     On 1970 May 08 at UT 23:00-23:30 Celis (Quilpue, Chile, 3" refractor, 
     x60, atmosphere turbulent) observed in the Aristarchus region a clear 
     line(?) and several star-like points. Cameron suspects atmospheric 
     effects due to low altitude and turbulence? The Cameron 1978 catalog 
     ID=1259 and weight=1. The ALPO/BAA weight=1.


2026-Jun-18 UT 01:35-01:59 Ill=12% Aristarchus observed by Darling_D on 1989-4-9

     On 1989 Apr 09 at 02:13 was seen to be not very bright in binoculars, 
     despite visibility of Earthshine in general as being exceptional. 
     Darling confirmed this at 02:31UT, though it was quite bright in a 
     17" reflector,but Herodotus could barely be seen. Weier claimed to be 
     able to see Aristarchus with the naked eye. At 02:08 the brightness was 
     found to be 5.0 for several measurments. The observing team ware from 
     the Maddison Asgtronomical Society, WI, USA. The Cameron 2006 catalog 
     ID=359b and he weight=3. The ALPO/BAA weight=2.


2026-Jun-18 UT 01:35-02:17 Ill=12% Gassendi observed by Graham_F on 1990-4-28

     On 1990 Apr 28 at UT 00:00-00:30 F. Graham (Marshall TWP, OH, USA, 6" 
     reflector) during a failed attempt to observe the occultation of X6493 
     that was thwarted by clouds, noticed that Gassendi was "Gass,>>,>Aris 
     or anything else". The crater had a "milky lustre". It is possible that 
     another occultation observing group may have a video of the Earthshine 
     at this time. Darling (Sun prairem WI, USA, 20x50 binoculars) could not 
     see Earthsine, though the sky was bright at the time. The Cameron 2006 
     catalog ID=402 and the weight=0. The ALPO/BAA weight=1. 


2026-Jun-18 UT 02:11-02:17 Ill=12% Gassendi observed by Graham_F on 1990-4-28

2026-Jun-19 UT 01:35-02:50 Ill=21% Boussingault observed by Schmidt_J on 1860-4-24

     Boussingalt 1860 Apr 24 UT 20:00? Observed by Schmidt (Athens, Greece, 
     7" refractor) "Noted weak glows on the crater he tho't prob. due to 
     wall reflections on floor" NASA catalog weight=0 (very unlikely to be a 
     TLP). NASA catalog ID #132. ALPO/BAA weight=1.


2026-Jun-19 UT 02:41-02:50 Ill=21% Cassini observed by Andrenko on 1937-2-14

     Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron 
     1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,


2026-Jun-19 UT 02:42-02:50 Ill=21% Aristarchus observed by Blair_G on 1980-11-11

     On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at 
     17:35UT immediately noted that the Earthsine was extremeley bright. All 
     large detail easily seen on unilluminated disk. 17:38UT a definite pale 
     reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be 
     getting larger and more intense west (IAU) side. Attempted to contact 
     other observers. 17:40UT Aristarchus still had a bright central peak. 
     17:50UT fading a little from the west (IAU). 18:00UT slight revival in 
     brightness. 18:15UT effect still visible when Aristarchus set behind a 
     high western horizon. The two sketches supplied show the illuminated 
     region around the crater with extension to the west (IAU). P. Foley 
     (Kent) found thatAristarchus was bright enough in Earthshine to be seen 
     with the naked eye. Telescope in operation at 18:00UT and the entire 
     Aristarchus region was bathed in violet/rose colour with what appeared 
     to be a strong ray extending to the west (IAU). Detail could be clearly 
     seen inside Aristarchus crater such as the central zone, west and north 
     wall and rim in relief from point southeat to northwest. CED measure 
     0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave 
     a measure in red. Observation ceased by 18:32UT as the Moon was very 
     low. ALPO/BAA weight=3. 


2026-Jun-19 UT 02:16-02:52 Ill=21% Earthshine: sporadic meteors

2026-Jun-20 UT 02:16-03:17 Ill=31% Earthshine: sporadic meteors

2026-Jun-21 UT 01:35-02:43 Ill=41% W_Limb observed by Webb_TW on 1855-6-20

     In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of 
     twilight (Cameron says also seen by Gruithuisen, Henry and others at 
     times). Webb gives a low weight to his own observation, saying "for 
     want of better optical means". The Cameron 1978 catalog ID=130 and 
     weight=1. The ALPO/BAA weight=1. 


2026-Jun-21 UT 02:08-03:35 Ill=41% Mare_Imbrium observed by Unknown_Italian_Observers on 2012-3-28

     On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian 
     observers, reported on an on-line formum that they had 
     independently seen a distinct glow with a comma/drop shape. 
     One of them moved the Moon and the glow moved with the Moon. 
     It is uncertain how experienced the observers where. A chart 
     was provided which shows the lcoation of the glow in the 
     western side of Mare Imbrium. It is just possible that this 
     was Aristarchus in Earthshine, though that is very slightly 
     further west and south than the observers reported. ALPO/BAA 
     weight=1.


2026-Jun-21 UT 03:03-03:35 Ill=42% Menelaus observed by Grego_P on 2012-3-28

     On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm 
     refractor, x132) observed a patch of light just inside the NW 
     rim of Menelaus on the shadowed wall or floor. Computer 
     visulaiztions of the illumination conditions using a digital 
     elevation model failed to produce this effect. ALPO/BAA weight=3.


2026-Jun-21 UT 03:12-03:35 Ill=42% Eudoxus observed by Trouvelot on 1881-5-4

     On 1881 May 04 at UT 20:00? Trouvelot (Meudon, France) 
     observed an unexplained light inside Eudoxus crater. The 
     Cameron 1978 catalog ID=222 and the weight=3. The ALPO/BAA 
     weight=3. 


2026-Jun-21 UT 02:16-03:37 Ill=42% Earthshine: sporadic meteors

2026-Jun-22 UT 03:09-03:51 Ill=52% Pitiscus observed by Slayton_G on 1981-9-6

     Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make 
     it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA, 
     8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright 
     glow in the crater that appeared to move. Observer also reported seeing 
     it visually noting that it looked gray with a tinge of red. For further 
     information see p266 of Sky & Telescope (1991, March). Note that 
     Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day 
     later. I will use this date and time from now on. The Cameron 2006 
     catalog ID=152 and weight=5. The ALPO/BAA weight=3.


2026-Jun-22 UT 03:34-03:51 Ill=52% Theophilus observed by Marshall_KP on 1982-9-24

     In 1982 Sep 24 at 22:45-23:40 K. Marshall (Medellin, Columbia) saw in 
     Theophilus an obscuration on the south west wall close to Cyrillus and 
     furthermore it had a red / mauve colouration (seen best in a 12mm Ortho 
     eyepiece). Through a Wratten 15 yellow filter the region was quite 
     bright. At23:40UT the obscuration faded. There was plenty of detail in 
     the region between Theophilus and Cyrils. The Cameron 2006 catalog ID=
     184 and the weight=3. The ALPO/BAA weight=3. 


2026-Jun-22 UT 03:45-03:51 Ill=52% Posidonius observed by Houdard on 1915-4-21

     On 1915 Apr 21 at UT 1800? Houdard (France) noticed a special 
     occurrence south of Posidonius which he took as evidence of water 
     vapor. The Cameron 1978 catalog ID=351 and weight=3. The ALPO/BAA 
     weight=2.


2026-Jun-22 UT 02:17-03:53 Ill=52% Earthshine: sporadic meteors

     Flash seen in Ptolemaeus (A?) - possibly a meteor. Cameron 1978
     catalog weight=1. Cameron 1978 catalog ID=863.


2026-Jun-23 UT 01:36-02:41 Ill=62% Proclus observed by Dean on 1970-7-11

     Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson, 
     Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw 
     something in Proclus, alerted Jamieson who saw nothing unusual 
     at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw 
     Proc. fluctuate. Red & blue filters showed some reduction in 
     brightness. E. edge showed darkening, but not as dark as in 
     shadows. 10 min later, returned to normal. (Sparks confirmed 
     Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA 
     weight=3.


2026-Jun-23 UT 01:36-02:41 Ill=62% Secchi observed by Dean on 1970-7-11

     1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson  
     saw nothing unusual, but found instead that Secchi was quite bright.  
     NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA 
     weight=1.


2026-Jun-23 UT 01:36-02:56 Ill=62% Eimmart observed by Louderback_D on 1983-9-15

     On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA, 
     8" reflector and 3" refractor, seeing poor) found that the west wall of 
     Eimmart was unusually bright (8.3) and apparently it was almost as 
     bright as the "WEBS(of Aris?) at its brightest". The crater was 
     apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
     228 and the weight=3. The ALPO/BAA weight=2.


2026-Jun-23 UT 01:36-02:10 Ill=62% Mons_Pico observed by Adee_J on 2008-4-13

     2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw 
     Mons Pico to be incredibly bright. Adee reported naked eye visibility, 
     though this does not show up in later CCD images. Jarwaski saw another 
     nearby Mt very bright as well. This has been assigned an ALPO/BAA 
     weight of 1, though I suspect it is just normal for Pico to get quite 
     bright at sunrise.


2026-Jun-23 UT 01:36-02:15 Ill=62% Montes_Apenninus observed by Armitage_J on 2008-4-13

     Patches of brightness seen in the area between craters Aratus and Joy.
     Seemed to the observer to be perhaps slightly brighter than one would
     expect - the observer thought that their observation only barely
     constitured a TLP but decided to send the report in anyway. This
     has been assigned an ALPO/BAA weight of 1.


2026-Jun-23 UT 02:34-04:03 Ill=62% Purbach observed by Osawa on 1970-4-14

     Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima,

     On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing 
     steady) observed a point of light inside Alphonsus just to the north 
     of the central peak, along the "center ridge". It was seen again, half 
     way between the central peak and the noth west rim - along the ridge. 
     All other features were normal. The Cameron 2006 catalog ID=403 and the 
     weight=3. The ALPO/BAA weight=3.


2026-Jun-23 UT 03:12-04:03 Ill=62% Moon observed by Mattingly on 1972-4-21

     On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit 
     around the Moon, using his naked eyes) saw a bright flash from below 
     his horizon on the lunar farside (approximate longitude=180 deg). he 
     was dark adapted at the time. However no sesimic event was recorded and 
     so Cameron suspects that this was not a meteor impact but a cosmic ray 
     striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The 
     ALPO/BAA weight=3.


2026-Jun-23 UT 03:16-04:03 Ill=62% Alphonsus observed by Horowitz on 1967-8-13
