2018-May-01 UT 02:39-03:45 Ill=99% Aristarchus observed by Moore_P on 1977-7-1 *

     P Moore, Selsey, Sussex, UK, used a 5" x250 scope and between
     23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
     Aristarchus. The south wall of the crater was reddish, extending 
     down to the outer south east wall (IAU). However seeing was no 
     better than III-IV and he was 99% sure that the colour was 
     spurious. His report was submitted only in case any other 
     observers reported something similar. ALPO/BAA weight=1.


2018-May-01 UT 03:55-05:51 Ill=98% Aristarchus observed by Bartlett on 1955-10-2

     On 1955 Oct 02 at UT 05:30-05:55 Bartlett (Baltimore, MD, USA, 3.5" 
     reflector, x100, S=7, T=5) observed the following in Aristarchus 
     crater: "Viol. gl. on E, NE rim, over EWBS resembled a viol. mist. 
     Crater itself was hazy, could not get a sharp focus". The Cameron 1978 
     catalog ID=615 and weight=4. The ALPO/BAA weight=2. 


2018-May-01 UT 04:22-06:09 Ill=98% Torricelli_B observed by Mobberley_M on 1985-12-27

     Mobberley noticed that Torricelli B was bright and had an even brighter 
     spot on the inner north wall. The observation was made from UT19:45-
     21:40 using visual and video techniques. There was also a bright region 
     NNE of Toricelli B, that was noticed. Foley examined the video and 
     found that the crater faded in brightness over time and also the bright 
     area to the NNE was not as bright on video as had been seen visually. 
     Foley speculates that because the CCD camera was sesnitive to the near 
     IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and 
     also saw the bright spot on the inner north wall - but saw a blue halo 
     around the crater. Response in blue filter, darkening over whole 
     region. Brightness measures with a crater extinction device (CED) 
     indicated that the crater was 80-85% the brightness of Censorinus. 
     There was a bright area NNE of the region. M. Cook observed 22:10-
     22:16UT (15cm reflector and seeing III-IV) and also saw that the crater 
     was very bright indeed with a spot NNE of the region (same position as 
     28/28 1985 observation) - suspected that the crater might have been 
     brighter than Censorinus, but judgement effected by seeing. In a blue 
     filter the crater dulled leaving the bright spot prominent (but only 
     during a good moment of seeing) - therefore had some suspicion of 
     seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the 
     area, but the seeing was even worse - but did manage a check of the 
     brightness of Torricelli B to Censorinus and now made it one quarter of 
     that of Censorinus and no sign of the crater dimming in the blue as had 
     been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 
     21:15UT (Dec 27) thought that Torricelli B looked normal and saw no 
     colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images 
     through red+IR (Wratten 25) and IR (Wratten 87) but found no colour 
     differences, though there was a very slight hint that a brightness fade 
     may have occurred between those two observing times. Note that this
     report does not have an entry in the Cameron 2006 Extension Catalog.
     The ALPO/BAA weight=4.

2018-May-01 UT 06:02-07:59 Ill=98% Aristarchus observed by Madej_P on 1984-2-17

     On 1984 Feb 17 at 19:45-22:20UT P. Madej noticed colour in Aristarchus 
     and telephoned the BAA Lunar Secton TLP network. Mosely at 21:15UT 
     observed that Aristarchus was both bright and fuzzy - there was some 
     spurios color (red on south and blue on the north) but this was 
     replaced by violet. By 21:30UT (transparency=fair) the centre of the 
     crater was bluish and the west wall creamy white. the north and south 
     walls were brilliant white. By 22:00-22:30 UT the seeing had improved 
     and the crater looked unusual - now the centre was violet and the west 
     wall duller, off-white. By 05:35UT the crater was difficult to define 
     according to Cook - 4 bands could be seen under II seeing and the north 
     rim was fuzzy and less bright than the east wall (this was hazy). P. 
     Moore observed that the crater was normal at 04:00UT. Cameron 2006 
     catalog extension ID=242 and weight=3. ALPO/BAA weight=2.


2018-May-01 UT 06:02-07:59 Ill=98% Reinhold observed by Madej_P on 1984-2-17

     on the northern terraces, at the base of the inner wall in a 
     summit crater on the last of a crater chain or ridge 
     descending from the top to floor". Cameron 2006 catalog

     Proclus 1972 Nov 21 UT 21:30 Observed by Farrant (Cambridge, England, 
     8.5" reflector, x130) "Thickened bright ring remained, but the dark 
     patch had disappeared. (dark patch prob. real temporary phenom. as it

2018-May-01 UT 07:41-09:29 Ill=98% Arago_B observed by Mobberley_M on 1983-1-29 *

     On 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector) 
     noted that Arago B had a slight tinge of violet colour, and was a lot 
     less (bright?) than Torricelli B's blueness. Other craters checked but 
     were not showing any blue colour. The Cameron 2006 catalog ID=198 and 
     weight=5. The ALPO/BAA weight=3. 


2018-May-01 UT 07:41-09:29 Ill=98% Moltke observed by Mobberley_M on 1983-1-29 *

     On 1983 Jan 29 at UT22:09 M. Mobberley (Suffolk, UK), found that Moltke 
     crater was "exceptionally bright". Other craters (apart from Arago B 
     Torricelli B etc) appeared normal. The Cameron 2006 catalog ID=198 and 
     the weight=5. The ALPO/BAA weight=2.


2018-May-01 UT 08:36-09:04 Ill=98% 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.

     12.5" reflector at x300-400 - seeing IV) saw colour in Aristarchus (red 
     on the south east wall and southern "horn" of the crater. He could not 
     detect colour elsewhere, but felt that the effect might have been 
     spurious colour. With the increasing altitude of the Moon the light 
     effect decreased. Moore detected red the next night as well (May 25th)

2018-May-03 UT 07:46-09:36 Ill=89% Torricelli_B observed by Mobberley_M on 1985-12-29

     On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds, 
     Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley 
     examined the tape and noted something that Mobberley had not seen 
     visually. Two scans of Totticelli B had taken place, one at 23:23 and 
     the other at 23:58UT. In the first a brilliant point appeared briefly, 
     on the western rim, positioned at 3o'clock. In the second video 
     sequence this brilliant spot was present continuously and wandered 
     along the rim. It was possible to monitor frequency of turbulence 
     present, this apparent movement did not ppear to conform, although 
     judgement here was extremelydifficult as the feature was at absolute 
     point of resolution, a little better than 0.5 mile. Also considered was 
     the implication of the equipment effect, this did not seem to fit 
     either as other nerby craters in the same configuration, 30% shadow 
     filled with sunlight on exterior of western walls. A point to watch for 
     in future. ALPO/BAA weight=3.

     On 1987 Nov 28 UT at 20:14 (possibly earlier)-20:44 M.Mobberley saw the 
     northern rim of Proclus very bright for first quarter. There were 
     streaks half way up the wall and these seemed to vary in brightness and 
     length in seconds. Seeing was at first suspected but became doubtful 
     over this being a cause. There was also another bright streak that 
     changed brightness over 5 minute intervals (Cameron says that this is 
     not atmospheric) Apparently video was taken and confirms the effects. A 
     sketch was also made. M. Cook detected a blink with coloured filters 
     i.e. being brighter in red light (Also apparently confirmed by 
     Louderback). Estimated the north west wall was x3 brighter than 
     Censorinus. Censorinus itself varied in brightness as measured using 
     CED devices. P. Foley decided that the north was was much brighter than 
     Proclus (beyond the limits of the scale. However both Moore and Mason 
     agreed that the north wall of Proclus was very bright but shimmering 
     around in the bad seeing. They did not see any bright spots either. 
     A.C. Cook (20:18-20:44UT) confirmed that the north wall of Proclus was 
     very bright. Towards the end of the observing period the north wall had 
     faded from this maximum brightness - Cameron suspects that this might 
     have been as a result of an eyepiece misting up. The TLP was also 
     observed by Foley (Maidstone, Kent, UK) and he reported: "Bright spot 
     on north wall, Moon blink reaction". A BAA Lunar Section report with

     On 1987 Nov 28 M. Cook (Frimley, UK) found Censorinus varied in 
     brightness as measured using CED devices. P. Foley decided that the 
     north was was much brighter than Proclus (beyond the limits of the

     inside Hipparchus L crater using averted vision. Cameron in her 2006 
     catalog extension comments that Hipparchus L is a highlands impact 
     crater with a rille on the western ejecta blanket. The crater is the 
     smallest one in a chain that are sequenced to be half the size of the 
     previous crater in the chain. Apparently the largest crater in the 
     chain is Hind with a largely landslide covered floor - although on the

2018-May-24 UT 00:40-01:59 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 
     Cameron 1978 catalog ID=604 and weight=0. The ALPO/BAA weight=1.

2018-May-24 UT 01:06-02:31 Ill=71% Aristarchus observed by Madej_P on 1984-12-31

     Although the crater was on the night side, a small bright spot
     was seen. This was blue, almost UV, and equivalent to a star of
     magnitude 2. It flashed over intervals of about 30 seconds
     and changed in colour from UV to blue. The BAA Lunar Section
     TLP network was alerted. Mobberly and J.Cook did not see much
     although J. Cook may have seen something, but located else where?
     Cameron lists this as a confirmed? observation? The Cameron
     2006 TLP xtension catalog has this TLP with an ID No. of 258
     and a weight of 4. The ALPO/BAA weight is 2.


2018-May-24 UT 01:58-03:51 Ill=71% Plato observed by King_N on 1983-4-21

     On 1983 Apr 21 at UT 21:55-22:05 N. King (Winersh, Berkshire, UK, using 
     a 150cm f/8 reflector, with seeing I and transparency good, little 
     spurious colour, just a little in Plato). Although observing since 
     21:25UT the observer noticed  a cery, just detactable faint green 
     colour just after the dark shade around the inner eastern crater rim. 
     The effect faded and by 22:05UT had completely gone. This report is not 
     in the Cameron 2006 catalog. It is a BAA report. The ALPO/BAA weight=2.

     On 1983 Feb 21 at 20:00UT P.W. Foley (Maidstone, Kent, UK, 12" 
     reflector) noticed a deep steel blue colour inside Toricelli B with a 
     lighter colour about 10-15 miles outside. Foley came to the conclusion 
     that this was too visible for its size. Cameron 2006 Catalog extension

     On 1995 Sep 03 at UR19:40-20:15 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.

     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.

     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.

2018-May-24 UT 05:23-05:32 Ill=72% Copernicus observed by Blair_G on 1980-5-23

     On 1980 May 23 at UT21:14-22:18 G. Blair (Bridge of Weir, 
     Scotland, UK, 216mm reflector, seeing II-IV) found a red tinge 
     along the western wall of Coperncius, perhaps 32km in length. 
     This was invisible in a blue-green Wratten 44a filter, but was 
     unmistakble in a red Wratten 25 filter. Could have been 
     spurious colour - but no other regiosn were affected. The 
     ALPO/BAA weight=2. 


2018-May-24 UT 05:23-05:32 Ill=72% Littrow observed by Petek on 1980-5-23

     On 1980 May 23 at UT 21:14-21:18 Marco Petek (Porto Alegre, 
     Brazil) saw in the region of Littrow and an area of dark mare 
     south west from Littrow to Argaeus, abnormal darkness, and a 
     rapid change of form. He also saw a shadow extending south 
     east from Campanus opposite to the Sun - however Foley thinks 
     this is normal. Cameron 2006 catalog ID=96 and weight=0 or 1. 
     ALPO/BAA weight=1.


2018-May-24 UT 05:37-06:57 Ill=72% Copernicus observed by Horner_E on 2012-9-24 *

     2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury, 
     UK, 15cm reflector) observed a prominent red arc where the 
     sunlit part of the interior wall met the shadow. Sometimes the 
     arc was 1/4 the way around the interior, and sometimes half of 
     the way around. Telescope moved, but the red arc stayed where 
     it was. Eyepieces change, but the effect remained. Other parts 
     of the Moon checked, but no red seen. There were however 
     splashes of green e.g. Longomontanus on the terminator, 
     elsewhere further inland from the termionator, and little 
     splashes of green on Mare Frigoras - but lasting a brief time. 
     The red colour was as strong as a red LED and the green similar 
     to that of the northern lights. The observer's husband was asked 
     to independetly check Copernicus and remarked that he could see 
     a little bit of green at the top and some red near the bottom, 
     along the line of the internal shadow. Although there were 
     checks for red elsewhere on the Moon and none were seen, the 
     Moon was starting to get low and it is typical of spurious 
     colour in a few respects. Therefore the ALPO/BAA weight=1 for 
     safety.


2018-May-25 UT 00:40-00:49 Ill=80% 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.

2018-May-25 UT 00:40-02:00 Ill=80% 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=
     240 and weight=2. ALPO/BAA weight=3.


2018-May-25 UT 00:40-02:00 Ill=80% 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.

     Plato 1982 Jun 02 UT 22:00. Mobberley could not see the 
     central craterlet on the floor of Plato tonight. Foley notes 
     that he could only just see the central craterlet on nights of 
     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All 
     three observers compared the Plato area to other areas for 
     reference. All the above seems normal, apart from the floor
     being brighter in the green filter. Cameron 2006 extension

2018-May-26 UT 01:21-03:13 Ill=88% 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

     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.

     Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
     the floor beneath the north wall, and the area over the north
     wall were indistinct (almost out of focus). Despite looking
     elsewhere in the crater and surrounds, no other blurring
     (obscuration of detail) could be seen, indeed everywhere else
     was sharp and detailed. Foley tried several eyepieces but this
     made no difference. He used a crater extinction device but
     found no variations in brightness. There was a slight
     darkening when he used a red filter in the Moon Blink device.
     The obscuration effect weakened between UT20:56 and 21:10,
     was difficult to see at 21:13 and had finished by 00:15.
     Patrick Moore (12" reflector, Dublin, Ireland) saw nothing

     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.

2018-May-30 UT 03:33-03:55 Ill=100% Herodotus observed by Kilburn_K on 1971-12-2

     Herodotus 1971 Dec 02 UT 20:40 Observed by Kilburn 
     (Manchester, UK, 8" refractor, x130, Transparency very good 
     with a thin mist, seeing excellent, x130). Bright point 
     (considerably brighter than its surroundings) was seen on the 
     SE of the illuminated floor of Herodotus in white light. It 
     was quite close to the crater rim. The spot had no colour.

2018-May-30 UT 03:33-04:54 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.


2018-May-30 UT 03:33-04:31 Ill=100% Aristarchus observed by Brook_C on 2002-3-29

     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.


2018-May-30 UT 03:33-04:31 Ill=100% Proclus observed by Brook_C on 2002-3-29

     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

     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.
