2026-Jul-02 UT 09:24-09:52 Ill=95% Aristarchus observed by Curtis on 1987-6-14

     Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and 
     Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial 
     Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian 
     and the 8" f10 SCT Celestron) "On the night 13/14  June  11:42 P.M. to 
     3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people 
     witnessed this event and all three of them observed with three 
     different telescopes to rule out instrumental aberration. These three 
     pople were members of the Madison Astronomical. The three observers 
     involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis 
     took detailed notes of the event as he observed it. The observations 
     were made at the Yanna Research Station, Carl A. Fosmark Jr.
     Memorial Observatory of the Madison Astronomical Society following the 
     annual picnic. This is MAS dark sky site and is located near Brooklyn, 
     Wisconsin. As they were observing the night sky they saw the Moon 
     rising and noted a strong orange color due to atmospheric effects. 
     Approximately 1/2 hour after the Moon rise they decided to turn one of 
     the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis 
     that as the Moon rose it began to loose the horizon color effect and 
     return to its normal color, but he found that the red color was not 
     leaving the crater Aristarchus. At first they all thought this was an 
     atmospheric effect but decided it was a real event since they detected  
     a second crater (Euler) showing red color on its rim. Keith Curtis
     said that the red color was very strong on the Western rim of 
     Aristarchus with a strong blue/green or aqua green on the Eastern rim. 
     Keith also reported that the glow opaque enough to prevent viewing of 
     the interior of crater Aristarchus. He said they observed until 3:00 
     A.M. daylight saving time or 8:00 UT. and the red glow was still 
     visible when they ended  their observing session. Robert Manske 
     description of the event was that he saw two craters glowing a strong 
     red and blue giving it a rainbow effect. He said that the red glow was 
     so strong he was unable to see the craters underneath during the entire 
     observing session. Concerning the orientation of the red and blue was 
     on the crater he stated that  he did not remember since he failed to 
     take any notes. Concerning whether there was any difference in 
     appearance when they observed it with the 17" f4.5 Dobsonian and the 
     8" f10 SCT Celestron. He said that he could not detect any difference 
     to the lunar formation or the color on it regardless of which telescope 
     he used. He did mention that as the Moon was rising it had the 
     appearance of one large Maria in the center of the disk. This illusion 
     disappeared as the Moon rose higher into the sky. When talking to Tom 
     Jacobs he said that he remembered that he did not see anything on the 
     Moon until 1/2 hour after Moon rise. He said that he remembered that 
     the entire Aristarchus region had a strong reddish or pinkish color. 
     All three witness all reported variations in the type of color they 
     were seeing. This would indicate that individuals color perception is a 
     major factor during a color event. Keith Curtis saw a very strong 
     coloration around the rim of the craters, where Robert Manske saw the 
     entire region covered by this red and blue coloration and he could not 
     see the interior of the craters underneath. Tom Jacobs reported that 
     the glow covered the entire crater but he could see the crater 
     underneath it. The Moon never achieved a height greater than 21 degrees 
     so it could be that what the observers saw was caused by the Earths 
     atmosphere. Further details can be found on the following web site:

2026-Jul-03 UT 07:19-07:59 Ill=90% Aristarchus observed by Madej_P on 1979-11-8

     On 1979 Nov 08 at 00:16UT P.Madej (Huddersfield, UK, 6" reflector, x48 
     and x110, seeing II and transparency very good) detected a small faint 
     orange spot, close to the centre, but not at the centre. Spurious 
     colour was visible on the northern flank of Aristarchus. The Cameron 
     2006 catalog ID=74 and weight=3. ALPO/BAA weight=2.

2026-Jul-03 UT 09:41-11:00 Ill=90% Theophilus observed by Mobberley_M on 1981-10-16

     On 1981 Oct 26 UT 20:44-21:14 M. Mobberley (Bury St Edmunds, UK, 
     14" Cassegrain, seeing III) noticed an ~100deg wide fan on the 
     floor of Theophius, radiating on the central peak upto the 
     surrounding base of the wall next to Cyrillus crater. This fan 
     had a hint of yellow/red. The observer did not consider this to 
     be abnormal - there was certainly no loss of focus here as far 
     as the observer was concerned, and no mention is made of this 
     effect in later observations that night. Plenty of spurious 
     colour was reported. The ALPO/BAA weight=2.

     refractor, x36-x140) found that the eastern half of Plato crater was 
     dark - and he checked this using several eyepieces. moderate 
     magnification resolved the dark region into bands, but too high a 
     magnification (x140) made the bands dissappear. The Cameron 2006

2026-Jul-06 UT 07:32-09:13 Ill=66% Plato observed by Mobberley_M on 1982-8-11

     On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a 
     photograph and made a sketch that revealed a needle-like shadow from 
     the west wall to near by the central craterlet - the latter was quite 
     clearly visible. What were not visible were the other four craterlets.

2026-Jul-06 UT 07:41-09:02 Ill=66% Tycho observed by Moseley_R on 1983-8-30

     Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6" 
     f/10 reflector, x60, transparency very good, seeing III, 
     improving with altitude) attention initially caught by the 
     impression of a rosy colouration along the NW crest and outer 
     wall. For perhaps 2-3 min this persisted - before fading 
     entirely. The observer felt that the cause may have been 
     psysiological - or short-lived spurious colour. However 
     interestingly nearby craters did not show the effect. A 
     sketch was made over a longer time span 00:15-00:40UT. 
     ALPO/BAA weight=1.


2026-Jul-06 UT 09:23-10:33 Ill=65% Lexell observed by Unknown_English_Observer on 1919-2-21

     In 1919 Feb 21 at UT 22:00? an unknown English observer observed in 
     Lexell crater an intensely dark line going out from it. The Cameron 
     1978 catalog ID=370 and weight=1. The ALPO/BAA weight=1.


2026-Jul-06 UT 09:26-11:02 Ill=65% Archimedes observed by Darling_D on 1981-9-20

     On 1981 Sep 20 at UT 08:00-09:40 D. Darling (Sun Praire, WI, USA, 
     12.5" reflector, x342, seeing=excellent) detected the small crater on 
     its western rim But not on the eastern floor. This was odd because both 
     are equal in size, furthermore smaller craters could be seen and the 
     Moon was at a high altitude above the horizon, so seeing not a problem. 
     Cameron 2006 catalog ID=154 and weight=3. ALPO/BAA weight=1. 


2026-Jul-06 UT 10:20-11:02 Ill=65% Aristarchus observed by Sage_VA on 1978-10-23

     Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK, 
     10.25" reflector, x250, Wratten 44a and 25, seeing II) noted 
     that Aristarchus was surrounded by a dark area in the blue 
     filter. They did not regard this as a TLP at the time. However 
     because Aristarchus is surrounded by blue material in real life, 
     this should have been brighter? For this reason, despite the 
     observer regarding this as a negative TLP, an ALPO/BAA weight=1 
     has been applied.

     Reiner 1986 Jun 04 UT 09:15-09:33 Observed by Darling (Sun Praire, WI, 
     USA, 12.5" Newtonian x79, x40, x35, Seeing 6, sky clear and steady - 
     Moon 9deg above horizon). David Darling was out on the morning of 4 
     June observing the planet Mars. While studying Mars the crescent Moon  
     rose giving me a splendid view of the earthshine portion of the disk. 
     As the Moon rose higher into the sky he decided to turn the telescope 
     onto it to the earthshine region of the Moon. He made it a practice 
     to examine this region of the Moon to monitor for craters that appear 
     to glow under this light. While observing he became aware of a black 
     spot located  in the sunlit portion of the Moon about 60 miles west of 
     the sunset terminator. At first he thought the black spot was a shadow 
     being cast by a large mountain or crater. When looking at his lunar 
     charts he could not locate any feature that would account for it. As he 
     continued to study the black spot he realized that it appeared darker 
     than any shadows on the Moon. It was at 4 June 1986 4:15 A.M. CDT or 
     9:15 U.T. when he first sighted the phenomena and it was at 4:25 A.M. 
     CDT or 9:25 U.T. that he realized he was seeing a lunar transient 
     phenomena event. It was at this time that he could start to see silvery 
     filaments or streaks in the black patch. Between 9:23 and 9:25 U.T. he 
     watched the black patch disappear. When the black spot had disappeared 
     he found that the location of the black spot was over the crater
     Reiner. he estimated that during the L.T.P. event that area covered by 
     the black cloud was approximately 40 to 50 square miles. He also had 
     examined other formations on the Moon during this event and none were 
     exhibiting the same phenomena witnessed over the crater Reiner.

     refractor, x267, seeing III, transparency average) observed that 
     Plato in general was normal in appearance, but the east rim was 
     showing a remarkable golden (yellow-golden) hue. This was a

     matched the gray of the crater. Within minutes the shadow line 
     looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a 
     pulsation in Plato during a lunar eclipse. He thought that this

     showed a grey column cutting across the central floor of the 
     crater from the west and then bisecting the eastern rim. All 
     detail inside is completely invisble. Some (but not all) of the 
     other images showed a more blurred view of this feature. It's 
     possible that this was a seeing ripple effect, or just the 
     natural appearance of shadings on the Moon at this time, however

2026-Jul-31 UT 06:24-08:03 Ill=97% Aristarchus observed by Moore_P on 1992-5-19

     On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, 
     x260) saw at 01:25UT an unmistakable red-orange glow on the south and 
     south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected 
     it easily. At 01:33UT the colour was barely visible. No TLP alert was 
     issued because the souther edge of Mons Pico also exhibited a hint of 
     colour, and anyway the seeing conditions were poor. Despite this no 
     other features revealed colour. The Cameron 2006 catalog ID=446 and the 
     weight=0. The ALPO/BAA weight=1. 


2026-Jul-31 UT 06:24-08:03 Ill=97% Mons_Pico observed by Moore_P on 1992-5-19

     On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, 
     x260) noted that the southern slope of Mons Pico had a tint of colour. 
     No other features revealed colour apart from Aristarcus, where a TLP 
     was going on. The Cameron 2006 catalog ID=446 and the weight=0. The 
     ALPO/BAA weight=1.
