2025-Jun-01 UT 04:51-06:17 Ill=31% Earthshine: sporadic meteors

2025-Jun-02 UT 04:04-05:04 Ill=40% Limb observed by Challis on 1859-5-8

     Observations made by Challis of Cambridge, and N. Pogson of Hartwell, 
     both of the UK. Before the occultation, Saturn's rings were 
     distorted. A dark border was seen around the Moon. Just before 
     re-appearance a sea green colour was noticed. Cameron 2006 
     catalog extension  ID=5 and weight=2-5. ALPO/BAA weight=1.


2025-Jun-02 UT 04:04-04:41 Ill=40% Mare_Crisium observed by Kidger_M on 1975-3-18

     On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK, 
     60mm refractor, x36, very good conditions with a very sharp image and 
     the sky was almost perfectly clear apart from a very few small clouds). 
     In Mare Crisium it was observed that only a ray of Proclus could be 
     seen to cross the floor - normally there are at least four craters 
     visible inside mare Crisium on good nights and at least one being 
     visible under bad conditions. So despite it being very clear and the 
     image quality being good, the observer found it odd that no craters 
     were visible on the floor of mare Crisium. This is a BAA Lunar Section 
     report. The ALPO/BAA weight=2.


2025-Jun-02 UT 04:43-06:02 Ill=40% 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. 


2025-Jun-02 UT 05:42-06:36 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.

     On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a 
     10" reflector) observed Menelaus to have a deep red cloud that seemed 
     to surge upward from outside the southern edge of the crater wall and 
     disperse around the outside edge, spreading out on reaching Mare 
     Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch).

     On 1941 Jan 06 at UT04:00 Barcroft (Madera, CA, USA, 6" 
     reflector) saw an anomalous shadow in Arzachel crater. Cameron 
     1978 catalog ID=482 and weight=3. ALPO/BAA weight=3. 


2025-Jun-04 UT 04:06-05:02 Ill=60% Ptolemaeus observed by Firsoff on 1954-5-10

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

     Herschel 2005 Aug 13 UT 00:07-00:29 Observed by Daniel del Valle 
     Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting 
     configuration of shadows with umbra and penumbra. Effect seemed to

2025-Jun-04 UT 04:06-05:37 Ill=60% 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.


2025-Jun-04 UT 04:06-05:42 Ill=60% 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.


2025-Jun-04 UT 04:35-06:32 Ill=60% 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.


2025-Jun-04 UT 04:46-05:56 Ill=60% 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.


2025-Jun-04 UT 04:46-05:56 Ill=60% 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.


2025-Jun-04 UT 06:15-07:01 Ill=61% Alphonsus observed by Darling_D on 1990-5-3

     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.

     Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill-
     defined obscur. in blue photo in S. part of crater compared with 
     orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to 
     Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA 
     catalog ID #1250.


2025-Jun-04 UT 06:39-07:01 Ill=61% 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.


2025-Jun-04 UT 06:47-07:01 Ill=61% Alphonsus observed by Horowitz on 1967-8-13

2025-Jun-05 UT 04:17-05:25 Ill=69% Proclus observed by Darling_D on 1988-7-23

     On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12" 
     reflector, x150, seeing = 6/10) discovered that the dark area on the 
     floor of Proclus, seen earlier by UK observers was still present, but 
     less so (?) and the shape changed. When viewed through a green filter 
     it was less distinct. "Change with two other filters. Polarizer gave a 
     circular shape with a knot on SE side & W58 in White." The measured 
     brightness of Proclus was 9 on three sides and 8.5 on its west rim. The 
     floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus, 
     Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The

     deep red line seen at 1st contact with B-ring of Saturn. Nothing 
     unusual at A-ring contact. Persisted during occult. of B-ring. It 
     divided into 2 components & space between B-ring & globe cutting ring 
     into 2 disjointed ends persisted till dark limb passed onto globe of 
     Saturn, then a short red line corresponding exactly to chord of planet 
     disk defined by lunar limb. It increased in length as occult. 
     progressed. It suddenly vanished after 3/4 of globe had been occulted. 
     No afterglow at spot on limb, no irreg. at limb could be seen. Obs. 
     eliminates Saturn, telescope, & atmosp. as possible cause. Suggests 
     refraction from tenuous atm. of destructive interference of reflected 
     light from very small angle at limb, or diffraction of Saturn light 
     grazing limb". The Cameron 1978 catalog ID=1389 and weight=1. The

     the previously observed gray area was 1/3 of July 22 and V 
     shaped and fanned out across the floor. Could see hint of knot 
     seen before. Craters named in 7/23/88 (#319) were all normal 
     this time too". Is it possible that this report refers to the 
     crater "Gray" rather than "Proclus" as the column field suggests 
     in the Cameron catalog? The Cameron 1978 catalog ID=333 and 
     weight=5. The ALPO/BAA catalog weight=2.


2025-Jun-06 UT 06:18-07:06 Ill=78% Bullialdus observed by Findlay_MW on 1975-3-22

     detected "purple"in the vicinity of Aristarchus crater and this was 
     stongest on the north and north west external rims, however there was 
     no "violet glare"from inside the crater. However the region of the 
     central peak was very bright - though he could not detect the central 
     peak. The brightness of the TLP was 4.5 and it should normally be 3 
     (nimbus area). Near the "big plain"it was 7. The chromatic aberation 
     seen on the crater. There was also violet on the northen wall of

     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
