2017-May-01 UT 21:08-22:09 Ill=36% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teighmouth, UK, 10.5" 
     reflector, x180) found, using a Moon Blink device, evidence of colour 
     on the flor patches of Fracastorius crater, brighter in blue than in 
     red. Also the floor to center varied in brightness in blue and in red. 
     Peters observed in white light and found the south east-south wall had 
     a slight orange cast and when a Moon blink was used it was less bright 
     in blue than in red light. M. Cook found spurious colour on the south 
     rim and also on Mons Pico. There was a colour blink reaction on the 
     southeast floor of Fracastorius - this was both faint and blurred and 
     not seen in white light. A.C Cook detected the permanent blink in the 
     south east floor of the crater at 21:47 and a fainter one in the north 
     west (marginally brighter in red than in blue). J.D. Cook found no 
     colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong 
     colour reaction with the Moon Blink device - brighter in red than in 
     blue and detected a pink colour visually on the south east wall 22:10-
     22:45 (this did not give a blink effect though). Cameron 2006 catalog 
     ID=88 and weight=4. ALPO/BAA weight=2.


2017-May-01 UT 21:08-21:24 Ill=36% Grimaldi observed by Price_M on 1980-4-20

     On 1980 Apr 20 at UT20:27 M.Price (Camberley, UK) saw a flash in the 
     Grimaldi-Aristarchus area. Cameron 2006 catalog TLP ID=88 and weight=4. 
     ALPO/BAA weight=2.


2017-May-01 UT 21:08-22:35 Ill=36% Petavius observed by Blair_G on 1980-4-20

     On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used 
     an 8" reflector and seeing=III) saw three patches in Petavius and they 
     could still be seen 7 minutes later. At 21:50UT he used a filter and 
     found the "northern one was brighter in blue, the southern one was 
     brighter in red and the central one was the same shad ein both 
     filters." Cameron comments that the central patch was a permananent 
     one. She then goes onto say that the crater is described as having dark 
     patches that are opposite to what one would expect from Fitton's theory 
     applied to dark features. Cameron 2006 extension catalog ID=88 and 
     weight=4. ALPO/BAA weight=3. 


2017-May-02 UT 00:08-00:19 Ill=37% Aristarchus observed by Cook_JD on 1981-3-11

     A faint white pinpoint flash seen and also in the same position
     a whitish glow around the crater. No futher flashes seen after the
     first one. From UT2117-2130 the glow was still visible but faded
     making it more difficult to locate. When Foley observed he found 
     Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
     and several other features being visible. Both observers used
     12" reflectors. Cameron's 2006 catalog Extension ID=124 and 
     weight=0. ALPO/BAA weight=3. 


2017-May-01 UT 21:38-00:21 Ill=37% Earthshine: sporadic meteors

2017-May-02 UT 21:07-21:29 Ill=48% Torricelli_B observed by Braga_R on 2001-4-29

     On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any 
     filter, the brightness of the east wall of Torricelli B was halfway 
     Torricelli C (faintest) and Moltke (brightest). By insering a Wratten 
     25 red filter though, the crater was slightly more evident. However 
     using a blue Wratten 39A filter, the crater vanished completely, whilst 
     Toricelli C remained. The ALPO/BAA weight=3. 


2017-May-02 UT 22:13-01:08 Ill=48% Messier observed by Klein_HJ on 1878-11-1 *

     Messier 1878 Nov 01 UT 20:00? Observed by Kleis (Cologne, Germany, 6" 
     refractor?) "Shaped like a half moon with E. edge missing. Appeared 
     diffuse. Messier A was sharp & completely defined. Was sure there was 
     fog there. Next day same appear. Shadow was diffused before noon, Mess. 
     A is more yellow after noon, greener near Mess. A noon, both are same 
     color." NASA catalog weight=4. NASA catalog ID #206.
     ALPO/BAA weight=3.


2017-May-02 UT 22:51-23:53 Ill=48% Aristarchus observed by Butler_FC on 1981-3-12

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's 
     2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA 
     weight=2.


2017-May-03 UT 00:21-01:25 Ill=48% Mont_Blanc observed by Schroter on 1789-9-26

     On 1789 Sep 26 at UT 03:30 Schroter (Lillienthal, Germany) observed 
     close beneath Mons Blanc at the west foot, in the dark, a small 5th 
     magnitude, speck of light. Its round shadow was sometimes black, 
     sometimes grey. Cameron suspects that this is the same as her TLP 
     report No. 50. the Cameron 1978 catalog ID=62 and weight=4. The 
     ALPO/BAA weight=3.


2017-May-03 UT 01:06-01:25 Ill=49% Aristarchus observed by Schroter on 1789-9-26

     On 1789 Sep 26 at UT04:25? Schroter (Lillienthal, Germany) 
     noted a bright point 26" north of Aristarchus crater. Note 
     that the year might have been 1788? The Cameron 1978 catalog 
     ID=50 and the weight=3. The ALPO/BAA weight=3.


2017-May-03 UT 01:06-01:25 Ill=49% Plato observed by Schroter on 1789-9-26

     On 1789 Sep 29 at UT04:25? Schroter (Lillienthal, Germany) noted 
     1'18.5" south east of plato was a whitish bright spot shining somewhat 
     hazily, 4-5"in diameter and at 5th magnitude. He never saw this again. 
     The spot became conspicuous at times and then disappeared. There was 
     nothing else similar in Earthshine. Note that the year might have been 
     1788? The Cameron 1978 catalog ID=50 and the weight=3. The ALPO/BAA 
     weight=3.


2017-May-03 UT 01:16-01:25 Ill=49% Mare_Crisium observed by Schroter on 1789-9-26

     Schroter, from Lillenthal in Gemany, in 1789 (possibly it was 1788) Sep 
     26 UT 04:30 saw a small nebulous bright spot on the northern edge of 
     Mare Crisium. Cameron 1978 catalog ID=50 and weight=3. ALPO/BAA 
     weight=2.


2017-May-02 UT 21:37-01:27 Ill=49% Earthshine: sporadic meteors

2017-May-03 UT 21:06-21:43 Ill=58% Alphonsus observed by Lenham_AP on 1952-11-24

     Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
     inch efractor x120) noted that the usual dark spots were not 
     visible, but floor ridges and craterlets were surperbly seen. 
     This may not be a TLP but has been given a TLP category as it 
     is a curious appearance and needs to be verified on a repeat 
     repeat illumination apeparance. ALPO/BAA weight=1.


2017-May-03 UT 21:06-21:26 Ill=58% SE_Limb observed by Rohslberger_R on 1980-4-22

     On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West 
     Germany, 8" reflector, x170 25mm occular used, 300mm focal length?) 
     took some photographs using projection. One of these recorded an 
     apparent "ejecta curtain". Cameron considered lens flare, but the other 
     photographs did not show this. If real then the plume was at a height 
     of ~40km and the ray was ~130km. Cameron concludes that this was an 
     impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The 
     ALPO/BAA weight=3.


2017-May-03 UT 21:06-23:25 Ill=58% W_Limb observed by Miles_H on 1987-1-7 *

     On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright 
     patches were seen in Earthshine at clock positions of 4 (this patch was 
     defined by the dark limb and the brightness faded inwards to the disk, 
     over a short distance. "Centred at 60 deg along the limb from the north 
     - a sketch showed approximately 10-15 deg along it") and 5:30 (this 
     second patch was smaller and not so bright as the first patch - it was 
     west of the north pole. P. Foley (Kent, UK) also detcted the patches 
     and said that one was not far from the sunrise terminator. 
     The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a 
     weight of 2. The ALPO/BAA weight=2.


2017-May-03 UT 21:59-23:50 Ill=59% Alphonsus observed by Hopp on 1972-9-15

     Alphonsus 1972 Sep 15 UTC 18:48-18:56 Observed by Hopp (13.25E, 52.5N, 
     75mm refractor) "Diffuse white to blue area within the crater - not 
     sure" T=4, S=4. Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol 30, 
     pp53-61.


2017-May-03 UT 22:48-00:27 Ill=59% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the 
     "Observations and Comments" column in the December, 1953 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.


2017-May-03 UT 23:08-02:04 Ill=59% Messier observed by Klein_HJ on 1878-11-2 *

     Messier 1878 Nov 02 UT 20:00? Observed by Kleis (Cologne, Germany, 6" 
     refractor?) "Shaped like a half moon with E. edge missing. Appeared 
     diffuse. Messier A was sharp & completely defined. Was sure there was 
     fog there. Next day same appear. Shadow was diffused before noon, Mess. 
     A is more yellow after noon, greener near Mess. A noon, both are same 
     color." NASA catalog weight=4 (very high). NASA catalog ID #206.


2017-May-03 UT 23:16-01:12 Ill=59% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.


2017-May-03 UT 23:31-01:28 Ill=59% Dawes observed by Thornton_FH on 1948-2-17

     Dawes 1948 Feb 17 UT  19:30 Observed by Thornton (Northwick, England, 
     18" reflector) "Did not see c.p. saw cleft-like streaks from SW crest 
     to E, shadow." NASA catalog weight=3 (average). NASA catalog ID #501.


2017-May-03 UT 23:41-01:37 Ill=59% Curtis observed by Williams_AS on 1882-8-21

     Williams of the UK, on 1892 Aug 21 at 19:30UT (Moon's age 7.9 days)
     noticed a spot at least half as bright, and as large as Picard, near
     to Picard crater. This observation was reported in the Astronomical
     Register of the Royal Astronomical Society and is not included in the
     Cameron catalogs. It is one of many measurements of the brightness of 
     this spot for different illumination angles and is one of three 
     outlying brightness points spotted on a graph by Willaims. The ALPO/BAA 
     weight=3.


2017-May-03 UT 23:49-00:46 Ill=59% Pickering observed by Collier on 1971-1-4

     Pickering 1971 Jan 04 UTC 20:29-20:37 Observed by Collier (London, 
     England) "Between Saunder and Rhaeticus, apparently coming from Pick. 
     After 2027h it dimished with extraordinary swiftness, like a light goes 
     out. (experienced observer)" NASA catalog weight=?. NASA catalog ID #
     1281. Note that this crater was previously called E.C. Pickering before 
     the IAU renamed some craters.


2017-May-04 UT 00:56-02:31 Ill=59% Archimedes observed by no on 1967-1-18

     Archimedes 1967 Jan 18/19 UT 23:00?-01:00? Observed by Delano (New 
     Bedford?. Massachussetts, USA, 12.5" ? reflector) and by Corralitos 
     Observatory (Organ Pass, NM, USA, 24" reflector + Moonblink) "Saw an 
     obscuration or unusual appearance on floor. Not confirmed by Corralitos 
     MB., but their rep't says Aristarchus)" NASA catalog weight=4 (high). 
     NASA catalog ID #1009. ALPO/BAA weight=1.

     North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed 
     by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black 
     curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1

2017-May-04 UT 21:05-21:20 Ill=69% Pallas observed by Stuart_L on 1953-11-15

     Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA) 
     "Saw and photographed a bright spot on term. between these two 
     craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog 
     ID #559. ALPO/BAA weight=5.


2017-May-04 UT 21:05-22:14 Ill=69% Aristarchus observed by Loocks on 1969-11-18

     On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector) 
     observed a flash of light of magnitude 12. Cameron speculates a meteor 
     and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and 
     weight=1. The ALPO/BAA weight=1.


2017-May-04 UT 21:05-21:25 Ill=69% Eratosthenes observed by Galdies_C on 2012-8-25

     On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C. 
     Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4 
     Registaxed images were produced covering 19:45, 19:48, 19:49, 
     and 19:51. All but the first image, once first order spurious 
     colour had been removed, showed orange on the shaded terraces on 
     the western illuminated rim (similar to what Paul Abel and 
     others saw in 2009, albeit just confined to the NW rim), and the 
     interior floor shadow was slightly smaller in red light. However 
     orange colour was also seen on the eastern side of mountains to 
     the south of the crater, which infers that the spurios colour 
     removal did not fully acomplish its main goal. The effects were 
     not caused by the registax software as the orange colour is 
     visible on individual images. Although probably the colour is 
     not lunar in orgin, its explanation is not fully explaianed, 
     therfore an ALPO/BAA weight of 1 is used for now.


2017-May-04 UT 21:09-23:01 Ill=69% Eratosthenes observed by Hill_H on 1947-1-30

     Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main 
     peak of massive central mountain group appeared to be in a shadowless 
     having regard to it's claimed height of 6,600 ft. The whole of the 
     floor to the west should have still been in darkness. Instead 
     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."


2017-May-04 UT 22:26-00:22 Ill=69% Aristarchus observed by Tempel on 1886-6-10

     On 1886 Jun 10 at UT 21:00 (estimated) Tempel of Germany, saw a star-
     like light (Cameron comments that the reference in the Middlehurst 
     catalog is wrong). Cameron 1978 catalog ID= and weight=4. ALPO/BAA 
     weight=3.


2017-May-05 UT 00:00-01:57 Ill=69% Proclus observed by Cook_MC on 1981-5-12

     On 1981 May 12 UT 22:00? M.C. Cook (Frimley, UK and using a 12" 
     reflector), noticed that Censorinus was very bright, fuzzy and 
     occasionally brighter than Proclus. However both Foley (Kent, UK) and 
     Amery (Reading, UK) using a C.E.D. found that Proclus was brighter than 
     Censorinus as it had been during April and May 1981. However Chapman 
     obtained the reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=2.


2017-May-05 UT 00:02-01:57 Ill=69% Proclus observed by Darling_D on 1989-12-6

     On 1989 Dec 06 at 23:09-23:34UT D. Darling of Sun Praire, WI, USA (3" 
     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.


2017-May-05 UT 00:45-02:42 Ill=70% Censorinus observed by Cook_MC on 1981-5-12

     On 1981 May 12 UT 22:45-2325 M.C. Cook (Frimley, UK and using

     fuzzy and occasionally brighter than Proclus. However both 
     Foley (Kent, UK) and Amery (Reading, UK) using a C.E.D. found 
     that Proclus was brighter than Censorinus as it had been

2017-May-05 UT 02:40-03:34 Ill=70% Plato observed by Carle on 1952-11-26

     In 1952 Nov 26 at UT 01:00? Carle (USa, 8" reflector, x700, seeing = 
     poor) observed the following in Plato: "Sketch shows 8 spots -- 5 
     craters showed interior shad., 1 completely filled, but no others seen 
     despite several hrs. of study. Spots that should have been seen were 
     missing. poor seeing converts floor into shimmering shapeless blob. Has 
     observed it under good seeing & seen nothing on fl. as others have 
     noted". The Cameron 1978 catalog ID=555 and weight=3. The ALPO/BAA

2017-May-05 UT 03:10-03:34 Ill=70% Lambert observed by Jones on 1902-8-13

     On 1902 Aug 13 at UT 00:50 Jones (Philadelphia, Penn, USA, 6" 
     reflector, x250) observed a brilliant star-like point near Lambert 
     (21W, 25N) on the dark side of the terminator. It was a magnitude 3-4 
     round spurious disk and had an interference or diffraction ring. 
     Resolved into a very brilliant spot as the terminator neared it. 
     Cameron says that thios was too far from the terminator to be a sunlit 
     peak? The report is given as Aug 12 in Middlehursts's catalog. The 
     Cameron 1978 catalog ID=312 and weight=1. The ALPO/BAA weight=1.


2017-May-05 UT 03:14-03:34 Ill=70% Montes_Carpatus observed by McCorkle on 1955-8-27

     On 1955 Aug 27 at UT 01:51 McCorkle (Memphis, Tennessee, USA, 6.5" 
     reflector, x200) observed a 2nd magnitude bright flare on the dark side 
     of the Moon. This remained steady, fading slightly before abruptly 
     disappearing. Cameron suggests that this might have been a meteor. The

2017-May-06 UT 02:06-04:03 Ill=79% Curtis observed by Williams_AS on 1882-8-23

     Williams of the UK, on 1892 Aug 23 at Moon's age 10.0 days, noticed a 
     spot now rated at +1.5 (in brightness) that had been seen on the 21st 
     Aug, near Picard. Williams comments that this is the only obsewrvation 
     that departs "much" from the curve of diurnal brightness. The spot was 
     descibed as "nearly as large as Picard and nearly half as bright. This 
     observation was reported in the Astronomical Register of the Royal 
     Astronomical Society and is not included in the Cameron catalogs. It is 
     one of many measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness points 
     spotted on a graph by Willaims. The ALPO/BAA weight=3.

     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)

2017-May-06 UT 03:16-04:36 Ill=79% 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.

     using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on 
     the western wall of Eimmart (sketch supplied) have an unusual 
     brightening and shade. Variations occurred over 2-3 minute intervals. 
     Louderback commented that the spot looked like a flare with its apex 
     located at the crater wall and there was some blurring effect on the 
     spot - it decreased in size during the phenomenon. Seeing worsened 
     later. Apparently on the 18th and 19th of April everything was back to 
     normal. Cameron comments that there is no bright spot on the Moon at 
     this location. Lunar Orbiter IV plates 192-3.2 shows evening

     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

     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     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 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

     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.

2017-May-11 UT 04:50-06:37 Ill=100% 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. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended
     catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2.

     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.


2017-May-11 UT 05:53-07:50 Ill=100% Proclus observed by Brook_C on 2002-3-29

     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?


2017-May-11 UT 06:16-08:13 Ill=100% Eimmart observed by Louderback_D on 1980-4-30

     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:
     Personal communication from Louderback to Cameron on 1980 Jul 16th.
     The Cameron 2006 catalog extension ID of this TLP was 93 and the 
     weight was 4. ALPO/BAA weight=3.

     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.

2017-May-11 UT 23:42-01:11 Ill=99% Torricelli_B observed by Cook_AC on 1985-12-28

     CCD images taken through Wratten 25 (red+near IR) and 87 
     (near IR only) filters. Between 00:02 and 00:25UT there
     was some slight evidence that a fade may have taken place
     however careful analysis by Cook casts doubt on this.
     Probably it was more related to a degradation in image 
     quality due to seeing than a true TLP. An ALPO/BAA
     weight of 1 has been assigned.

     On 1957 Jul 31 UT 02:24 C. Johnson (4" reflector, x91, seeing 10/10) 
     observed a slight ring of light reaching around the north limb of the 
     Moon. The ring was only just brighter than Earthshine and about 1600km 
     long. The Moon's age was 3.9 days. The reference for this comes from;

     reflector and 3" refractor, seeing II-III, conditions very good) noted 
     that the inside of Aristarchus had a star-like point contained within a 
     diffuse blue-green hue coloured glow. There were also intermittent 
     flashes visible during short irregular periods using a Wratten 44a 
     (blue-green filter)but were difficult to see trhough a Wratten 25 (red) 
     filter. The Moon was at a low altitude and the observation ceased at 
     22:25UT. P.W. Foley (Hent, UK, seeing II) observed flashes in 
     Aristarchus and occasional star-like points - he also observed the area 
     to be in a bluish translucent glow extending for about 40 miles all 
     around the crater. In order to check on the visibility of Earthshine, a 
     region of highland, near Grimaldi was checked and found to be 0.2 
     bright with no variations. However Aristarchus itself varied from a CED 
     freading of 0.6 to unmeasurable. Foley observed from 20:10-22:30UT. P. 
     Madej (Huddersfield, UK, 77m refractor, seeing I-III) observed at 
     22:17UT and saw the crater as a "ghostlike gossamer light". Cook, Moore

     like a "gigantic nuclear bomb explosion "which expanded (to 1/8th the 
     diameter of mare Crisium) and then reduced in size. The flare fickered 
     at a rate of 1/10s. apparently the edge of this TLP looked rough, 
     almost like emittyed debris. The TLP was fixed in position on the Moon.

2017-May-30 UT 20:47-22:05 Ill=32% Aristarchus observed by Nottingham_University on 2006-11-25

     CCD images were captured in white light that seemed to show that
     the relative brightness between Aristarchus or Pytheas differed
     considerably to what they were to be one night later on 2008 Nov 26.
     Either Aristarchus was brighter on the 25th or Pytheas was darker.
     Which feature, and which night, the abnormality occurred on is 
     uncertain. One possible explanation might be a brightness
     gradient from glare from the sunlit side affecting the image contrast
     quality of the CCD images for relative photometric measurements.
     This TLP is being assigned a weight of 3 for now.

2017-May-30 UT 22:32-23:26 Ill=33% Aristarchus observed by Joulia on 1931-2-22

     On 1931 Feb 22 at UT 20:30 Joulia (Castelnaudary, Aude, France?) 
     observed in the Aristarchus region: "Reddish-yellow glimmer of light, 
     very variable with nearly complete extinction. (similar to Herschel's 
     1787 & Tempel's 6/10/1866 obs.)". The Cameron 1978 atalog ID=399 and

     On 1978 Dec 25 at UT 02:00 Taboada (Mexico) noticed that Aristarchus 
     appeared to brighten in the dark though less intensely than Copernicus 
     and Kepler (Cameron comments: šlso brightening?). Alerted for tidal 
     predictions by Middlehurst - Apollo 8 watch. The Cameron 1978 catalog

     On 1979 Jun 30 at UT0246-0319 D. & D. Darling (Sun Praire, WL, USA, 
     12.5" reflector, 80x and 150x, S=5/10). A weak blue glow seen in the 
     Aristarchus region. It was fainter than that in May 1979 but was 
     relatively easier to see. There was one "streamer" going south and 
     another to the south west, and then smaller ones within the crater. 
     These streamers started to fade from view at 03:04UT and the blow glow 
     changed to a blow spot and Aristarchus became normal by 03:19 UT.

2017-May-31 UT 00:15-00:18 Ill=33% Aristarchus observed by Fallows on 1821-11-29

     Observer: Fallows Observing site: Cape Town, South Africa. Cameron 1978 
     catalog describes the event as: Bright star-like point.
     A more detailed account is as follows: Early in the year 1821 -- and a 
     light shone out on the moon -- a bright point of light in the lunar 
     crater Aristarchus, which was in the dark at the time. It was seen, 
     upon the 4th and the 7th of February, by Capt. Kater (An. Reg., 1821-
     689); and upon the 5th by Dr. Olbers (Mems. R.A.S., 1-159).(25) It was 
     a light like a star, and was seen again, May 4th and 6th, by the Rev. 
     M. Ward and by Francis Bailey (Mems. R.A.S., 1-159).(26) At Cape Town, 
     nights of Nov. 28th and 29th, 1821, again a star-like light was seen 
     upon the moon (Phil. Trans., 112-237).(27).Cameron 1978 catalog ID=92

2017-May-31 UT 21:12-23:09 Ill=43% Eudoxus observed by Jean on 1988-11-15

     On 1988 Nov 15 at 10:07-10:40 UT P. Jean (Outremont, Quebec, Canada, 
     4" refractor?) saw to the SE of Eudocus (18E, ~43N) a luminescent area 
     just over on the night side of the terminator - it was cone shapes and 
     coppery in colour. Cameron comments that maybe it was a very low sun 
     angle effect and she has seen something similar, but on the bright side 
     of the terminator. Jean then goes onto comment that at 10:25UT a very 
     dark line was seen south of the cone i.e. east of the terminator. A 
     sketch was provided and P.Foley commented that the cone did not 
     correspond to any terrain. Cameron 2006 Catalog Extension ID=339 and

2017-May-31 UT 23:01-23:59 Ill=44% Proclus observed by Gray_R on 2003-2-8

     Proclus 2003 February 8,2003 UTC 02:09-03:07 Observed by Gray 
     (Winnemucca, NV, USA, 152mm F9 refractor Seeing 6-7, Transparency 6 
     305x) "Blinked Proclus with Wratten Red 25 and Blue 38A filters. 
     Features seen through the red filter were basically seen with the same 
     degree of clarity as in white light, in the case of sunlit walls, maybe 
     a little bit better in the red. With the Blue 38A filter only the 
     brightest part of the crater walls (north end) was visible-the rest of 
     Proclus was dark shadow. At 3:07UT I compared the brightest parts of 
     Proclus with Censorinus and Dionysius. The brightest parts of Proclus 
     and Dionysius were comparable. Censorinus was much less bright than 
     either of the above craters-the halo and crater were much faded over 
     its usual brilliant appearance. Both Censorinus and Censorinus A
     were visible as distinct craters at 114x. The black shadow covering the 
     east 40% of Proclus last night had broken up into three patches 
     separated from each other by lighter bands. These were confined to
     the east crater wall. Only the central patch was black, the other two 
     were considerably lighter. Running along the southwest edge of the 
     crater floor of the crater floor appeared to be a hill to the north
     of which was a less elevated plateau. As the observing period 
     progressed part of the brilliantly illuminated north crater wall 
     developed a darker area which gradually became more prominent. As
     the sun is getting higher I would expect shadows and dark areas to 
     diminish-what was happening here is unknown. However, this is not an 
     unusual event for this part of Proclus". The ALPO/BAA weight=2.
