Ill is percentage illumination of the Moon


2025-Oct-01 UT 08:02-09:01 Ill=63% Copernicus

     BAA Request: On 2012 Sep 24 E. Horner noticed a very strong red 
     colour around part of the sunlit inner rim of Copernicus, 
     sometimes a 1/4 and sometimes 1/2 around the interior. Quite 
     likely this was some form of atmospheric spectral dispersion - 
     though the observer checked for similar effects on other craters 
     but saw none. But to be sure we would like to obtain some colour 
     images or visual observations of this crater. The minimum sized 
     telescope to be used would ideally a 6" reflector. Low elevation 
     angles for the Moon are ideal as we want to try to replicate 
     this effect if it is indeed due to atmospheric spectral 
     dispersion. Please send any high resolution images, detailed 
     sketches, or visual descriptions 
     to: a t c @ a b e r . a c. u k .


2025-Oct-01 UT 08:17-09:15 Ill=63% Apollo_17

     Apollo 17: This is what the lunar surface would have looked like when 
     Apollo 17 blasted off from the Moon. Aim for the area 
     south of Littrow. 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-Oct-06 UT 04:36-05:35 Ill=99% Bailly

     BAA Request. Please observe visually or image this crater in 
     colour to see if you can detect any colour on part of the 
     floor. Please email any observations to:
     a t c @ a b e r . a c. u k .


2025-Oct-08 UT 11:53-12:27 Ill=97% 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-Oct-09 UT 15:31-15:45 Ill=91% Torricelli_B

     BAA Request: Sketches or images needed of Toricelli B - of 
     sufficient resolution to reveal shadow. All observations, 
     including sketches or images shouild be emailed to: 
     a t c @ a b e r . a c. u k .


2025-Oct-10 UT 07:41-15:45 Ill=85% 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-Oct-11 UT 13:40-14:39 Ill=74% 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-Oct-11 UT 14:04-14:39 Ill=74% 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-Oct-26 UT 05:02-06:55 Ill=18% 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-Oct-26 UT 04:22-05:06 Ill=18% Earthshine: sporadic meteors

2025-Oct-28 UT 04:57-05:16 Ill=35% Apianus_D

     BAA Request: On 2011 Oct 03 Fran Power both observed visually a 
     range of colours on the rim of this crater. Although the Moon 
     was quite low in the sky, this effect was not seen anywhere else 
     on the Moon. The appearance was confirmed by another observer 
     using the same telescope (without being told what they were 
     supposed to see). An image was obtained which seems to show some 
     strong colour in this specific location, and nowhere else. 
     Please re-observe this area. Telescopes of aperture 6" and 
     larger are needed (refractors not allowed) - observations with 
     the Moon low down in the sky are desirable to see if the 
     atmosphere can reporduce this effect. Please send any sketches 
     or images to: a t c @ a b e r . a c . u k


2025-Oct-28 UT 05:16-05:26 Ill=35% Maurolycus

     ALPO Request: On 2012 Feb 28 Raffaello Braga noted that only the 
     tip of the central peak was visible. Most of the crater was in 
     darkness - this was normal at this stage in illumination. When 
     viewed through a red filter, the central peak was visble, but 
     however when viewed through a blue filter it was invisible. 
     Please try to observe this crater visually with red and blue 
     filters, to see if you can replicate this effect? If so then 
     check for similar effects on other craters on the terminator. 
     Otherwise try to obtain some high resolution colour images. This 
     work is suitable for telescopes of 4" aperture or larger - if 
     you have a choice of a efractor or a reflector, please try the 
     refractor. Please send any observations you make to:
     a t c @ a b e r . a c . u k


2025-Oct-28 UT 04:21-06:58 Ill=36% 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-Oct-29 UT 04:03-05:40 Ill=45% 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-Oct-29 UT 04:54-06:51 Ill=45% 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-Oct-29 UT 05:41-08:25 Ill=45% 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-Oct-29 UT 04:20-07:59 Ill=46% 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-Oct-30 UT 03:53-05:32 Ill=55% 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-Oct-30 UT 06:13-08:32 Ill=56% 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-Oct-30 UT 06:32-08:29 Ill=56% 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-Oct-31 UT 08:20-09:18 Ill=67% Apollo_14

     Apollo 14: This is what the lunar surface would have looked like 
     when Apollo 14 touched down on the Moon. Aim for the area 
     north of Fra Mauro. 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-Oct-31 UT 09:40-10:26 Ill=67% Apollo_12

     Apollo 12: This is what the lunar surface would have looked like 
     when Apollo 12 touched down on the Moon. Aim for the area 
     SW of Lansberg. 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
