     reflector, seeing IV-V, some spurious colour prsent) observed that the 
     central peak of Alphonsus was brighter in red light than in blue, so 
     much so that at the start of the session the peak could hardly be seen 
     in blue light. The central peak varied in brightness in red light but 
     not in white light. The central peak of arzachel was brighter than that 
     of Alphonsus in white light but had no colour - Arzachel's central peak 
     did however appear to fade in brightness over time (or was it Alphonsus 
     getting brighter?). Cameron 2006 catalog ID=177 and weight=3. The

     On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer, (Hoydalsvik 
     (Hakonsgate, in West Norway, 60mm refractor) photographed the Moon 
     using High Speed Ektacrome (400ASA) film with good focus. The TLP was 
     located on the southern slope of Sasserides H and was pink in colour 
     with some buish in it. The coloured area was circular with a diameter 
     of 0.5 minutes of arc. Only one exposure was taken. The photograph was

     USA, 15cm reflector at x340, seeing Good) saw a strange blue 
     light above the surface of the Moon where the night and the 
     day meet. He observed this light for more than 30 min and it 
     did not appear to move. It appeared like a star in that the 
     rays of light came from it. The observer adds that he first 
     thought thst the objects was a star, but later decided that it 
     had to be on the Moon itself. A drawing shows the blue spot 
     near the rugged south west (IAU?) limb of the Moon. The editor 
     of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954, 
     p146) was unable to identify the craters drawn. The editor 
     speculates that the observer saw a high mountain peak with its 
     summit in sunlight and detached from the illuminated regions - 
     however this would not explain the blue colour. Note this is 
     an ALPO observation and does not apear in the Cameron

     A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and 
     definition fairly good. Observer noticed that the Mare seemed covered 
     with a close network of innumerable streaks, and spotted with countless 
     numbers of light specks, so that it would hardly be possible to 
     delineate them all in one night. The spots and streaks together must 
     have numbered ~1000. The observer had never seen anything like the 
     number of spots and streaks. Peirce A, was not at all easy to se and 
     neighboring spots almost as bright made it difficult to distinguish

     quite good) noticed a faint red glow at the south west wall of Gassendi 
     covering a span of about 35 deg arc. The observer had some doubts about

     observed the following in Aristarchus during a lunar eclipse: "It 
     appeared much fainter than ever before seen in ecl. by Moore. Fainter

     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

2019-Dec-18 UT 06:57-07:34 Ill=61% Aristarchus observed by Hall on 1965-11-15

     Aristarchus 1965 Nov 15 UTC 05:55-10:00 Observed by Hall, Johnson, 
     Nordling (Pt. Tobacco, MD, USA, 16" reflector x400), Genatt (Greenbelt, 
     MD, USA, 6" refractor, x50 & 20" reflector x400), Wagmann (Pittsburgh, 
     PA, 30" refractor). "Color on c.p. detected with Trident MB, not seen 
     vis. at Port Tobacco. Network alerted & 6 responded. 4 did not see 
     anything unusual; 2 others did & saw red on c.p. in 6-in refr.. but not 
     in 20-in refl. at 400x; other saw indistinctness. Port Tobacco obs. 
     took 5 rolls of film in blue & red & neutral. Phenom. not detectable on 
     them, but focus was poor. Blue image had most detail, whereas would 
     expect red or neutral to. Phenom. still present at dawn in Moon Blink 
     device." NASA catalog weight=5. NASA catalog ID #914.

2019-Dec-22 UT 06:11-07:08 Ill=18% Aristarchus observed by Gruithuisen_F on 1821-7-25 *

     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.

     Macrobius 1938 Jun 02 UTC 18:00? Observed by McLeod (England? 5" ? 
     reflector) "Changes in dark areas. (near Proclus where Green saw 
     phenomenom. see #443)" NASA catalog weight=2 (low). NASA catalog ID #

2019-Dec-31 UT 00:05-00:42 Ill=21% Brenner_F observed by Collins_M on 2012-5-25

     On 2012 May 25 UT 05:35 Brenner F crater was recorded in a larger 
     area image by M. Collins (Palmerstone North, New Zealand, ETX-90 
     with LPI imager (monochrome mode) - seeing not good). He took a 
     sequence of 108 images from 05:35-05:40UT, and in the 65th frame, 
     a light spot, approximately 4 pixels wide can be seen just 
     outside the western illuminated rim of Brenner F. It is not 
     visible in any other frames. The exposure time was 0.125 Sec. 
     Because the western edge of the spot is very sharp, and the rest 
     of the Moon is slightly blurred due to seeing, it is thought that 
     this was most likely a cosmic ray event in the CCD camera - the 4 
     pixel width was perhaps contributed to by the image compression.
     It could also be some bright surface spot that was made invisible 
     most of the time by poor seeing, and then during a brief period
     the atmosphere is sharp enough at that locality to make it 
     visible. ALPO/BAA weight=1.

2019-Dec-31 UT 00:41-00:42 Ill=22% S_Pole observed by Masini_R on 2009-1-30

     On 2009 Jan 30 ay 22:35:20UT +/-2 min R. Masini (Perth, Australia) saw 
     a bright clound just west the south pole and along of the southern 
     limb. The effect lasted a few seconds and faded. It was seen with the 
     naked eye. There was a grazing occultation of a 6th magnitude star from 
     this site, however the star would have been in the wrong place at the 
     time of the TLP. The ALPO/BAA weight=2.
