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 touched down on the Moon. Minimum diameter scope 20cm, larger apertures preferred: a t c @ a b e r . a c . u k
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

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
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
BAA Request: On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by Nick Hazel (Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max, with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod mounted, mirror up), A series of images were taken. The 21:06 one showed a grey column cutting across the central floor of the crater from the west and then bisecting the eastern rim. All detail inside is completely invisble. Some (but not all) of the other images showed a more blurred view of this feature. It is possible that this was a seeing ripple effect, or just the natural appearance of shadings on the Moon at this time, however we would like to capture images of this area to be sure. Small aperture telescopes or telephoto lens similar to Nick's can be used. Try switching the tracking off to see what effect motion blur has during the exposure - to see4 if this replicates the effect. Please send any images you take to: a t c @ a b e r . a c . u k
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
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: t o n y . c o o k @ a l p o - a s t r o n o m y . o r g
