2019-Apr-14 UT 23:10-23:19 Ill=74% Moltke observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clear what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) 
     noticed that Moltke was very bright with a fuzzy violet hue - he had 
     never seen it like this before. Cameron 2006 catalog extension TLP ID=

2019-Apr-14 UT 23:10-23:19 Ill=74% Plato observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clerr what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) saw 
     initially no craterlets in Plato, despite the Moon being at a high 
     altitude. At 01:45UT the northwest corner of Plato was red. Again no 
     other craterlets showed. He found the surrounding wall to be too bright 
     and this was confirmed by Crater Extenction Device readings and had 
     problems focussing on the crater. By 02:00-02:50UT he noticed 
     variability in the visibility of the craterlets. By 03:48UT the central 
     craterlet was much brighter than before and the crater doublet had 
     brightened but the southern craterlet was still invisible. Cameron 
     comments that Marshall was a very experienced observer. A. Cook (of 
     Frimley, UK) obtained a photodiode line scan image of Plato. The 
     brightness of the north west wall was brighter than the bright area on 
     the west wall. Marshall and Mosely both saw a dark area on the floor of 
     Plato close to the south wall (from clock position of 11 o'clock. There 
     was a prominent white spot on the floor and the central craterlet was 
     seen, but only under good conditions. Mosely does not discuss the west 
     and north west wall brughtnesses that were seen earlier by Cook and 
     Marshall. Cameron 2006 catalog extension TLP ID=240 and weight=2.

2019-Apr-15 UT 22:57-00:38 Ill=83% Daniell observed by Madej_P on 1982-4-4

     On 1982 Apr 04 at UT 23:30-00:25 P. Madej (Huddersfield, UK, 7cm 
     refractor & 16cm reflector) noticed the TLP in his refractor 
     first of all at x25. So stepped up the magnification to x111 and 
     found the crater brightness not what he was expecting. He tried 
     different filters but found no difference in brightness. With 
     the 16cm reflector however some changes in brightness were 
     dected. The crater has a very pale yellow colour and it was 
     slightly darker than Lacus Somniorum. P. Foley tried to confirm 
     at 00:09 but the crater looked normal then. The Cameron 2006

     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in

     Louderback observed that the south west wall was a creamy deep yellow.
     There was also strong fluorescent blue on the west wall of the Cobra
     Head - Schroter's Valley area and this was similar to the violet glare
     seen on Aristarchus at times. Violet was seen between Aristarchus and
     the Cobra Head. Seeing coditions were poor. Brightening of a point
     near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
     (Cameron concludes that this was not due to the Earth's atmosphere).
     A 0.2 step drop in brightness was seen on point A (twin spots).
     Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.

     A bit more of a detailed report is as follows: "Upon the 13th of May, 
     1870, there was an "extraordinary display," according to Birt: 27 
     lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in 
     Brighton. Atmospheric conditions may have made this difference, or the 
     lights may have run up and down a scale from 4 to 28. As to 
     independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this 
     display, that only the fixed, charted points so shone, and that other 
     parts of the crater were not illuminated, as they would have been to an 
     incidence common throughout.(30) In Pratt's opinion, and, I think, in 
     the opinion of the other observers, these lights were volcanic."

2019-Apr-19 UT 23:54-00:53 Ill=99% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual.

     Louderback, of South Bend, WA, USA observed a bright area over
     Mons Anguis and Eimmart - it resembled a comet and had a bluish 
     colour and varied in brightness. The colour was confirmed as it 
     was not seen in a red filter but could be seen in blue and white 
     light. Other features were checked but did not show anything 
     similar although a violet glare was suspected in the blue filter. A
     sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.
     Noted that the area around Eimmart appeared opaque at times and less so
     at other times. At 08:52UT the phenomenon was seen again. On May 2nd 
     a bright spot was still seen in the region but it was not changing 
     dimensions. During the observation on Apr 30th the atmospheric
     transparency was excellent. A 2.5" refractor was used. Reference:

     Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK, 
     21cm Newtonian, x217, seeing very good). Flickering colours seen 
     on the north field of Alhazen Alpha mountain. Above UTs 
     estimated by the observer, but the duration of the effect was 3 
     minutes. Colouration centred on the hills that run north to 
     south between Mare Anguis and Mare Crisium. The colour 
     alternated from east to west about 2 or 3 times per second. The 
     colour was not apparent to the north or south, or indeed on any 
     other features. Telescope field of view moved, but effect stayed 
     in the same place on the Moon. Moon't terminator scanned for 15 
     minutes afterwards, but the effect did not recur. The colour 
     seen was mostly red, with a band of orange, and a strip of 
     yellow nearest the hills, the proportions being 6:2:1. The bands 
     seemed to arc up steep above the Moon's surface and flatten out 
     over the mare surface either side of the hill features. No 
     filters were used in the observation. Observer suspects some

     Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25" 
     reflector, x86 & x144) observed it to be a strikingly brilliant 
     'splodge' seen in the mostly shadow filled interior of 
     Cleomedes, and around this splodge was a faint halo extending 
     symetrically in an eastwards direction. The splodge was the 
     mountain Cleomedes Alpha. Strangely no shadow from the mountain 
     was seen to be cast onto the halo on the east. Observer alerted 
     other observers by phone, and upon returning to the scope found 
     that the splodge had faded in brightness and continued to fade 
     over the next hour as one would expect from a mountain at 
     sunset. Some heavy spurious colour was present. J. Cook & M. 
     Cook (Frimley, UK) observed at 22:20-22:25 and found the bright 
     splodge, but no halo. M. Cook re-observed later and confirmed 
     normal fading of splodge. Roscoe observed from 00:30UT next day, 
     but by that time Cleomedes Alpha had set and was no longer 
     visible in the shadow filled floor. S. Beaumont had observed 
     earlier at 20:00 but had recorded all as normal in Cleomedes.

2019-Apr-25 UT 08:00-09:57 Ill=65% Cabeus observed by LCROSS on 2009-10-9

     On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage, 
     followed 4 min later by the observation spacecraft, is due to impact 
     into a the crater Cabeus in the hope of kicking up some dust and 
     possible frozen volatiles. Note that this description is intended for 
     observers on the date of impact and it is doubtful that any new
     science could be achieved by re-observing the same area months
     after the impact. If you are observing on the date of impact, then 
     please observe around 11:00-11:04UT and ignore the predicted times in 
     the headings. However this report is included as techniqcally
     if something is seen it is a TLP, albeit man-made! For those observing 
     on the date in question here are a few observing tips to maximize 
     the science of your observations: (1) If you are imaging, then please 
     try to obtain images before the impact because you can then subtract 
     these from images taken during the impact and hence show up faint 
     changes that you might normally miss. (2) If you have a spare scope and 
     camera,use this to observe through filters such as UBVR or I, or if you
     have narrow band interference filters, try observing in
     say Hydrogen Alpha, Methane, OH, or indeed any volatile that you 
     might expect to see in a comet (the main source of water at the poles).
     (3) Please try checking the area long after the impact, just in
     case other effects might trigger a TLP. (4) Please go to some trouble 
     to ensure accurate timings- these will be essential in order to 
     understand the sequence of events - assuming any are seen. Timings can 
     be obtained using a short wave radio or via a GPS. Note that you should 
     always use UT or UTC. (5) Please send any observations that you make 
     into the upload section of the LCROSS campaign observers web site. If 
     you belong to an astronomical society e.g. BAA or ALPO, then do please 
     send copies of your observations to the Lunar Sections of your society

     the planned impact.


2019-Apr-25 UT 09:08-10:40 Ill=65% Cabeus observed by Grego_P on 2009-9-9

     On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
     III) suspected a flash south of Cabeus, just beyond the terminator.
     It was not bright, and lasted a fraction of a second. Thinks it might
     have been illusory as he saw some fainter flashes (cosmic rays?) 
     during that nights observing session. ALPO/BAA weight=1.


2019-Apr-26 UT 07:55-09:51 Ill=56% Aristarchus observed by Cowan on 1974-9-8

     Aristarchus 1974 Sep 08 UT 04:45-06:30 Observed by Cowan and Johnson 
     (Dublin, TX, 8" reflector, x59, x152, S=7) "Saw a bright luminous, 
     blue, misty cloud on th NE rim. Obscur. for 1st hr. then gave way to 
     pink & features became vis. Cloud was tear-drop shape. No movement to 
     glow. Pink cloud glowed too. Very tenuous by 0130h. (Nakamura says 
     there were no seismic events within several hrs. of this time). Another 
     person saw it without being advised as the where it was." NASA catalog 
     weight=5. NASA catalog ID #1393. ALPO/BAA weight=4.


2019-Apr-26 UT 09:48-11:00 Ill=55% Alphonsus observed by Brook_C on 2009-9-11

     On 2009 Sep 11 UT00:15-00:20 and 01:00-01:05 C.Brook (Plymouth, UK, 5" 
     O.G., x100, seeing tremourlous but definition improving over time) 
     noticed that the central peak(s) in Alphonsus were brightening 
     gradually. No effect was seen earlier at UT23:30-23:35. One presumes
     that the effect also occured between these two observing times?
     The observer suspects that this was not a TLP, but is uncertain.
     ALPO/BAA weight=1.


2019-Apr-27 UT 07:05-09:02 Ill=46% Wargentin observed by Gaudibert_CM on 1878-10-18

     On 1878 Oct 18 at UT 21:00? Gaudibert (France?, 4"refractor) observed 
     Webb's white spot on SW border of Wargentin to be brilliant, however 
     this had vanished by Oct 19. The Cameron 1978 catalog ID=204 and the 
     weight=4. The ALPO/BAA weight=3.


2019-Apr-27 UT 08:15-10:11 Ill=46% Tycho observed by Carvalho_F on 2006-1-22

     Tycho 2006 Jan 22 UT 06:34-06:36 Observed by Fabio Carvalho 
     (Assis, Sao Paulo Brazil, 25cm f/6 Newtonian) "Green colouration 
     seen on a rim of Tycho, effect remained visible for only 2 
     minutes. Attempts to image it shortly afterwards failed as it 
     had finished by then" An REA-Brasil observational report. 
     ALPO/BAA weight=3.


2019-Apr-27 UT 08:59-10:39 Ill=46% Tycho observed by Cook_MC on 2009-9-11

     On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
     x80 and x190, seeing II and transparency moderate-poor) observed
     pink on the north west rim of Tycho and green-blue on the inner
     SW rim. No sign of colour elsewhere on the Moon except for the
     S-E rim of Plato that was red. The Moon was about 20 deg in altitude
     at the time. The effect had gone by the end of the observing period. 
     A simulation of spurious colour in different directions 
     was generated by the BAA Lunar Section and found to possibly account 
     for these colours, although there should have been some strong colours 
     seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.

     reflector, x35, x52, x73 and x110, seeing IV-V, transparency very 
     good). Note that the observing date was also written as Jul 14th in the 
     original report? Puiseaux was very clear in white light, but could not 
     see the cenrtral peak. The central peak though was visible through a
