Ill is percentage illumination of the Moon


2025-Aug-01 UT 00:00-00:32 Ill=44% Descartes

     ALPO Request: On 2010 Apr 20 Ivan Bryukhanov observed an 
     orange-brown tint a little to the west of Zollner and Kant 
     craters. A refractor would be suitable for this, although any 
     sized scope larger than 4.5" aperture would suffice. Its 
     possible that this might have been related to the low 
     altitude of the Moon, therefore observing with the Moon down to 
     about 15-5deg above the horizon is acceptable for this to see if 
     we can replicate colour here. Please send any images, detailed 
     sketches, or visual descriptions to: a t c @ a b e r . a c. u k 


2025-Aug-01 UT 00:00-01:10 Ill=44% 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 00:00-01:12 Ill=45% 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

2025-Aug-01 UT 23:00-23:22 Ill=54% Archimedes

     BAA Request: Please image or sketch this area, looking 
     especially for two bright points of light on the edge of the 
     termiator. A scope of at least 4" aperture is needed for this 
     observation. All images or sketches should be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Aug-01 UT 21:03-02:01 Ill=55% Earthshine: sporadic meteors

2025-Aug-03 UT 02:42-03:13 Ill=64% Tycho

     BAA Request: Can you see any sign of "greyness" inside the 
     shadow on the floor of Tycho? This is possibly due to 
     scattered light off of the illuminated walls of Tycho. Mimimum 
     sized aperture telescope to use should be an 8" reflector. Any 
     visual descriptions, sketches or slightly over exposed images 
     should be emailed to:
     a t c @ a b e r . a c. u k 


2025-Aug-03 UT 23:32-01:29 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

2025-Aug-05 UT 00:19-02:16 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

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 23:18-00:13 Ill=96% 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 03:47-05:20 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-12 UT 00:16-08:38 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-30 UT 20:44-21:55 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

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 .
