Ill is percentage illumination of the Moon


2025-Sep-01 UT 15:43-16:35 Ill=63% Picard

     ALPO Request: Can you resolve any details inside Picard tonight? 
     Is it surrounded by a nebulous patch? We are just checking up on 
     the normal appearance of this crater and its surrounds, to 
     verify an observational report from 1994 during the ALPO 
     Clementine watch. Use a telescope of aperture 6 inches or 
     larger. All sketches or monochrome images should be emailed 
     to: t o n y . c o o k @ a l p o - a s t r o n o m y . o r g


2025-Sep-08 UT 23:32-00:07 Ill=98% Mons_Vinogradov

     ALPO Request: Please supply images, or sketches, of this area, 
     especially covering the area to the east. Any size scope can be 
     used for this study. All observations should be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Sep-10 UT 17:34-01:27 Ill=88% 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-Sep-12 UT 01:14-02:13 Ill=77% Jansen

     BAA Request: On 2013 Aug 26 Peter Grego observed a dark patch 
     just east of Jansen D. He had not seen this before, therefore it 
     is important to repeat this observation under simuilar 
     illumination conditions. It maybe a buried crater? Ideally 
     suited to scopes of aperture 8" or larger. Please send 
     any high resolution images, detailed scetches, or 
     visual descriptions to: a t c @ a b e r . a c. u k .


2025-Sep-12 UT 01:38-02:12 Ill=77% Fracastorius

     ALPO Request: Fracatorius - please try to image / sketch / 
     visually observe the interior shadowed floor of the crater on 
     the sunset terminator. Can you detect a central bright spot in 
     the dark dhadow filled floor of the crater? How does its 
     appearance change over time? Minimum aperture scope to use 
     9cm.  Please send any images to: a t c @ a b e r . a c. u k .

2025-Sep-26 UT 16:06-16:25 Ill=20% Mutus_F

     BAA Request: Can you see, or image, 4 points of light in the 
     shadowed floor of the crater? How do these change in 
     appearance over time? This is not a TLP but is still 
     interesting to observe as it might look like a string of 
     pearls effect. Please send any images, or sketches, to: 
     a t c @ a b e r . a c. u k 


2025-Sep-28 UT 14:48-15:13 Ill=37% Earthshine: sporadic meteors

2025-Sep-29 UT 14:42-16:39 Ill=46% 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-Sep-29 UT 15:53-16:52 Ill=47% 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-Sep-29 UT 14:47-16:04 Ill=47% 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

2025-Sep-29 UT 16:40-16:52 Ill=47% 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-Sep-30 UT 14:16-16:28 Ill=56% 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-Sep-30 UT 17:09-17:56 Ill=57% 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-Sep-30 UT 17:29-17:56 Ill=57% 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.
