Ill is percentage illumination of the Moon


2025-Aug-10 UT 22:16-22:54 Ill=97% 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 23:28-01:17 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


2025-Aug-15 UT 22:08-02:10 Ill=52% Earthshine: Kappa Cygnids: ZHR=5 vel=21km/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.
     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-Aug-17 UT 01:47-03:02 Ill=40% Plato

     BAA Request: Its around this Co-Longitude that some observers 
     have reported seeing an Ashen Light effect on the shadowed floor 
     of Plato, caused by scattered light off of an illuminated peak 
     on the rim. Please have a go either visually, or with long 
     exposure time lapse imagery to see if you can pick up the 
     development of this weak illumination effect on the floor. 
     Please send any sketches or images to: 
     a t c @ a b e r . a c. u k .


2025-Aug-16 UT 22:41-02:12 Ill=40% 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.
