Ill is percentage illumination of the Moon


2025-Aug-01 UT 16:45-18:27 Ill=52% Albategnius

     Face of Albategnius: you can see the profile of a face in a shadow 
     from the eastern edge of this crater - 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-01 UT 16:55-17:17 Ill=52% Ptolemaeus

     BAA Request: Examine the floor visually, sketch, or image to 
     show the progression of the shadow spires across floor. If 
     observing visually, how would you describe the appearance of 
     the central lit area on the floor? If imaging, do a time lapse 
     e.g. 1 image per minute to show the progression of the shadow 
     spires. We are asking for these observations following an 
     observation by N. Travnok (Brazil) on 2020 Jul 27 UT 23:00 who 
     commented on an unusual appearance to the floor. It would be 
     really useful to have visual observing of the appearance and 
     please note down what the seeing conditions are like. If you 
     want to image it at high resolution, please go ahead but 
     remember that any image stacking should not be from sections 
     of video of longer than 1 min duration as the shadows change 
     in length rather quickly at sunrise. Any sketches, visual  
     descriptions, or images taken, should be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Aug-01 UT 17:18-19:37 Ill=52% 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 17:15-19:10 Ill=52% 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:
     ALPO - email: c u d n i k @ s b c g l o b a l . n e t
     BAA - email: a t c @ a b e r . a c . u k
     UAI - email: a m . 5 4 8 5 2 @ g m a i l . c o m


2025-Aug-02 UT 16:44-17:03 Ill=61% Plato

     Plato's Hook: a hook like effect in one of the shadow spires in Plato, 
     near a rim - this is a Clair-Obscur effect. It was first seen by 
     H.P.Wilkins in 1952. 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-02 UT 18:01-20:03 Ill=62% Eratosthenes

     ALPO Request: This request comes about because of two 
     observations. Firstly on 2009 Nov 25 Paul Abel and others 
     detected some colour on the inner west illumntated slopes of 
     this crater. No similar colour existed elsewhere. On 2012 Aug 
     25 Charles Galdies imaged this crater and detected a similar 
     colour, approximately in the same location, though he also 
     imaged colour elsewhere. It is important to replicate this 
     observation to see if it was natural surface colour, 
     atmospheric spectral dispersion, or some effect in the camera 
     that Charles was using, namely a Philips SPC 900NC camera. 
     The minimum sized telescope to be used would ideally a 8" 
     reflector. 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-02 UT 18:03-20:00 Ill=62% Clavius

     Eyes of Clavius: you can see this crater with two eyes, Clavius C and 
     Clavius D - 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-05 UT 17:58-19:00 Ill=86% Bullialdus

     ALPO Request: Can you detect any colour, inside the crater, on 
     the floor and elsewhere? Can you image any colour? Minimum 
     telescope aperture needed: 6", and if possible try using a 
     refractor. All images or sketches should be sent 
     to me on this email adrress: a t c @ a b e r . a c. u k 


2025-Aug-05 UT 18:14-18:36 Ill=87% Aristarchus

     BAA Request: Aristarchus area - We are trying to explain an 
     observation from Meudon Observatory in France made in 1881 of 
     a bright rope-like effect seen in the vicinity of this crater.
     Please send any images to: a t c @ a b e r . a c. u k .


2025-Aug-07 UT 21:24-22:22 Ill=97% 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-09 UT 21:51-22:02 Ill=100% Hahn

     BAA Request: On 2012 Jan 09 UT 21:01-21:08 Hahn crater was 
     imaged by Nick Hazel (Beverley, Yorkshire, UK, Nikon D7000 with 
     70-300 zoom at max, with 2x teleconverter, at f9, 1/320 sec, ISO 
     400 – tripod mounted, mirror up), A series of images were taken. 
     The 21:06 one showed a grey column cutting across the central 
     floor of the crater from the west and then bisecting the eastern 
     rim. All detail inside is completely invisble. Some (but not 
     all) of the other images showed a more blurred view of this 
     feature. It is possible that this was a seeing ripple effect, or 
     just the natural appearance of shadings on the Moon at this 
     time, however we would like to capture images of this area to be 
     sure. Small aperture telescopes or telephoto lens similar to 
     Nick's can be used. Try switching the tracking off to see what 
     effect motion blur has during the exposure - to see4 if this 
     replicates the effect. Please send any images you take to:
     a t c @ a b e r . a c . u k


2025-Aug-10 UT 22:16-23:18 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 23:28-02:35 Ill=92% 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 01:47-03:27 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 .
