     Herodotus 2022 Sep 27 UT 23:25-23:50 A. Anunziato (Parna, 
     Argentina - 105mm Meade EX 105, x154) near the shadow of the E 
     wall a slightly bright dot was seen, with a slight shadow. 
     Observer notes that this maybe as a result of observational 
     bias as they were looking for a couple of white dots on the 
     floor following a BAA/ALPO lunar schedule request and also the
     feature seen (if real?) was at the resolution linits of their 
     telescope. They also saw craterlet Herodotus N shining quite 
     brightly on the NW rim, but this is normal.We shall therefore 
     assign an ALPO/BAA weight of 1.

2024-May-16 UT 20:57-22:47 Ill=63% Plato observed by Foley_PW on 1975-4-19

     On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in 
     Plato on east. Fiton at UT20:45 found blue along the south wall 
     at the east (IAU?) end, which was very bright white. Blueness 
     extended towards the large landslip at the east of the formation. 
     Immediately north of the landslip, where the bright wall curves 
     first westwards, then again northwards, red could be faintly 
     detected, folloowed by a very faint blue. All other parts of the 
     formation were normal. Examination with a Moon blink device 
     revealed no colour blink. J-H Robinson also found blue, with red 
     on the west wall (exterior?). By 21:30UT Fitton found Plato to be 
     normal and so was Proclus, though he did find Epigenes (bright 
     cresecent of east wall only) slightly blue to the N.W and red 
     to the S.E. Mare Crisium was normal. Prominent spurious colour 
     seen on Venus, but it was low in the sky, with blue to the north 
     and red to the south. However J.H. Reading, managed to see the 
     north east floor blurred and slightly blue from 22:45-23:00UT. 
     These reports are BAA observation. The ALPO/BAA weight=2.

2024-May-18 UT 20:20-22:05 Ill=80% Plato observed by Foley_PW on 1983-7-20

     On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector, 
     seeing II-III) noted that the south wall of Plato at the 11 o'clock 
     position, at the location of a cleft, was fuzzy on either side of the 
     cleft. There was also a deep red colour along the cleft and the outside 
     wall. The colour had gone by 22:40 though. All other parts of the rim 
     of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III) 
     sketched some obscurations at 22:03UT. At 22:08UT the red colour 
     reduced to a red line and vanished by 22:37. The south wall obscuration 
     varied in size and there was a possible obscuration at the 7 o'clock 
     position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and 
     M.Cook's observations. Detail inside the crater was sharp, but colour 
     oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km 
     away had atmospheric ripples affecting his observations. At 21:36UT G. 
     North described the south wall as odd in appearance and the terrain 
     south of this was lacking in detail - this was odd because elsewhere 
     Plato was nice and sharp. At 21:45UT though the north section of the 
     crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5. 
     The ALPO/BAA weight=3.


2024-May-18 UT 21:35-22:34 Ill=80% Campanus observed by Bush_S on 2014-1-11

     Campanus 2014 Jan 11 UT 22:00-22:30 S.Bush (UK, 6" SCT, x180, 
     seeing average) made a sketch of the Campanus and Mercator 
     craters. He found that the central peak of Campanus difficult 
     to resolve and the floors of both craters were devoid of 
     detail. Mercator was the lighter shade of the two floors. 
     Earlier at 19:47 UT M.Brown (Huntingdon, UK) imaged this 
     region and using Registax resolved details on the floors of 
     both craters, though Mercator clearly was slightly lighter in 
     floor shade and had less detail on its floor than Campanus. 
     The most likely explanation was that it was just seeing 
     effects blocking the visibility of detail - this of course is 
     less of a problem for a Registax usid on the CCD image. 
     However just to be sure this observation is being given an 
     ALPO/BAA TLP weight of 1, to encourage visual observers to 
     attempt this observation under similar illumination and 
     seeing.


2024-May-18 UT 21:45-22:34 Ill=80% Mons_Piton observed by Louderback_D on 1983-8-19

     On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA, 
     3" refractor, x150) found that the direct sunlit side of Mons Piton 
     mountain (E) was brighter than (his designated) points C and D and this 
     happened at the same time as some "blurring"at 07:15UT. The darker 
     side, between C, A and B were not so dark through a red filter as 
     through a blue filter (this was the opposite of what had been seen 
     before at a high sun angle). Louderback suspects that there had been a 
     colour change since he last observed. He also noted that in red light 
     the whole lunar disk appeared fuzzy and out of focus. Louderback noted 
     a 1 sec brightness on the east slope and the whole mountain sharp in 
     blue light. The Moon's altitude was low though. Brightness measurements 
     were 4 in blue light and >= 4.6 in red light and "so illdefined almost 
     blended into plain". Cameon commnets that a telescope colour/focussing 
     issue may have been at work here! The Cameron 2006 catalog ID=226 and 
     weight=4. The ALPO/BAA weight=1.

     visible in white, red or blue filters. This was not a telescopic 
     effect. "Obs. 4.5h. Says it & next 5 nites obs. were due to high 
     pressure system W. of obs.". Foley found nothing unsual in Aristarchus 
     in his observing session, which overlapped Fittons. The 1978 catalog 
     ID=1396 and weight=3. The ALPO/BAA weight=1.


2024-May-19 UT 21:21-21:54 Ill=87% Prinz observed by Foley_PW on 1975-2-22

     On 1975 Feb 22 at 20:04-22:50 P.W. Foley (Kent, UK, 12" reflector, 
     seeing=good) observed Prinz to have a diffuse white obsecuration. There 
     were pulsations of 30-50sec intervals. Effect ceased at 22:50UT and 
     indeed was fading earlier from 22:35UT. Photgraphs were taken but 
     showed nothing unusual and no colour. Aristarchus was also negative.
     The Cameron 1978 catalog ID=1396 and weight=3. The ALPO/BAA weight=2.


2024-May-19 UT 21:28-21:54 Ill=87% Aristarchus observed by no on 1969-5-28

     On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5" 
     reflector, x300) suspected a short duration flare up on the W 
     wall of Aristarchus at 0.682 and 0.397, but it may have been due 
     to poor seeing. No events seen at Kepler (Apollo 10 watch). The 
     Cameron 1978 catalog ID=1149 and weight=4. ALPO/BAA weight=1.


2024-May-19 UT 21:35-21:54 Ill=87% 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 
     c.p. Similar effects seen on  other craters. (madej) c.p. & W. rim wall 
     very sharp. c.p. disappears in yellow but still seen in purple. 
     (pedler) c.p. > red than blue but no obstruction. W wall interior 
     dusky, darker in blue." A.C. Cook's photo depicts the central peak as 
     very bright. Cameron 2006 catalog TLP ID=120 and weight=5. ALPO/BAA 
     weight=2.


2024-May-19 UT 21:42-21:54 Ill=87% 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.


2024-May-20 UT 19:52-20:18 Ill=93% Aristarchus observed by MacKenzie on 1970-4-18 *

     Aristarchus-Herodotus 1970 Apr 18 UT 20:14 Observed by MacKenzie 
     (UK,2.5" refractor x45, seeing Antoniadi I) "Fairly strong blink 
     in a spot 1/2 way between the 2 craters. Drawing (Apollo 13 
     watch). NASA catalog weight=2. NASA catalog ID #1257. ALPO/BAA 
     weight=2.


2024-May-20 UT 19:52-19:58 Ill=93% Langrenus observed by Moore_P on 1992-2-16 *

     On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5" 
     reflector, seeing=III) found the north rim area to be both very 
     bright and misty - though he did not think it to be a TLP but 
     wanted it to be recorded, just in case. The Cameron 2006 catalog 
     ID=440 and the weight=1. The ALPO/BAA weight=2.


2024-May-30 UT 01:47-02:19 Ill=57% Triesnecker observed by Allen_DA on 1966-7-10 *

     Triesnecker 1966 Jul 10 UTC 02:00-02:15 Observed by Allen (Cambridge, 
     England) and other observations by Corralitos Observatory (Organ Pass, 
     NM, USA). Described in NASA catalog as: "Faint illum. of a ridge in 
     shadow; faded quickly (in BAA judged dubious). Not confirmed by 
     Corralitos MB." 12?" refractor (x280) used at Cambridge and at 
     Corralitos 24" reflector. NASA catalog weight=1 (very low). NASA 
     catalog TLP ID No. #956.
