On 1969 Oct 16 at UT 00:00-00:30 Celis (Quilpue, Chile, 3" refractor, x60, seeing=very good) observed brilliant points at 8.5 magnitude in Aristarchus. This was not seen the next night or the one after, nor after 5 days age. The Cameron 1978 catalog ID=1204 and weight=1. The ALPO/BAA weight=1.
On 1972 Dec 10 at UT21:11 Schmitt, whilst orbiting the Moon on Apollo 17 saw a flash in Grimaldi. When questioned by Cameron upon return to Earth, he said that he was dark adapted at the time and was unable to say whether it was a cosmic ray or an impact flash. Cameron says that there have been many similar reports in the past from Earth-based observers e.g. TLP report No. 1167). The Cameron 1978 catalog ID=1352 and weight=3. The ALPO/BAA weight=2.

On 1983 Feb 18 at 19:00?UT P.W. Foley (Kent, UK) noted that Toricelli B was steel blue in colour and this spread 10-15 miles outside the crater. This was odd because Torricelli B was only 6 miles in size. Cameron 2006 catalog extension ID=205 and weight=3. ALPO/BAA weight=2.
On 2012 May 26 UT21:21 J. Moeller (Syracuse, NY, USA, using a Konica Minolta DIMAGE Z5 digital camera, f/7.1, 1/250 sec exposure, ISO-50, 69mm focal length, digital zoom x3) captured a hand held image of the Moon in daylight.

Cassini E 2002 Dec 11 UT 16:30-18:46 Observed by Knott (Liverpool, England, 216mm Newtonian, x216, red and blue filters used) seeing III, transparency good) "Observations carried out of the area extending from the Alpine Valley to the Crater Cassini. At 17:12 a pin point bright flash was seen NW of the rim of the crater E in white light. A 2nd pin point flash was also seen at 18:18, this time thru a blue filter. The 2nd flash was also seen on the NW rim of the crater E. The observer does not think this was a TLP as the seeing was III, but the flash was so bright as to be startling. Other peaks within the Alps were bright but were much less so in red and ble filters, where the rim of the crater E. NW edge was very bright in all filters, including white light. Incoming cloud prevented further observation." BAA Lunar Section report.
On 1997 Apr 14 at UT 20:00-22:00 F. Paolo (Legnano, Italy) photographed a lunar flare on the lunar limb.

On 2003 Apr 10 at 00:40UT a GLR observer G. Jasmin (Quebec, Canada, using a 10" F-10 Schmidt Cassegrain) took a photograph of Alphonsus crater on Kodak 400ASA film with an exposure of 1/30th sec. There was a light visible (diameter 10 km) inside Alphonsus and the effect was present for 5 minutes. The observer commented that they have seen a light in this crater many times before, but never as long as 5 minutes. This report was submitted to the GLR group in Italy. The ALPO/BAA weight=2.
Thaetetus 1952 Dec 24 UT 20:00? Observed by Moore (England?) "Bright spot, hazy line of light" NASA catalog weight=4. NASA catalog ID 556. ALPO/BAA weigh=2.

On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan, Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10- best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac area a series of fiery sparks (dot like with tiny rays), slightly elongated with the multitudinal rays orientated towards the south west direction. The colour was mostly red, with some yellow. The final flash was the most clear. The TLP was tiny in area, but "was distinctly bright against any other object on the Moon". The positional uncertainty of the location of the spark effect was approximately +/- 150 km, based upon an examination of an atlas afterwards. Just prior to the spark effect, something dark, small and fuzzy (only just discrnable to the eye, through the eyepiece) was seen to pass from the west across the Moon in a slight curve, round the surface of the Moon to the east (post observation estimate: seen for 3.5 sec and covered roughly 8% of the lunar diameter in that time). The area of the dark object was comparable in size to (or slightly less than?) craters such as Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the limits of vision of the scope used. The location of the flash was not exactly at the same location as the dark object passed across, but gave the impression of starting from it? A back of the envelope calculation of the lunar diameter covered in the time quoted gives an approximate speed (at the lunar distance) of 80km/s or on the very high end of typical meteor streams that pass by. At closer distances, and recalculated velocities, it is unlikely to be a satellite in low Earth orbit (20m/sec at 100km distance), but could perhaps be a bird or insect at a few km range? So was this dark object something in our atmosphere by chance passing across the field of view close to the time of the TLP flare or was at the lunar distance and related to the TLP? Incidentally, no attempt was made during this observation to move the scope to check that the TLP remained stationary against the Moon. The ALPO/BAA weight=2.
On 1988 Feb 25 at UT20:00? P.W. Foley (Kent, UK, 12" reflector) found that Aristarchus was very bright (especially in the UV end of the spectrum) despite other features not being seen in Earthshine. The cameron 2006 catalog ID=318 and the weight=1. The ALPO/BAA weight=1.
Linne 1868 Jul 28 UT 20:00? Observed by Tacchini (Palermo, Italy) "Shadow not so marked-had a light penumbra, indicated a feeble cavity. Other craters had a black shad.

On 1995 Sep 03 at UT19:40-20:15 P. Moore (Selsey, UK, 15" reflector at x400) observed that the floor of Plato was much darker than he would normally expect and futhermore no interior craterlets were seen. there was however a white patch that was barely visible at the location of the central craterlet should have been. G. North (UK) attempted to observe nut the Moon was too low and seeing terrible. F. Doherty reported Plato normal. Cameron 2006 catalog ID=475 and weight=3. ALPO/BAA weight=1.
On 2010 Aug 19 at UT 00:50-01:02 J.Albert (Lakeworth, FL, USA, C11, Transparency 3, Seeing 7-8, 86F and very humid. Oberver checking out repeat illumination condition appearence for Tycho concerning LTP #468 in the 1978 Cameron catalog. Did not see the effect from the original TLP report, but did see, immediately at looking at Tycho a very faint hint of redness in a pencil thin arc (< 1/4 circumference of the rim) confined to the top of the rim of the well-lit north east wall. Coloured arc similar in thickness to Rupes Recta, but not as sharply defined. The outer (E) edge was perhaps sharper than the inner edge. The redness was more on the inside of the top of the rim. The outside of the rim was bright white. This effect was seen in three different eyepieces, at 311x, 224x and 400x. Checked for the effect on other craters nearby but could not see this effect anywhere else. The colour had dissapeared by 01:02UT. The fade took about 1-2 minutes. Observation of Tycho continued until 01:06UT, but all seemed normal. Quick checks were made again on Tycho periodically until 02:50UT but the colour was not seen again. ALPO/BAA weight=3.
Plato 1949 Mar 09 UT 02:00-03:00 E.J.Reese (6" reflector x240) and one hour later T.R.Hake (5" refractor x300) both unable to see any detail on the floor of Plato, despite both being able to see a "difficult to see" cleft near to the crater Connon. Reese was able to see detail under similar illumination back in 1948 and 1947 and saw the floor craterlets in Plato clearly then. ALPO/BAA weight=1.
On 1989 Feb 15 at UT 03:15-03:30 M. Dixon (Palenque Ruins, Mexico, 7x35 binouculars) observed a point of light that was very bright in or near Mare Humorum. It was visible for 5 minutes then vanished. The Cameron 2006 catalog ID=353 and weight=1. The ALPO/BAA weight=1.
On 1964 Feb 22 at UT 05:00 Harris (Whittier, CA, 19" reflector, x100) observed the appearance of a ring to the south east of Ross D. Cameron says that 7 persons have seen this over a 2.5 year period. The Cameron 1978 catalog ID=801 and weight=1. The ALPO/BAA weight=1.

On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" refractor, x90, seeing conditions: "at,. boiling") noted a coloured area on the west wall of Copernicus that was unusual in appearance - however other craters along the terminator had a similar effect. There was also a "dazzling bright spot on the E. rim and he witnessed 6 flashes from the lighted part of Copernicus over a very short time interval. Cameron comments that the colour may well have been dur to chromatic aberation because a refractor was used. The Cameron 2006 catalog ID=408 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. bright interior uniform gray". The Cameron 2006 catalog report is slight unclear as the description for thnis 1990 Aug 30 TLP also includes Copernicus and Censorinus in the list of TLP craters. So one description which might refere to Copernicus, could possibly have been meant for Proclus, namely: "Dazling bright spot on E rim. Rotated eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog ID=408 and weight=0. The ALPO/BAA weight=1.
Atlas 1966 Dec 21 UT 17:10 Observed by Andre (Belgium, 3" refractor) "Bright spot on SE part of floor, not seen in photo on 12/18/66" NASA catalog weight=2 (low). NASA catalog ID #1003.

On 1980 Jul 22 at UT20:08-21:50 G.North (Sussex, UK, 8" reflector, x144 and x207, seeing III-V and transparency fair) suspected an obscuration on the north and north west wall. The effect came and went. May have been due to seeing and image contrast? Cameron 2006 catalog ID=101 and weight=1. ALPO/BAA weight=1.
On 1990 Jan 07 at UT 20:20-20:58 G.North (Herstmonceux, UK) thought that he detected dullness in Torricelli B crater - Cameron comments that this cannot be shadow). The Cameron 2006 catalog ID=386 and the weight=3. ALPO\/BAA weight=2.
Plato 1971 Oct 30 UT 19:35-20:55 E.Watkins (Braintree, UK, 4.5" reflector, x45,x150, x225), thought he saw a faint patch at 19:35 and it still was visible at 19:40. At 19:50-19:55 he saw what may have been the remainder. At 20:55 he noticed a shadow in the area. ALPO/BAA weight=1.

On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159) observed an "anomalous black bar across Aris. Nearly digonal to terminator." The nearby crater Prinz had curious shadow patterns, perhaps related to the rising sun projecting shadows from the eastern rim and "reflected down"? "At 0224 W wall had a break in it & a diffuse glow where it should not be. Manske thinks it was Earthshine effect. At 0305 Weier saw Manske's bar - with diffused light and flicker like an aurora - like a gas with electric charge. At 0325 saw a strange glow in Aris. but may be due to atm. though thought it to be a LTP. Darling had never seen such effects before (flickering implies a medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The ALPO/BAA weight=3.
On 1984 Jan 14 at UT 20:00 P. Moore (Selsey, UK) observed that Aristarchus was brighter than it normally is at sunrise. No quantitative measurements were made though. The Cameron 2006 catalog ID=238 and weight=3. The ALPO/BAA weight=1.
On 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144 and x207, seeing=III-V and transparency=fair) found that the interior shadow was a light grey. BAA TLP coordinator (Foley) suggests that this was light reflecting from the illuminated walls? Cameron 2006 catalog TLP ID=102 and weight=1. ALPO/BAA weight=2.
Aristarchus visible just past terminator. West wall was brighter than normal. Bright flash seen in/on NW wall - apparently in the same place as Pedler's May 17th sketch.

ALPO/BAA weight=3.
Blanco, J. Vidal, of Gijon, Spain (3" refractor x72) noticed an unfamiliar very bright center near to Encke. Cameron suspects that this was Encke B crater on the basis that it is a prominent small crater near to Encke. Cameron 2006 catalog extension ID=410 and weight=2. ALPO/BAA weight=1.
In 1949 Nov 03 UT 01:06 J.Bartlett (3.5" refractor, x100) noted that the floor of Herodotus was very dark, the east wall was very bright, and the floor contained a central bright peak. The BAA/ALPO weight=3.
Crick of Belgium noticed obscuration on a bright spot on the south east wall. This spot was quite prominent through a red Wratten 25 filter. The floor was very dark. Other craters were checked and were normal. A sketch was supplied and the position was the same as in other earlier reports. Cameron 2006 catalog extension ID=60 and weight=3. ALPO/BAA weight=3. 6" reflector used. Seeing=II and transparency=good.
M. Cook of Frimley, "NE ray distinct & also floor E of it, not distinct as on Dec 13 & Jan 11, while March 10, 11 & 12 seen by Price, North, Peters, Foley & M Cook, where rim was clear and sharp." - quote from the 2006 Cameron Catalog extyension - TLP ID=297 and weight=5.

Plato 1906 Mar 07 UT 22:00? Observed by Fauth (Germany? 6" refractor) "Color (brightness?) greatly enhanced as on the previous nite" NASA catalog weight=3 (average). NASA catalog ID #324.
On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector, x360 and x400) found an area just south east of the central peak (and upto the wall) to be quite dark in blue light, but normal brightness in red light or in white light. All other features were normal colour- wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103 and weight=4. ALPO/BAA weight=3.
Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore (Sussex, UK) saw the wall as normal. However Cameron points out that Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely (Covington, UK) at 22:10 UT noticed a brightening on the East wall and at 01:10-01:25 UT suspected that the interior had a weak yellow-green cast to it. Cook (Frimley, UK) states that orange colour was within the interior crater, but green beyond the east rim at the 9 O'Clock and the south east corner to floor blue/mauvre beyond the northern rim NW/WSW. Foley sstates that orange and blue/mauvre might be spurious colour, but green one cannot get this way. Cameon suggests chromatic aberatons as a possibility but thinks that the observers concerned were experienced enough to recognize this if it were the cause. Cameron 2006 catalog extension ID=239 and weight=0. Moore used a 15?" refletor and Foley used a 12" refletor. Mosely experienced II seeing and good transparency. Cook had III seeing and also good transparency. P. Grego made an observation this night too. The ALPO/BAA weight=2.

Plato 1981 Jun 15 UTC 21:30 Observed by Amery (Reading, England, 25cm reflector, seeing Antoniadi IV-V) At the 4 O'Clock position on the North West corner?, there was a dark smudge which reached from the floor across and over the wall and onto the terrain outside the crater. Foley, alerted by Amery, saw a dark show-like patch in the crater's north west corner, again lying across the rim. 2006 Cameron catalog extension ID=148 and weight=4. Foley used a 12" reflector and seeing was III-V. ALPO/BAA weight=3.
Plato 1870 May 13 UT 22:00? Observed by Pratt (---), Elger (Liverpool, England), (Gledhill (Brighton, England) "Extraordinary display of lights. 27 seen by Pratt, 28 by Elger, only 4 by Gledhill. (independ. confirm. ?" NASA catalog weight=5 (very good) NASA catalog ID #168. 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." ALPO/BAA weight=4.

On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the Aristarchus area - P.Grego upon examining this comments that he thinks that Schiaparelli crater looked "muted in brightness -- it is normally quite bright to look at". Though Grego comments that it might have something to do with the image processing aplied to the image. The ALPO/BAA weight=1.
Madler 1940 Sep 16 UT 02:10 Observed by Haas (New Mexico? USA, 12" reflector?) "Bright spot on S. rim was I=5.8 comp. with 8.9 on Aug 17 (see #470)." NASA catalog weight=4. NASA catalog ID # 473. ALPO/BAA weight=2.
Eratosthenes 1976 Sep 08 UTC 04:29 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector 45-225x, S=5-4, T=5) "Psuedo-shadow X3 was present but X disappeared from wall(same intensity?) which was rated 4 deg. Disappearance of X so unexpected that he examined inner S wall very carefully & was certain it was free from psuedo-shad. Had vanished within 24h. Other pseudo-shadows showed no change. X reappeared next nite. (X must have been 4deg; &this is much higher than any other meas.). Variability of wall shadows may habe been what Pickering saw, suggests Bartlett."

On 2009 Sep 03 at UT23:15-23:17 B.Gibbs took some hand held digital SLR images of the Moon (Sky conditions clear). Four images were taken at: 23:14:53, 23:15:59, 23:16:05 and 23:17:23 (uncertainty +/-15 sec offset from actual UT). These showed some apparent variation in the brightness of Aristarchus. However there are ways toexplain this through image motion blur when the images were taken. However we cannot be absoultely sure. The ALPO/BAA weight=1.

On 2002 mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor, x120 - no cloud, slight haze, no wind, seeing good) noticed during first part of observing period that Aristarchus was getting steadily brighter, very much brighter than Proclus. This continued until 02:36UT when it dimmed suddenly over a period of about a minute or so. No colour effects seen. ALPO/BAA weight=2. Just as an after thought - was it Aristarchus that was varying, or Proclus?
Proclus 2002 Mar 29 UT 05:27-05:36 Observed by Darling (Sun Praire, WI, USA, 12.5" f/5 Newtonian, +Rotating polaroid visual densitometer) "Observations made following telephone alert call about Brook's report. Aristarchus, Proclus and Censorinus monitored for brightness variations from 04:41-05:37UT. Apart form a change in transparency due to cirrus cloud at 05:11-05:18, there were significant dimmings of the brightnesses of Proclus at 05:27. Aristarchus remained constant - this suggested that Clive Brook's earlier report was not a TLP in Aristarchus, but possibly in Proclus which he was using as a comparison" ALPO Lunar Section Report. ALPO/BAA weight=3.

On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 6" reflector, Seing = 6/10) noticed blue on the north east corner of Aristarchus and an orange glow on the south east wall. They detected no movement or change in brightness. The observer used both eyes, to make sure it was not an eye defect, and three filters: red Wratten 25, blue Wratten 82 and Violet Wratten 47. Porter found that the colours faded for a duration of 5 minutes and then returned. Their right eye gave a good view and using their left eye they suspected that it was 0.5 steps brighter than the remainder of the crater. The suspected colour remained visible, even under moments of good seeing conditions. The colour eventually faded over time and was eventually gone. Porter reportd seein gcolour here on the following night. Apparently other bright spots showed no colour. Fitton suggests that the filters used confirm that the south east wass was definitely red in colour. The Cameron 2006 catalog ID=37 and the weight=0. ALPO/BAA weight=1.
Aristarchus 1973 Nov 10 UTC 20:00? Observed by Coates (England, 8" reflector x200, Moon at gigh altitude above horizon). "Attracted to crater because of an orange hue extending towards Herod.

Aristarchus was not normal, but all the following features were: Mare Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than Tycho when normal. Estimated variation was 25%. However the Moon was low and the Moon was yellow. Despite this the observer decided that the effect was real. Cameron 2006 extension catalog ID=32 and weight=2. ALPO/BAA weight=1.
On 1992 Jul 16 at UT 03:32-09:31 D. Louderback (South Bend, WA, USA, 3" refractor, x134) detected yellow on the southern rim of Aristarchus, and the colour looked "darker" through a yellow filter and the region was "duller" than normal. The region was 1 intesnsity step brighter on the 2nd measurement, "on all points in it". The comet tail-like ray had 3 sections and was "mottled" in appearance. Finally the Cobra Head region had possible variations in brightness. The cameron 2006 catalog ID=451 and the weight=3. The ALPO/BAA weight=2.

On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) noticed a lack of detail in the Cape Agarum area - he would normally have expected to have seen some craterlets. However he would not rate this observation much because the seeing was only III and he does not think that it was an obscuration. However just in case he wanted to record this report in the archives. ALPO/BAA weight=1.
Proclus 1973 Nov 11 UT 20:40-23:05 Observed by Savill (Cambridge, England, 12" refractor, x100?), Young (Yorks, England), Pedler (Bristol, England, 6" reflector?), Livesey (Scotland).

At 2104h in 12-in refr. at 260x the lower spot seemed distinctly enlarged & vaporous. Decided it was due to poor seeing. Later the 2 spots were better defined & separated but lower moved away fr. larger one & they seemed more separated than earlier. Obs. ended at 2305h when they decided it was not an LTP. but was 2 craters instead of humps. There were neg. repts. from others at the same time. (there are no craters in Proclus)."

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 or club. (6) Finally this desription will be updated a day or two after the planned impact.
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.
On 1973 Oct 17 at Ut 11:30 Androsan (Edmonton, Canada, 6" reflector, x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place of ring's appearance on the dark limb. The observers attributed it to Saturn and its rings. Cameron speculates that it might be due to gas or dust at the lunar surface.

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.

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.
On 1878 Oct 18 at UT 21:00? Gaudibert (France?, 4" refractor) observed Webb's white spot on SW border of Wargentin that had been brilliant the previous night, had completely vanished tonight. The Cameron 1978 catalog ID=204 and the weight=4. The ALPO/BAA weight=3.
