Mare Crisium 1826 Apr 12 UT 20:00 Observed by Emmett (England?) "Black moving haze or cloud". NASA catalog weight=2 (low). NASA catalog ID 109. ALPO/BAA weight=1.
On 1966 Sep 20 at UT 03:22 Three Astronet observers (Phoenix, AZ, and Los Angeles, CA, USA) (independently?) reported flashes in Grimaldi crater. One observer was in Phoenix AZ, and another in Losa Angeles, CA, so probably not due to the atmosphere. Cameron comments that the astronaut Schmidt on Apollo 17 saw a flash in it while orbiting the Moon. the Cameron 1978 catalog ID=977 and the weight=5. The ALPO/BAA weight=4.
On 1969 Jul 19 at UT 19:30-21:30 Gervais (Lodure, France, 4.5" refractor?) saw the whole region of Aristarchus and its environs as brighter than normal. Two photographs were obtained. The Cameron 1978 catalog ID=1156 and weight=5. At UT 20:30-20:55 Oliver (Spain, using a reflector) found the Aristarchus to have brightened by about 1 magnitude. From UT 20:12-20:30 the crater had been normal. The Cameron 1978 catalog ID=1167 and the weight=2. At UT 21:00-00:35 P. Mourilhe Silva (Rio de Janeiro, Brazil, 19.5" refractor) saw Aristarchus as a very bright elliptical shape which extended to the north like a bridge between two points. Jose M. L. da Silva and Ronaldo Mourao (Rio de Janeiro, Brazil, 13" refractor) saw a brightening on the north west wall from 21:24-23:22UT intermittently but cont'd. Wall was extraordinarilly bright, along NW wall brighter. Moseley (Armagh, Northern Ireland, UK, 10" refractor) detected an unusual bright, along north west wall, brighter than normal in Earthshine and brighter than crater. It was not constant, but pulsated irregularly with frequency of 20 seconds and amplitude 0.75-1.0 magnitudes. No colour seen or obscuration though lokked for. Clouds interrupted observations. Vasquez (Valparaiso, Chile, 12" reflector) saw it as a very luminous point of magnitude 1. Wairy Cardoso (Rio de Janeiro, Brazil, 12" reflector and 18" refractor) noted a bright. 1s??? The Cameron catalog ID=1168 and the weight=5. The ALPO/BAA weight=4.
Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm refractor) saw a bright bluish spot near Grimaldi. 20:43 a flash was seen by Thinon. Delaye saw flashes at 20:44 and 20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W (IAU??) of Grimaldi. However there is a bright spot near Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA weight=2.
Theophilus 1969 Jul 19 UT 19:30-21:30 Observed by Fox (Notts. England, 6.5" reflector) and Ringsdore (England, 15" reflector). Fox saw intermittent glow in Theoph. for > 2h (time not given). Ringsdore confirmed. (Apollo 11 watch)" Confirmed by Baum 21:00-21:20UT. NASA catalog weight=5. NASA catalog ID No. 1166. ALPO/BAA weight=4.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red glow in Earthshine in Gassendi as shown in a sketch. Apparently Gassendi can often show up red colours (according to Cameron) but rarely is this seen in Earthshine. Foley saw the sketch and suspects that the location was Gassendi. The Cameron 1978 catalog ID=397 and weight=2. The ALPO/BAA weight=3.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces). Inspections during the above time period revealed no changes in brightness. Previous observations of this area had never shown such an unusual brightness, and Arthur likened the brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The observer was an experienced observer. ALPO/BAA weight=2.
Alphonsus area? 1949 Jun 01 UT 22:06 H.P. Wilkins (Kent, UK, 6" reflector x200) observed a bright white 1 sec stationary (mag 3?) flash in Earthhsine, close to the central meridian, and due E of Theophilus (potentially in the general area of Alphonsus?). The flash was approximately 6 km in diameter. ALPO/BAA weight=1.
Klein (in Albategnius) 1971 Apr 31 UT 21:30 - 1971 May 01 UT 00:00 Observed by Fitton (England, 8" reflector, x200, filters) "Attention distracted from Ptolemaeus to Klein where floor was not normal. It had a pink line at foot of inner N. wall which was bright in sunlight. Pink extended from N. to W. pt. Floor in NW quad. was reddish-brown. All similarly illum. craters were examined & no trace. Klein shifted to all parts of lens but color persisted, but could not be induced in other craters. At 2230h floor took on more color in NW. In filters floor detail vis. in red, almost invis. in blue, c.p. barely vis. Color bright in red, & black in blue filter. In white light looked like atm. above surface. Ptol. was equal in red & blue, & also other craters. All seemed normal again on May 2nd. (date in ref. gives Apr 30, Moore gives Apr 31?

On 1969 Jul 20 at UT 19:55-20:10 Delaye, Thinon, Donas, and Jourdran (Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT Aristarchus to be bright and in it pulsations with 10 sec duration. At 20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and pulsations of variable duration. At 20:55:50UT just a feeble flash. Cameron comments that this is probably not atmpsheric effects as the period is too long - also it was during the Apollo 11 watch. The Cameron 1978 catalog ID=1175 and th weight=3. The ALPO/BAA weight=3.
Atlas 1969 May 22 UT 21:20-21:40 Observed by Germann, Wild, Vieli (Zurich, Switzerland, 6" reflector) "Rim towards the sun was bright. Part of time was interrupted. (Apollo 10 watch)" NASA catalog weight=3 (average). NASA catalog ID #1135.
On 1969 May 22 at UT23:20 an unknown observer reported some brightenings with pulsations in Aristarchus crater, Cameron suspects atmospheric aberrations. This was during the Apollo 10 watch. The Cameron 1978 catalog ID=1136 and weight=1. The ALPO/BAA weight=1.
2005 Jul 13 UT 01:18 W.Watson (USA, East coast, transparancy: heavy hazy cirrus, and the only other object visible was Jupiter) observed a naked eye flash on the Moon in the northern hemisphere, with a magnitude of -3 to -4. The ALPO/BAA weight=1.
On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo, Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish area on the north west(east?) wall of Eudoxus crater. An English Moon Blink device showed it dark in blue and opaque in red. Reddening remained unchanged while comparing it to adjacent region and Aristotles. Colour index was toward dirty orange. Colour most apparent in the good moments of seeing and disappeared in the poorer moments of seeing, Cameron says that this is opposite to what was expected if the effect was atmospheric in origin and no colour was seen in Aristotles. Apollo 11 watch. Cameron 1978 catalog ID=1177 and weight=3. The ALPO/BAA weight=3.
On 1971 May 01 at UT21:00-21:50 Staedke, Jorgensen (Berlin, Germany, x40 with filters) observed on Maurolycus a coloured, luminous projection from the crater into and through the small crater on the north rim.

On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11" reflector) photgrapphed a broad bright band stretching east and north of Cassini crater in 3 exposures taken 10 minutes apart. This photographic sequence shows a gradual widening towards Cassini and by the 3rd exposure the band is touching (and then obscuring) Cassini. A "fan" was visible in the north east and WSW directions, later this was seen as rays and this was even seen in the view finder of the camera. Cameron comments that this might be lens flare but suspects that it would not have been seen in the view finder. The Cameron 2006 catalog ID=427 and the weight=5. The ALPO/BAA weight=2.
Piton 1970 Apr 13 UT 22:06-01:30 Observed by Cutts (Waverton, UK) "Peak was bright (Apollo 13 watch. Shining in dark?)" NASA catalog weight=1. NASA catalog ID #1247. Similar illumination shown on Hatfield Plate 2E(left). ALPO/BAA weight=1.

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook (Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV) Orange discolouration seen on ESE crater floor. Moon blink tried, but no blink detected. By 21:10 the effect had lessened, but was still orange. By 21:50-21:58 the effect was smaller and perhaps more on the SE of the floor. Colour confirmed by Foley. Fitton may also have been observing. At 22:00 A.C. Cook observed and commented that a darkish, perhaps brown-orange colour seen - but suspected it was probably spurious colour - but by now the seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of several features, including Theophilus, had not noticed anything unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect a blink, but noticed intermittent darkining on the shaded area on the E. floor, but seeing was now IV. The darkening was more noticeable in blue than red light. BAA Lunar Section observation. 2006 Cameron catalog ID #40 weight=3. ALPO/BAA weight=1.
2 deg S of Maskelyne (29E, 1N) 1969 May 25 UT 01:15-01:56 Observed by Jean, Barry, Bernie, (2) Madison (Montreal, Canada, USA, 4" refractor) "Very vis. pink patch red as seen thru a yellow filter.

On 1990 Apr 04 at UT 21:30-21:50 B. LeFranc (France?) reported observing a white flame effect in Copernicus crater (sketch made) - though Foley comments that the actual location was east of the crater. The Cameron 2006 catalog ID=398 and the weight=2. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon examining drawing, and comparing with photos made under similar illumination was struck by the abnormality of a a small white blob in the north east corner of the shadowed floor. There should be no raised topography between the wall and the central peaks that could give rise to this. The making of the sketch overlapped with an earlier drawing made by Rony de Laet (Belgium) which did not show this blob. Subsequent attempts to find sketches/images at very similar illumination angles have failed to show the blob in the north east corner of the chadowed floor. ALPO/BAA weight=3.
Posidonius 1970 Apr 15 UT 21:05-22:10 Observed by Wanderley Nazareth (Sao Paulo, Brazil, reflector) "Intermittant pulsation. Drawing 20S interval for pulsations. (too long for atmospheric aberration? Apollo 13 watch)." NASA catalog weight=3. NASA catalog ID #1254. ALPO/BAA weight=3.

On 1982 Oct 26 at UT 20:41-22:22 P. Madej (Huddersfield, UK, seeing=II and transparency=good) found that a blurring effect on the crater Yerkes had spread to Picard (~3.5 deg brightness). The effect was not detected in yellow light from the Wratten 15 filter, but a brightness change was picked up in red Wratten 25 light. J.D. Cook found dark surrounding Picard bright illumination. The Cameron 2006 catalog ID=188 and weight=5. The ALPO/BAA weight=3.

On 1989 May 17 at UT Fabian (Chicago, IL, USA, 4" reflector, x35-x50 and 8" reflector) noted a pale blue colouration in the ridges situated west of Aristarchus and north of Herodotus craters, in the vicinity of the terminator (and on the night side). Aristarchus itself did not have any colour. Ďt was only area with such color though there were numerous others of similar elevation and relation to term. The colour was seen in a 4" Cassegrain telescope, but when an 8" reflector was used at 02:30UT, even with the same eyepieces. Cameron comments that maybe the larger telescope spread the colour out? The sketch that Fabian suplied, suggested to Cameron that the TLP was located at Herodotus, and the ridge was part of Schroter's valley - Cobra Head. The Cameron 2006 catalog ID=364 and the weight=2. The ALPO/BAA weight=2.
On 1891 Sep 16 at UT 19:00? Pickering, based at Arequipa, Peru, and using a 12" reflector, saw in Schroter's Valley and the vicinity "Dense clouds of vapor apparently rising from its bottom and pouring over its SW wall torrds Herodotus.

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5" reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side of Aristarchus and red haze on the west side. At 00:00UT details were more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At 00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the area was bright, but was black in a red filter. At 00:53UT the features were clear and the colour gone and the brightness had decreased to 9. Cameron comments that the colour was not due to temp. inversion because of being dark in the red filter, implying a medium). The Cameron 1978 catalog TLP ID is 1428 and the weight=1. This is an ALPO report. The ALPO/BAA weight=1.
