2025-Jun-03 UT 17:26-18:13 Ill=55% Ptolemaeus

     BAA Request: Examine the floor visually, sketch, or image to 
     show the progression of the shadow spires across floor. If 
     observing visually, how would you describe the appearance of 
     the central lit area on the floor? If imaging, do a time lapse 
     e.g. 1 image per minute to show the progression of the shadow 
     spires. We are asking for these observations following an 
     observation by N. Travnok (Brazil) on 2020 Jul 27 UT 23:00 who 
     commented on an unusual appearance to the floor. It would be 
     really useful to have visual observing of the appearance and 
     please note down what the seeing conditions are like. If you 
     want to image it at high resolution, please go ahead but 
     remember that any image stacking should not be from sections 
     of video of longer than 1 min duration as the shadows change 
     in length rather quickly at sunrise. Any sketches, visual  
     descriptions, or images taken, should be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Jun-04 UT 13:46-14:56 Ill=64% 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-Jun-04 UT 16:02-16:36 Ill=64% 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-Jun-06 UT 13:32-14:30 Ill=81% Apollo_16

     BAA Request: Take high resolution images of the area north of 
     Descartes to capture a view of what the lunar surface would 
     have looked like from Earth at the moment Apollo 16 lifted off 
     of the Moon. Minimum diameter scope 20cm, larger 
     apertures preferred: 
     a t c @ a b e r . a c . u k


2025-Jun-07 UT 13:56-14:53 Ill=88% 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-Jun-07 UT 18:58-19:55 Ill=88% 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-Jun-08 UT 13:58-15:01 Ill=93% Aristarchus

     ALPO Request: Take a look at the bright area on the crater 
     floor, and the bright east facing part of the western rim, in 
     red and blue light e.g. Wratten 25 and 38A. Do these look 
     brighter to you in red or blue light? If you have these filters, 
     is it the fact that the Wratten 38A filter, being denser, makes 
     these areas brighter in one filter than in the other? Test them 
     out on other features. 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-Jun-13 UT 16:41-17:04 Ill=94% Tycho

     BAA Request: Compare the brightness of Tycho with Cassini and 
     a bright spot in Delandres. Use red and violet filters. 
     Telescopes of apertures as small as 2.5" can be used for this 
     study (if possible a refractor) with a magnifiaction of 
     around x50. Colour imagery can also be used providing that 
     the exposure is short enough to avoid saturation on bright 
     features. Any visual descriptions, sketches or images should 
     be emailed to:
     a t c @ a b e r . a c. u k 


2025-Jun-13 UT 17:40-19:02 Ill=94% 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-Jun-14 UT 16:56-21:12 Ill=88% 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-Jun-18 UT 20:21-21:43 Ill=49% Tycho

     ALPO Request: What we are interested in here is time sequences 
     sketches or images of the central peak and shadowed interior 
     of the floor of this crater. Can you see any detail inside the 
     shadow? Is the shadow completely black in colour or is there 
     some greyness? How does the brightness of the central peak 
     change over time? All visual reports, sketches or colour 
     images should be emailed to:
