Ill is percentage illumination of the Moon


2026-Aug-01 UT 10:15-11:37 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

2026-Aug-21 UT 03:07-03:24 Ill=60% Deluc_H

     SLA Request: Deluc H. On 2019 Oct 06 Alberto Anunziato 
     observed an rapid change in appearance (few tens of minutes) 
     in relation to west rim - presumably an illumination effect. 
     Please submit any sketches or images of this crater to me and 
     it will be passed onto the SLA. Please email these to: 
     a t c @ a b e r . a c. u k 


2026-Aug-22 UT 05:10-05:17 Ill=69% 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 .


2026-Aug-25 UT 06:36-07:43 Ill=92% Cavendish_E

     BAA Request: Cavendish E - we are attempting to check out two 
     reports made on 2021 Jun 22 UT 20:44 and 2025 Sep 04 UT 20:04 
     which both said that part of the northern rim of this crater 
     was as bright as Aristarchus. Visual observation or images 
     - high resolution and/or wide angle (to compare with other 
     bright features) would be welcome. Telescopes of aperture 5", 
     or larger, should be used. Please send any images to: 
     a t c @ a b e r . a c. u k .


2026-Aug-29 UT 08:42-09:16 Ill=99% 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 


2026-Aug-30 UT 10:54-11:36 Ill=95% 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:
