2018-Sep-02 UT 00:57-03:33 Ill=62% Aristarchus observed by Bartlett on 1964-7-31 *

     Aristarchus 1964 Jul 31 UT 02:00-02:23 Observed by Bartlett 
     (Baltimore, MD, USA, 5" reflector x180) "Deep ravine on E.glacis 
     interrupted midway of its length by apparent break just below 
     rim of craterlet assoc. with EWBS. Normally, ravine is seen 
     continuous. Probable obscuration at pt, of break." S=7, T=5. 
     NASA catalog weight=4. NASA catalog ID #834. ALPO/BAA weight=2.


2018-Sep-02 UT 01:17-03:10 Ill=62% Vallis_Schroteri observed by Unknown_Observer on 1994-4-3

     On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a 
     darkening in the Cobra Head, Schroter's valley area of Aristarchus - 
     the best example that he had ever seen. The Cameron 2006 catalog ID=474 
     and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section 
     circular 1995 Oct, p125 and personal communication from David Darling 
     to the BAA on 6/6/1995. Note it is uncertain whether this refers to the 
     Clementine mission or to somebody who observed during the Clementine 
     mission, or somebody with that surname. Anyway if it is the Clementine 
     mission then the date is wrong - possibly the year should have been 
     1994? The Cameron catalogue does actually mention a TIFF on Clementine 
     mission? The Cameron 2006 catalog ID=474 and the weight=3. I am 
     assuming that the year should be 1994 and not 1995? The ALPO/BAA 
     catalog weight=1 until we can find out what the correct date is?


2018-Sep-02 UT 20:57-22:57 Ill=52% Gassendi observed by Foley_PW on 1977-11-3 *

     On 1977 Nov 03 at 22:13UT P.W. Foley (Kent, UK, 11" reflector, x285)saw 
     some flickering in Gassendi (Clouds on limb - according to Csmeron?). 
     The Cameron 1978 catalog ID=18 and weight=1. The ALPO/BAA weight=1.


2018-Sep-02 UT 22:53-00:16 Ill=52% Rupes_Recta observed by daSilva on 1971-6-16

     On 1971 Jun 16 at UT 07:08-07:09 Raimundo Nonato da Silva 
     (Parnaiba, PI, Brazil, 9.5" reflector, x90, seeing=good) 
     observed during a lunar eclipse that the Straight Wall 
     surroundings were darker than an observation from two days 
     earlier. At 07:09UT tonality became clearer. As dawn was in 
     progress and atmospheric turbulence, not sure if it was a TLP? 
     Other features were normal. The Cameron 1978 catalog ID=1297 and 
     weight=1. The ALPO/BAA weight=1.


2018-Sep-03 UT 02:00-03:22 Ill=50% Tycho observed by Sandel_J on 1996-2-12

     On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA) 
     noted a contrast effect inside Tycho at sunset. At 07:30UT there 
     was a slight, but definite illumination of small areas of the 
     crater floor west of the central; peak. Also seen by T. Ferrel 
     (Lawrenceville, GA, USA, SCT C8). This was oval in shape and 
     gray in colour - Ferrel noted some diffuseness. It brightened 
     over 30 minutes. At 08:11UT a definite brightness fade noted in 
     Tycho's central peak. The crater floor had increased 
     illumination of entire crater floor. ALPO/BAA weight=3. 


2018-Sep-03 UT 02:50-03:35 Ill=50% Plato observed by Wilkins_HP on 1944-8-12

     On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52" 
     reflector) observed that central craterlet in Plato was 
     unusually bright and shows up as a bright white spot on his 
     sketch - though this might have been artistic license in his 
     sketch. His written notes refer to the unusual lack of a rim 
     (especially the northern part) to this craterlet. 
     The ALPO/BAA weight=2.

2018-Sep-07 UT 02:41-03:34 Ill=10% Dawes observed by Hewick_G on 1997-10-28

     On 1987 Oct 28 at UT 05:05 G. Hewick (UK) observed a 1 sec duration 
     flash on the lunar surface (night side) whilst waiting to observe a 
     lunar occultation of X17959. The colour was yellow and the brightness 
     was approximately magnitude 1 - there was no movement. The location of 
     the flare was between Daws and Vitruvius (17N, 29E).


2018-Sep-07 UT 02:52-03:43 Ill=9% E_Limb observed by Unknown_Observer on 1883-3-6

     During an occultation of lambda Geminorum on the eastern limb
     the light from the star took 3 seconds to fade. Cameron 2006 catalog
     extension ID=8 and weight=2. ALPO/BAA weight=1.


2018-Sep-07 UT 02:56-03:43 Ill=9% Plato observed by Short_J on 1751-4-22

     James Short, Dr Harris and Mr Stephens saw initially a streak of 
     light on the shadowed floor of Plato. They were not expecting to see
     any light to reach the floor. Shortly afterwards they saw a second
     streak of light parallel to the first and this shortly divided
     into two. Gaps in the mountains were found for both streaks,
     but they were unable to understand why one of the streaks divided
     into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight
     of 5. The ALPO/BAA catalog assigns a weight of 1.

     showing a remarkable golden (yellow-golden) hue. This was a 
     repeat illumination observation for a W.E. Fox TLp observation 
     from 1938 Feb 14. The observer was wondering whether they were 
     in some way biased after reading the original report desription

2018-Sep-25 UT 21:25-23:08 Ill=99% Taruntius observed by Wildey on 1962-9-15

     In 1962 Sep 16 at UT08:05 Wildey, Pohn (Mt Wilson, CA, USA, 60" 
     reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in 
     magnitude in 2.5 hours - a photometric measurement. The average 
     magnitude for this age is 4.03, so therefore the crater had brightened 
     by two times above normal. The Cameron 1978 catalogID=769 and the 
     weight=5. The ALPO/BAA weight=3.

     In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5" 
     reflector) saw no dark bands on the inside of Aristarchus, 
     despite detail being seen elsewhere. He would normally have 
     expected to have seen bands at this colongitude, based upon past 
     observations. The ALPO/BAA weight=2.


2018-Sep-26 UT 23:04-00:59 Ill=96% Aristarchus observed by Brook_C on 2002-9-23

     On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that 
     the bands inside Aristarchus varied (UT22:45-22:56) in definition 
     whilst the rim of Herodotus and the rays of Kepler and Copernicus 
     remained sharp. These bouts of variation were 1-2min in duration. At 
     23:56UT when he checked again the periodic blurrings of the bands were 
     still present. The observer suspected atmospheric effects. M.Cook 
     (Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the 
     west wall - but this may have been because of poor transparancy. The 
     ALPO/BAA weight=1.


2018-Sep-26 UT 23:05-00:51 Ill=96% Aristarchus observed by Foley_PW on 1983-10-23

     Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK, 
     12" reflector, seeing=II) noiced at 19:00UT an extended bright 
     spot on E wall and extending beyond. This was brighter than other 
     areas of the crater. There was also occasional star-like 
     glistening. Foley comments that the inside of Aristarchus was 
     slightly obscured. The TLP started fading from UT20:30 and 
     finished by 01:30UT. six out of nine independent observers 
     confirmed the effects seen. In total 14 observers observed, 9 
     reported back and 6 found abnormalities in Aristarcus though all 
     encountered variable seeing conditions - some had spurious 
     colour. Cameron comments that this was one of the best 
     recorded/confirmed TLP events. All CED brightness measurements 
     obtained were very high. Moore, Nicolson and Clarke (5" refractor 
     and 15" reflector, 230-350xseeing III) found the crater to be 
     very bright at 19:11UT through a 5" refractor and there was a 
     blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also 
     saw a very bright star-like area on the eastern wall but this was 
     not defined as it usually is. The crater was also very bright at 
     22:43UT using the 15" reflector available to these observers. At 
     01:07UT they used a Moon blink and discovered that the bright 
     region was bright in blue light and less bright in red - although 
     this was not a detactable blink when switching rapidly between 
     filters. They found that the crater had returned to normal by 
     01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large 
     diffuse spot on the east of the crater that was brighter in blue 
     than in red light and the CED device gave a high reading. J.D. 
     Cook (Frimley, UK, seeing III-IV) made a skecth that showed the 
     bright spot extended on the east wall - again the CED reading was 
     high and a lot of detail was visible on the floor. A.C. Cook 
     (Frimley, UK, seeing III-IV) also noted remarkable detail and the 
     bright (as confirmed by CED) blob on the eastern rim. G. North 
     (Sussex, UK, seeing III-II) also confirmed the bright blob on the 
     eastern wall. Wooller found the north west wall was a dirty 
     yellow colour - though no colour was seen elsewhere in or outside 
     the crater. Mosely found the crater to be bright and his sketch 
     revealed the extension of the bright blob on the eastern rim and 
     again a great deal of interior detail. Amery (Reading, UK, seeing 
     III) found Aristarchus to be "a brilliant splash against dulled 
     background in violet filter, especially polarizing filter. CED + 
     polarizer readings high, but not as high as previous night". 
     Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious 
     colour a total mess around Aristarchus & nothing abnormal seen". 
     A photograph was taken at 20:50UT reveals the  bright blob and 
     entire detail. Peters (Kent, UK, seeingIII-II) observed  
     Aristarchus with a UV screen from 20:15-21:23UT and comented that 
     althogh being very bright, there was no variation between white 
     and UV. It was checked with a Moon Blink device and the radial 
     bands were  clearly seen in white light, < in blue. The Cameron 
     2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.

     Proclus. Using a 15.2 cm refractor he conducted a Moon blink search 
     with Wratten 25a and 38a blue filters. His report goes as follows: 
     Moon Blink carried out. In Red 25 Proclus looked nearly the 
     same as in white light. Through the Blue 38a filter, however, only the 
     brilliant lit south east wall was clearly visible. The northeast wall 
     was very dim with this filter. With no filters the NE and SE wall were 
     brilliantly lit, the SE wall was almost as bright as Aristarchus. A 
     thread like strip along the NW wall, possibly the rim of the crater, 
     was also brilliantly illuminated. The interior of the crater was a 
     featureless stygian black with the exception of a brilliant (intensity 
     9) thread of light that ran parallel  to the illuminated east wall.
