Ill is percentage illumination of the Moon


2025-Sep-01 UT 01:28-03:33 Ill=58% 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-04 UT 05:37-06:00 Ill=85% Aristarchus

     BAA Request: Aristarchus area - We are trying to explain an 
     observation from Meudon Observatory in France made in 1881 of 
     a bright rope-like effect seen in the vicinity of this crater.
     Please send any images to: a t c @ a b e r . a c. u k .


2025-Sep-06 UT 08:51-09:30 Ill=97% Plato

     BAA Request: Two observers have reported colour on the rim 
     around this colongitude, once in 1938, and again in 2013. Please 
     take a look and report what you see, and where on the rim. 
     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-10 UT 03:41-04:30 Ill=92% 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 11:01-06:42 Ill=90% 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-28 UT 01:31-02:06 Ill=32% Santbech

     BAA Request: We need colour images of Earthshine, including the 
     approximate area in the vicinity of Santbech crater. You can use 
     a telescope with an aperture of 3" of larger (if possible use a 
     refractor). This is to see what effects in our atmosphere, or 
     telescope optics, can replicate some glows seen visually back in 
     1994. Any images should be emailed to:
     a t c @ a b e r . a c. u k .
