2020-Aug-04 UT 23:43-01:30 Ill=98% Hahn observed by Hazel_N on 2012-1-9

     On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel 
     (Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max, 
     with 2x teleconverter, at f9, 1/320 sec, ISO 400  tripod 
     mounted, mirror up), A series of images were taken. The 21:06 one 
     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 
     for now this will be given an ALPO/BAA weight of 1.

     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

2020-Aug-12 UT 04:26-05:06 Ill=45% Plato observed by Morgan_P on 2009-6-16

     On 2009 Jun 16 at UT 03:20-03:40 P. Morgan (UK, 30.5cm reflector, x400, 
     seeing=6/10 and transparency=5/5) observed a large diffuse ashen-like 
     effect over the shadow filled floor of Plato. The effect was lighter 
     towards the south. Observer checked the effect with both left and right 
     eyes and it remained the same. Unusually no shadow spires from rim 
     moutain peaks were seen. A check for colour in the region effected 
     revealed none. As time progressed, terrestrial twilight encroached. A 
     sketch was made. The ALPO/BAA weight=1.

     On 1981 Oct 21 at UT 11:35-11:48 B. Hobdell (St Petersberg, FL, USA, 
     10" reflector) found that the south peak of Plato on floor glowed white 
     at 11:35UT, then a milky shade spread all aorind Plato's floor 
     (previously completely shadow filled). The needle like shadows started 
     to be indistiguishable through the sunlight (dawn on Earth). The cloud 
     like feature was washed out by daylight at 11:48UT and conformed to the 
     "white area except a tail that reached the cetre of Plato" Spurious 
     colour was not seen. The Cameron 2006 catalog ID=157 and weight=3.

     (Port Tobacoo, MD, USA) described in the NASA catalog as: "Color patch

     Aristarchus 1983 Aug 03 UT 0305-0400 Observed by R,Moseley 
     (Coventry, UK, 6" reflector, seeing II, Transparency very good). 
     At the start of the observation, the NE wall and immediate 
     exterior was the brightest area visible (this is normal) and 
     seemed tinged with a faint blue/violet. At 03:45 the impression 
     of colour was fading in the brightening sky, but by 03:55 the 
     colour was back again with a faint violet/purple surrounding the 
     whole formation from E clockwise to N. The observer found it 
     difficult to decide whether it was really a colour on the Moon, 
     or an optical illusion. ALPO/BAA weight=1.

     On 1977 Dec 08 at 04:04UT V.M. Chernov (Soviet Union) observed that the 
     south cusp was prolongated into Ashen light. This is the only occasion 
     where he had seen this effect on two successive nights. However a 
     similar effect was seen by F. Gruihuisen on 1840 Mar 5th and 6th. The 
     ALPO/BAA weight=1.


2020-Aug-21 UT 19:02-20:10 Ill=10% Aristarchus observed by Herschel_W on 1783-5-4 *

     William Herschel and Mrs Lind saw a red, 4th magnitude brightness, less
     than 3 arc sec in diameter. Herschel believed that he was seeing a 
     lunar volcano in erruption.


2020-Aug-23 UT 18:59-19:14 Ill=28% Aristarchus observed by Celis on 1970-7-8

     On 1970 Jul 08 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3" 
     refractor, x60, x100, x135, seeing=excellent) observed the following at 
     Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8 
     deg) than last nite. but not as bright as on the 6th. Pin pts. of light 
     very accentuated. The radial open hand extended fingers form not so 
     frequently, perhaps because of the larger crescent illum. now.". 
     The Cameron 1978 catalog ID=1266 and weight=3. The ALPO/BAA weight=2.


2020-Aug-23 UT 19:06-19:14 Ill=28% Cyrillus_G observed by Paynter_L on 1983-8-13

     Cyrillus G 1983 Aug 13 UT  20:17-20:59 L. Paynter (Radcliffe, 
     UK, 22cm reflector, seeing III or better, transparency good). 
     Cyrillus G was relatively bright and surrounded by a shaded 
     area. On increasing the magnification from x65 to x130 he became 
     aware of a diffused "carise" colouration, in and around the 
     crater. The colouration was similar though to other spurious 
     colour on the Moon, but unlike other areas affected by spurious 
     colour, was more diffuse and spread out and not so concentrated. 
     In view of some uncertainty by the observer, ALPO/BAA weight=1.

     On 1991 May 19 at UT 22:59 M. Cook (Frimley, UK, 12"? reflector, 
     seeing III-IV) noted that Censorinus was a dull greyish white in 
     colour and the apron was not diffuse. The Cameron 2006 
     catalog ID=426 and the weight=1. 


2020-Aug-24 UT 18:57-19:25 Ill=39% 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.

     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

     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

     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.

     Wratten 29 and 44A filters, Seeing II-III and transparency poor-

     Aristarchus 1963 Oct 30 UTC 22:00? Scarfe (Cambridge, UK) 
     observed a 30% enhancement at 540nm in the spectra of 
     Aristarchus. The Cameron 1978 catalog ID No. is 778 and weight

     30% enhancement at 540nm in the spectra of Copernicus. The
     Cameron 1978 catalog ID No. is 778 and weight is 5. The

     On 1989 Jun 17 at UT 06:33-07:16 R. Manske (Sun Prairie, WI, USA, 1" 
     refractor) sketched a nebulous spot near to Herodotus crater that at 
     06:49 (when he tried some filters out) was visile through red, blue and

     On 1789 Jan 10 at UT 00:00 Seyffer (Germany) observed "a lunar 
     volcano". Cameron comments that this must have been bright as it was

2020-Aug-31 UT 23:14-23:59 Ill=98% Aristarchus observed by Louderback_D on 1981-11-10

     On 1981 Nov 10 at UT 07:54-08:22 D. Louderback (South Bend, WA, USA,
