2025-Sep-01 UT 05:23-07:20 Ill=59% 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-01 UT 05:50-07:24 Ill=59% 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-04 UT 05:37-06:00 Ill=86% 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-04 UT 05:47-06:24 Ill=86% Bullialdus

     ALPO Request: Can you detect any colour, inside the crater, on 
     the floor and elsewhere? Can you image any colour? Minimum 
     telescope aperture needed: 6", and if possible try using a 
     refractor. All images or sketches should be sent 
     to me on this email adrress: a t c @ a b e r . a c. u k 


2025-Sep-06 UT 08:51-09:49 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 11:01-15:37 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-30 UT 05:04-05:27 Ill=52% Alphonsus

     ALPO Request: What can you see in the way of a light patch 
     inside the crater (of a diameter of approximately 10km). If 
     visible, how long does it last for? If imaging, make sure you 
     allow a suitable exposure. If visual observing, sometimes a 
     lower magnification can help to improve image contrast. Please 
     use a telescope of aperture 20cm or larger. Any visual 
     descriptions, sketches, or images should be emailed to:
