2025-Aug-01 UT 19:59-22:23 Ill=53% Montes_Caucasus

     Monte Caucasus: "shadow face" silhouette Clair-Obscur effect. 
     Clair-Obscur effects have no scientific importance just tricks 
     of the light that make us think we see something like 
     a letter of the alphabet or a shape or face. Clair-Obscur 
     effects are scientifically useless to observe. However, if 
     you want to be thrilled, or obtain an image to impress someone 
     then give them a go. This effect on the southern end of Montes 
     Caucuses looks like the side silhouette of a cartoon human face. 
     We are still slightly undertain about the precise colongitude 
     range, so if you do not see the face, try again later. If you 
     do observe, or image this, by all means send your observation 
     into ALPO or the BAA, but we probably won't publish, but will 
     nevertheless retain in our archives, just in case features 
     elsewhere in the image are of interest to future researchers.
     Note that we have some uncertainty in the colongitude range 
     - so if you don't see it, please tells us the date and UT so 
     we can make some improvements in the predictions.


2025-Aug-01 UT 20:29-22:35 Ill=54% Earthshine: sporadic meteors

     These can only be observed using low-light level cameras running at 25 frames per sec,
     or faster, and capable of recording 9th or 10th magnitude stars in real time.
     Dates/UTs of observing runs, or detections of impacts, should be emailed to:

2025-Aug-03 UT 23:32-00:10 Ill=72% Montes_Jura

     "Jewelled Handle": in Montes Jura - this is a Clair-Obscur effect. Its
     an illuminated arc. Clair-Obscur have no scientific importance and are 
     just tricks of the light that make us think we see something like a 
     letter of the alphabet or a shape or face. Clair-Obscur effects are 
     scientifically pointless to observe. However, if you want to be 
     thrilled, or obtain an image to impress someone then give them a go. 
     If you do observe, or image this, by all means send your observation 
     into ALPO or the BAA, but we probably won't publish, but will 
     nevertheless retain in our archives, just in case features elsewhere 
     in the image are of interest to future researchers.


2025-Aug-05 UT 00:19-00:56 Ill=81% Promontorium_Heraclides

     Cassini's Moon Maiden at Promontorium Heraclides - this is a Clair-Obscur effect. 
     Clair-Obscur have no scientific importance and are just tricks of the 
     light that make us think we see something like a letter of the alphabet 
     or a shape or face. Clair-Obscur effects are scientifically pointless

     future researchers.


2025-Aug-07 UT 21:24-22:22 Ill=98% Plato

     BAA Request: Two observers have reported colour on the rim 
     around this colongitude, once in 1938, and again in 2013. Please 
     take a look and report what you see, and where on the rim. 
     Please send any high resolution images, detailed sketches, or 
     visual descriptions to: a t c @ a b e r . a c. u k .


2025-Aug-10 UT 22:16-00:13 Ill=97% Tycho

     BAA Request: Tycho. We are trying to replicate, using 
     modern day images, a sketch in Plate X in BAA The Moon 
     from published: 1950 Jun Vol 1, No. 1. It is for a sketch made 
     by H.P. Wilkins from 1949 Jun 05. The original sketch was 
     made with an 12" telescope. Please send any images to: 
     a t c @ a b e r . a c. u k .


2025-Aug-11 UT 03:47-05:21 Ill=96% Aristarchus

     BAA Request: Do the appearance of the bands on the crater rim 
     vary (blur) in appearance over time? Compare them to bands in 
     other craters e.g. Herodotus, Kepler, Copernicus. If you do 
     see any variations in sharpness, see how it relates to 
     atmospheric seeing condtions. All images or sketches should 
     be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Aug-11 UT 23:28-05:54 Ill=91% Cyrillus

     BAA Request: Cyrillus. There is a small white craterlet just 
     north of the three central peaks. We are interested to receive 
     high resolution images of this in order to find out at what 
     selenographic colongitude, in the lunar evening, that it loses 
     it's white spot appearence. Please use scopes largher than 6 
     inches in diameter. 
     Please email these to: a t c @ a b e r . a c . u k

2025-Aug-17 UT 01:59-03:44 Ill=40% Plato

     BAA Request: Its around this Co-Longitude that some observers 
     have reported seeing an Ashen Light effect on the shadowed floor 
     of Plato, caused by scattered light off of an illuminated peak 
     on the rim. Please have a go either visually, or with long 
     exposure time lapse imagery to see if you can pick up the 
     development of this weak illumination effect on the floor. 
     Please send any sketches or images to: 
     a t c @ a b e r . a c. u k .

2025-Aug-26 UT 19:46-20:09 Ill=12% Picard

     BAA Request: On 2013 Feb 17 UAI observer: Giuseppe Macalli 
     observed visually an orange cloud form just to the west of 
     Picard crater, and then dissappear. The effect lasted about 1 
     minute. Obviously we are not likely to see whatever this was 
     (?) again under similar illumination, but just for the record 
     it would be useful to have a high resolution monochrome or 
     colour image of this area, at the requested observing 
     time.N.B. an image in the 2018 Jun LSC suggests that the date 
     given of 2013 Feb 17 may have been Feb 18? Please send any 
     high resolution images to: a t c @ a b e r . a c. u k .

2025-Aug-30 UT 19:58-21:55 Ill=46% Werner

     Werner: an "X" on the Moon - this is a Clair-Obscur effect. 
     Clair-Obscur have no scientific importance and are just tricks of the 
     light that make us think we see something like a letter of the alphabet 
     or a shape or face. Clair-Obscur effects are scientifically pointless 
     to observe. However, if you want to be thrilled, or obtain an image to 
     impress someone then give them a go. If you do observe, or image this, 
     by all means send your observation into ALPO or the BAA, but we 
     probably won't publish, but will nevertheless retain in our archives, 
     just in case features elsewhere in the image are of interest to 
     future researchers.

2025-Aug-31 UT 19:35-20:20 Ill=55% Apollo_15

     Apollo 15: This is what the lunar surface would have looked like 
     when Apollo 15 touched down on the Moon. Aim for the area 
     of Rima Hadley. The illumination and the shadows are
     exactly the same. There is no scientific value in imaging 
     this, but from the nostalgic point of view it might be interesting 
     to observe. Feel free to send your observation in to the BAA or 
     ALPO and we will put it in our archives, but as we have 
     a lot of these images already, we may not publish it, unless it is 
     exceptionally high in resolution. Minimum diameter scope to use 
     would be 20cm, but larger apertures are preferred: 


2025-Aug-31 UT 21:19-21:54 Ill=56% Plato

     BAA Request: It has been noticed that a bright carterlet can 
     appear very suddenly on the floor of Plato in between needle 
     like shadows, during local lunar sunrise. This happens in the 
     space of just a minute or so, and can look really quite dramatic.
     This effect was first spotted by Brian Halls on 2014 Oct 31 
     Please send any high resolution images, detailed scetches, or 
     visual descriptions to: a t c @ a b e r . a c. u k .
