon 57 deg in alt) and 3 others, using the same instrument, saw a bright purple- blue patch in Aristarchus. Other areas checked for colour and none sen elsewhere. Attempts were made to contact observers elsewhere but with no success. Sketch made and shows the patch covering the floor area of Aristarchus and extending out beyond the east rim. Patch was elliptical in shape and the semi-major diameter was approximately 2/3rds of the diameter of Aristarchus, or about 27 km. The event lasted 5 hours and gradually faded.

Fainter than Proc., Cop., & Tycho. Others rated brightness in order-- Hell, Stevinus, Furnerius, proc.; & Proc., Tycho, Hell, Aris. Photos confirmed dimness of it. For some observers it became invis. at S=II (good). Good ranked at least 4 other craters brighter than Aris. & that at 2035h it dimmed. Earthshine cond. extraordinarily good. Peters, at S=IV (fair?) rated Aris. brightest". At 23:50UT LeCroy Jr and Sr (Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on the Moon during a lunar eclipse (including Aristarchus). At 23:50UT Aristarchus was an oval shape with no details seen. It had a ray extending from the south west rim (normal). The north rim was slightly blue and the south west rim very very slightly red. At 23:55UT it was clearing and details showed. At 00:02UT it was clear. Sketches were provided. Cameron comments that the colours fit Fitton's predictions on spectral dispersion in our atmosphere from atmospheric inversions. The brightness measued was 10+ and normal should be 9, and the plain is 4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron 1978 catalog ID=1418-1420 and weight=5 (1-0 for LeCroy report). The ALPO/BAA weight=3.
On 1989 Aug 17 at UT 01:02-04:20 G. Kolvos (Thesaloniki, Greece, 4"reflector) measured (using photometry) that although there was a gradual fade over the Moon as the eclipse progressed, there was a 2"% rise in brightness of Aristarchus.Graphs were submitted and photos. A.C. Cook supplied CCD images and CCD photometry. A photograph by Conway (Sun Prarie, WI, USA) at the start of the eclipse reveal a bright colourless spot (aparently confirmed). The Cameron 2006 catalog ID=373 and weight=5. The ALPO/BAA weight=2.
In 1921 Oct 16 at UT 22:00-00:00 Genin and others (Russia) observed during a partial eclipse that different parts of Aristarchus crater had brightness of phosphorecence. Cameron says that this is independent confirmation. The Cameron 1978 catalog ID=383 and weight=5. The ALPO/BAA weight=3.
Aristarchus 1966 Oct 30 UTC 01:32-01:48 Observed by Bartlett (Baltimore, MD, USA, 5" reflector x79, x142, x194, S=5, T=3) "S.region of floor granulated & 6 deg bright light brownish tone; rest of crater 8deg bright white". NASA catalog weight=4 (good). NASA catalog ID #992.
On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel (Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max, with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod mounted, mirror up), A series of images were taken. The 21:06 one showed a grey column cutting across the central floor of the crater from the west and then bisecting the eastern rim. All detail inside is completely invisble. Some (but not all) of the other images showed a more blurred view of this feature. It's possible that this was a seeing ripple effect, or just the natural appearance of shadings on the Moon at this time, however for now this will be given an ALPO/BAA weight of 1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade 2045 reflector, x40, seeing=turbulent) detected flashes coming from just north of the centre of Mare Tranquilitatis. Some of these flashes were of a duration of seconds whilst others were several minutes. Altogether ~20 flashes were seen, and not in the same place. "5 small star-like points could be located - and there were lots of craterlets". The spots were "lined up E-W at N of 10 deg latitude." Colour was not visible on these nor variations. Apparently the observer had seen this type of TLP before but had not reported them. The Cameron 2006 catalog ID=323 and weight=2. the ALPO/BAA weight=2.
On 1956 Nov 19 at UT 00:00? an unknown observer (Cameron gives an AGU meeting reference) apparently saw a TLP in Aristarchus crater. The Cameron 1978 catalog ID=657 and weight=0. The ALPO/BAA weight=1.

Cameron comments - "were this & No. 429 LTP or just good seeing?)." Note it is possible that she mean LTP 439 in which case it would refer to the previous nights TLP. The Cameron 2006 catalog ID=439 and the weight=2. The ALPO/BAA weight=1.

Apparently Chapman (Kent, UK) detected it easily. At 01:33UT the colour was barely visible. No TLP alert was issued because the souther edge of Mons Pico also exhibited a hint of colour, and anyway the seeing conditions were poor. Despite this no other features revealed colour. The Cameron 2006 catalog ID=446 and the weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, x260) noted that the southern slope of Mons Pico had a tint of colour. No other features revealed colour apart from Aristarcus, where a TLP was going on. The Cameron 2006 catalog ID=446 and the weight=0. The ALPO/BAA weight=1.

On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue segment on the upper limb - this was apparently confirmed by Faulkes (Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT 06:00 as Sep 07 is local time. She also infers that "upper limb" is the southern limb and that Swift was at the Lowell Observatory, Flagstaff, AZ, USA. The Cameron 1978 catalog ID=285 and weight=5. The ALPO/BAA weight=2.

On 1821 July 25 at UT 03:30 Gruithuisen (Munich, Germany) observed, near Aristarchus, some brilliant flashing spots on the Earthlit side of the Moon. These disappeared after a short while then re-appeared. The Cameron 1978 catalog ID=90 and weight=4. The ALPo/BAA weight=3.
On 1882 Nov 07 at UT 05:00 Hopkins (UK) observed the dark eastern limb and a line of light and attributed this to a lunar atmosphere. Further details can be found in: Reference: Sirius 16, 279, 1883. Cameron 1978 catalog ID=229 and weight=3. ALPO/BAA weight=2.
1877 Mar 17 UT06:45 Dennett (England) found that the S.cusp showed traces of an atmosphere. NASA catalog weight=2. ALPO/BAA weight=2.
Heywood of Wheatville, Ohio, USA, using a 2" refractor under fair seeing conditions, saw a misty light on the dark limb (similar to Cameron's 1978 catalog TLP 239). The effect had narrowed down on the 30th. Cameron comments : "old moon in new moon's arms?". Cameron 1978 catalog TLP ID=242 and weight=1. ALPO/BAA weight=1.
On 1982 Dec 18 at UT 15:00? Arsyukhin (Moscow, Russia, 3" reflector) found that the northern cusp was protruded onto the dark side as a blue thread. The Earthshine was brown in colour. The Cameron 2006 catalog ID=191 and weight=2. The ALPO/BAA weight=2.

On 1991 Jan 29 at UT17:34-17:52 A.C. Cook (Frimley, UK, 20cm reflector + image intensified CCD camera, transparency moderate to very poor) observed that Aristarchus was fainter than a nearby magnitude 7.3 star (SAO 146315) and may have varied in brightness and size. However the image intensifier output was quite grainy. No obvious signs of impact flashes or cosmic rays seen during a visual inspection of the video tape recorded. Foley commented that from UT 18:53-19:10 the Earthshine was strong with the naked eye and Aristarchus was bright as expected. The Cameron 2006 catalog ID=418 and weight=0. The ALPO/BAA weight=1.
On 1991 Jan 29 at UT17:56-18:01 A.C. Cook (Frimley, UK, 20cm reflector + image intensified CCD camera, transparency moderate to very poor) observed that Aristarchus was fainter than a nearby magnitude 7.3 star (SAO 146315) and may have varied in brightness and size.

On 1991 Jan 29 at UT17:34-17:52 A.C. Cook (Frimley, UK, 20cm reflector + image intensified CCD camera, transparency moderate to very poor) observed that a bright spot near Griomaldi appeared to vary in brightness - however a possible explanation was found because the image intensifier was found to vary in sensitivity across its imaging surface. The Cameron 2006 catalog ID=418 and weight=0. The ALPO/BAA weight=1.

On 1788 Dec 02 at UT 04:35 Schroter (Lillienthal, Germany) noted that Aristarchus was extraordinarily bright, like a star. The Cameron 1978 catalog ID=51 and the weight=4. The ALPO/BAA weight=3.
On 1983 Jun 14 at UT22:10-23:15 R. Mosely (Coventry, UK, 3" refractor, x38, seeing IV-V) observed a limb brightening near Olbers, though the cdrater itself was not visible in Earthshine. By 22:30 the glow seemed to spread a little vurther to the north. The ALPO/BAA weight=1.
On 1983 Jun 14 at UT22:10-23:15 R. Mosely (Coventry, UK, 3" refractor, x38, seeing IV-V) observed a limb brightening from the vicinity of Pythagoras to the north pole cusp. The ALPO/BAA weight=1.
Observer saw a pinpoint of white light almost as bright as Aristarchus. This has been assigned an ALPO/BAA weight of 2.
Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer from Thessoloniki, Greece, observing site near Bafra Serrain, Greece, 4"refractor, seeing excellent) "Observer took a series of expousres on a portable scope of the Moon. On one of them a very bright slightly elliptical spot was seen. Spot was very close to the Proclus C crater. Upon analysis it was claimed that the spot of light had rotated the direction of illumination of shadows in adjacent craters - however subsequent analysis casts doubt on this. Papers on this report were published in Icarus. Rast and Maley suggested that it was sun glint off a spinning US ex-military weather satellite that just by chance came across the field of view of the Moon a few tens of seconds around the time of the photographed flash. Was this a coincidence or not? If it were a satellite sun-glint then the satellite would have to be tumbling incredibly fast in order for the flash to be so sharp in the photograph - so the satellite explanation is not completely 100% confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The ALPO/BAA weight=2.
In 1949 May 02 at UT 03:30-04:00 Barcroft (Madera, CA, USA, 10" reflector, x96) observed in Aristarchus crater, in Earthshine, a dull glow -- silvery phosphorescence.This was not visible for 30 min prior. Cameron comments that this is a confirmation of Wilkins TLP from a few hours earlier? The Cameron 1978 catalog ID=519 and weight=5. The ALPO/BAA weight=2.
On 1822 Jan 27 at UT 20:00? F. Struve (Pulkovo Observatory? Russia) observed near Aristarchus an 8th magnitude star-like point. Seen through overcast! (Klado gave date as 1821 but must be in error according to cameron). The Cameron 1978 catalog ID=95 and the weight=4. The ALPO/BAA weight=2.
A lunar aurora on the dark limb was seen by Heywood and others of Westville, Ohio, USA, using a 2" refractor at x60. Observer saw misty like light in dark part, not like earthshine - seen repeatedly by him and others in Nov., Dec, and Mar 29, 30 1884. Displays on Moon similar similar effects on Earth/Aurora? Cameron 1978 catalog ID=239 and weight=4. ALPO/BAA weight=3.
------------ On 1971 Jul 27 at UT 18:30 Miranda (Piaui, Brazil, 4" refractor, Moon at 70deg altitude) observed Beaumont to have a curious brilliance in its interior: suspected a change (Apollo 15 watch?). The Cameron 1978 catalog ID=1301 and weight=2. The ALPO/BAA weight=2.
