2025-Aug-01 UT 10:22-10:36 Ill=49% Ukert
2025-Aug-01 UT 10:22-10:36 Ill=49% Werner

     Werner: an "X" on the Moon - 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-Aug-01 UT 10:49-13:47 Ill=50% 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
     BAA - email: a t c @ a b e r . a c . u k
     UAI - email: a m . 5 4 8 5 2 @ g m a i l . c o m


2025-Aug-02 UT 11:40-12:50 Ill=59% Lassell

     BAA Request: Lassell - we are trying to compare a sketch made 
     by T.G. Elger (1883 Jan 13 UT 19:40), that appeared on the 
     front cover of the BAA's The Moon publication from 1956 Vol 5 
     No. 2, to what can be captured with modern day imagery. This 
     is a good way to compare and contrast observations made by eye 
     with CCD imagery.Telescopes of aperture 8", or larger, should 
     be used. Please send any images to: 
     a t c @ a b e r . a c. u k .


2025-Aug-02 UT 13:08-14:46 Ill=59% 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-Aug-02 UT 13:55-14:30 Ill=60% Tycho

     BAA Request: How early can you see the central peak of this 
     crater illuminated by scattered light off the crater's west 
     illuminated rim? High resolution and/or long exposures needed 
     to capture detail inside the floor shadow. All images should 
     be sent to me on the email adrress below, whether or not you 
     were successful in capturing the central peak: 
     a t c @ a b e r . a c. u k 


2025-Aug-05 UT 11:49-12:46 Ill=85% 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-Aug-05 UT 11:56-13:53 Ill=85% 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-Aug-06 UT 12:44-13:01 Ill=91% Prinz

     ALPO Request: Compare the crater in red and blue light - if 
     possible use Wratten 25 and Wratten 38A filters. If its 
     brighter in one filter than the other, is this because one 
     filter is a lot darker than the other, or is the effect 
     confined only to this crater? Any visual descriptions, 
     sketches, or colour 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-Aug-08 UT 12:46-14:43 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-Aug-10 UT 12:22-12:36 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-Aug-11 UT 15:36-16:57 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-Aug-12 UT 13:40-19:08 Ill=87% 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-13 UT 14:21-14:38 Ill=78% 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 .

     ALPO Request: There is a bright spot on the NW shore of Mare 
     Crisium, which is normal. However please check its appearance 
     in a blue filter e.g. Wratten 38A. A minimum sized scope for 
     this task is 4" (ideally a refractor) with a magnification of 
     around x180. If taking colour imagery, please make sure that 
     the exposure is short enough so that the bright spot does not 
     saturate. All visual reports and colour images should be 
     emailed to:

2025-Aug-30 UT 10:32-12:29 Ill=42% 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-Aug-31 UT 13:16-14:06 Ill=52% Picard

     ALPO Request: Is there a dark patch surrounding this crater 
     tonight? We are just checking up on the normal appearance of 
     this crater and its surrounds, to verify an observational 
     report from 1994 during the ALPO Clementine watch. Use a 
     telescope of aperture 3.5 inches or larger. All sketches or
