     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.

2012-May-02 UT 21:47-22:01 Ill=85% Bullialdus observed by Cook_AC on 1980-12-18

     On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector, 
     40-250x, S=IV and transparency good) found the north west wall to be 
     brighter in red than in blue light, however the effect faded during 
     21:29-21:41UT and was gone by 22:40UT. There was however spurious 
     colour on the north west wall. M. Cook (Frimley, UK) found the central 
     peak to be both bright and diffuse, and brighter in red than in blue 
     light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright & 
     previous area decreased in size. No detail in white or red, just 
     visible in blue. Sketch (J. Cook) Orange out on NW rim & on NW side of

2012-May-02 UT 21:47-21:48 Ill=85% Aristarchus observed by Manske_R on 1989-7-15

     Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier, 
     Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl 
     Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske 
     initially observed a reddish tinge on the SE rim of Aristarchus. The 
     colour was present in different eyepieces. Two other pinkish tinge 
     areas were seen on the SE and NE rims. 4 of the observers did not see 
     colour. Independent confirmation was made by Don Spain (KY) and Smith 
     in LA. Full details can be found on the following web site:

2012-May-02 UT 21:47-22:38 Ill=85% Plato observed by North_G on 1992-5-13

     On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in 
     Plato mostly concerning the visibility of floor craterlets, however 
     observer seeing varied from III-V. North (UK, 18.25" reflector) 
     reported "Colouration and floor craterlets very prominent. Seeing 
     Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector 
     seeing=III-IV) found the floor to be bright and in the better moment of 
     seeing detected floor craterlets. The WNW spot was misty some of the 
     time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing 
     conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector, 
     seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog 
     ID=445 and the weight=5. The ALPO/BAA weight=2.


2012-May-02 UT 21:52-23:10 Ill=85% Aristarchus observed by Migon on 1969-7-26 *

     Aristarchus 1969 Jul 26 UT 02:30-03:00 Observed by Migon (19" 
     refractor), Nosgueira (10" refractor), Cardoso (13" refractor) all from 
     Rio de Janeiro, Brazil "Crater was gray-bluish, different from any 
     other region & unusually bright. Cardoso saw brightening, used blue, 
     red, green & neutral filters. Apollo 11 watch, daSilva says obs. no 
     good, obs. was in-experienced. However it is similar to many other obs. 
     with much experience)." NASA catalog weight=2 (low). NASA catalog ID 
     No. 1187.


2012-May-02 UT 21:54-23:34 Ill=85% Plato observed by Foley_PW on 1983-7-21

     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.


2012-May-02 UT 22:01-23:35 Ill=85% Aristarchus observed by Trouvelot on 1880-1-23

     Aristarchus 1880 Jan 23 UTC 20:00? Observed by Trouvelot (Meudon,

     On 1992 May 13 at UT 22:30 R. Turner (Wolverhampton, UK, 3.6" 
     reftactor, x50) noticed that there was a white spot on the WSW rim that 
     he had not seen earlier. The Cameron 2006 catalog ID=445 and weight=5.
     ALPO/BAA weight=1.


2012-May-05 UT 23:36-01:19 Ill=100% Lunar_Eclipse observed by Besanceas on 1901-11-25 *

     On 1901? Nov 25/25 at 23:00UT Besanceas (France?) observed: "During 
     lun. ecl. (mid-ecl. at 0118 on 26th) a bright area seen on moon. 
     Another(?) obser. saw an obj. like a fiery comet leave the moon! (Date 
     given by Midllehurst was 1900 but must be wrong-not FM then. FM in 1900 
     but no ecl. Partial ecl. on 10/27/01 at 0315. Ref. by M is wrong =

     Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan, 
     36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA 
     catalog weight=5 (very high). NASA catalog ID #1268.


2012-May-27 UT 23:39-01:01 Ill=41% Messier observed by Robinson_JH on 1982-12-22 *

     On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK, 
     10" reflector, x150, seeing=IV-V) could not distinguish between Messier 
     and Messier A. The tail of these features was very bright - two 
     telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III) 
     could see Messier A but found Messier itself obscured - just see the 
     west wall and thought that the comet like tail was unusual as it did 
     not appear divided. The Cameron 2006 catalog ID=192 and weight=5. The 
     ALPO/BAA weight=3.


2012-May-30 UT 23:10-23:24 Ill=73% Archimedes observed by Miranda on 1971-8-1 *

     On 1971 Aug 01 at Ut 19:00 Miranda (Plaui, Brazil, 4" refractor, x80) 
     observed two grooves going from east to west, broadening toewards the 
     west, across Archimedes. A drawing was supplied. Apparently this was 
     the first time that this was ever seen. Cameron suggests rays? and also 
     says that in fact a similar phenomenon reported before in neasrly the 
     same position (Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and 
     weight=2. The ALPO/BAA weight=1.
