Ill is percentage illumination of the Moon


2025-Sep-01 UT 19:55-20:54 Ill=65% 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-Sep-02 UT 22:35-23:33 Ill=75% Apollo_15

     Apollo 15: This is what the lunar surface would have looked like when 
     Apollo 15 blasted off from 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-Sep-03 UT 23:13-00:10 Ill=83% Aristarchus

     ALPO Request: On 2013 Apr 22 Paul Zellor noticed that the two 
     closely spaced NW dark bands in Aristarchus had some (non-blue) 
     color to them. Can we confirm his observation of natural colour 
     here? Ideally you should be using a telescope of 10" aperture, or 
     larger. Please send any high resolution color images, detailed 
     sketches, or visual descriptions to: a t c @ a b e r . a c. u k .


2025-Sep-03 UT 23:19-00:54 Ill=83% Torricelli_B

     BAA Request: Any sign of colour on this crater? Exmaine it 
     through red and blue filters e.g. Wratten 28 and 44A. Also 
     would you say that the crater looks dull? We are especially 
     interested if you observe the cxrater under poor transparency 
     conditions. All observations, including visual descriptions, 
     sketches, or images should be emailed to: 
     a t c @ a b e r . a c. u k .


2025-Sep-07 UT 00:14-00:35 Ill=99% Copernicus

     ALPO Request: Can you see a darkening on the northen floor of 
     this crater? All visual reports, sketches or color 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 01:45-02:43 Ill=93% Cleomedes

     BAA Request: In 1991 Dec 23 Bob Mizon (BAA) sketched the 
     crater Cleomedes and Mare Cisrium. In the floor of the shadow 
     filled Cleomedes was an dusky oval area - presumably the last 
     rays of the Sun reaching the floor. We would like yuo to 
     either sketch, or image, over time, how the shape of this oval 
     area changes, and eventually vanishes. How late in terms of 
     colongitude can it still be seen? Is there any hint of colour 
     present? Telescopes of aperture 6 inche or larger should be 
     used. Please send any observation 
     you make to: 
     a t c @ a b e r . a c . u k


2025-Sep-10 UT 03:08-04:13 Ill=93% 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-Sep-10 UT 20:59-04:12 Ill=86% 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=76% 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=76% 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-25 UT 18:06-18:47 Ill=13% Yerkes

     Yerkes: a "Woodpecker" shaped shadow - 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. This particular Clair-Obscur effect was first
     reported by KC Pau.


2025-Sep-25 UT 17:12-18:26 Ill=13% Earthshine: (radio shower) Kappa Leonids

     These can only be observed using low-light level cameras running at 25 frames per sec,

2025-Sep-26 UT 17:03-18:03 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-26 UT 17:12-19:18 Ill=21% Earthshine: (radio shower) September Sextantids: ZHR=5 vel=32km/s

     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.

2025-Sep-28 UT 17:58-18:18 Ill=38% Torricelli

     ALPO Request: On 2011 Dec 31 Raffaello Braga found the north rim 
     or Torricelli to be very bright at the start of the observing 
     session but dimmed considerably later. He was not sure on the 
     normal appearance of this crater, hence why it is really 
     imortant to establish this by re-observing under similar 
     illumination. Minimum telescope aperture required: 3", and try 
     to use a refractor if possible. 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-28 UT 17:13-21:03 Ill=39% 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 16:47-17:50 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 16:47-21:46 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-29 UT 17:13-21:56 Ill=49% 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-30 UT 17:29-19:26 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.


2025-Sep-30 UT 17:53-19:29 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 22:12-23:08 Ill=59% Tycho

     ALPO Request: Try viewing the central peak through a red and 
     blue filter e.g. Wratten 25a and 38, and comparing the 
     brightness to the  of the eastern sunlit rim. Does the size 
     of the central peak change between filters? If you do detect 
     colour here, obviously check for colour on other central 
     peaks. If taking colour images, make sure that you do 
     nderexpose slightly so as to avoid saturating the central 
     peak. All visual reports, sketches or colour images should be  
     emailed to:
