BAA Request: Please try to image the Moon as a very thin crescent, tryimg to detect Earthshine. A good telephoto lens will do on a DSLR, or a camera on a small scope. We are attempting to monitor the brightness of the edge of the earthshine limb in order to follow up a project suggested by Dr Martin Hoffmann at the 2017 EPSC Conference in Riga, Latvia. This is quite a challenging project due to the sky brightness and the low altitude of the Moon. Please do not attempt if the Sun is still above the horizon. Do not bother observing if the sky conditions are hazy. Any images should be emailed to: a t c @ a b e r . a c . u k
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
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 morning, that it starts to show 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

BAA Request: Images or sketches of this crater needed. We are trying to see if a curious gray band is visible across the crater floor as seen by T. Smith on 2020 Nov 22. Any sized scope can be used from 5" or upwards. All images should be sent to: a t c @ a b e r . a c . u k
BAA Request: Eudoxus - please try to image the interior of this crater. We are trying to detect bright spots and a linear features within the shadow of the east wall at sunrise. Nigel Longshaw (BAA) suspects that this might explain Trouvelot's obsevation in 1877 of a luminous rope-like feature. Please send any images to: a t c @ a b e r . a c. u k .
BAA Request: Eudoxus - please try to image or skecth the crater. This is to try to explain a line of light effect seen inside this crater by French astronomer Trouvelot back in Victorian times. The BAAs Nigel Longshaw says that this may be seen between colongitudes of 0.3 to 1.2 degrees. Please send any images or sketches to: 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: It has been noticed that a bright carterlet can appear very suddenly on the floor of Plato in between needle like shadows, during local lunar sunrise. This happens in the space of just a minute or so, and can look really quite dramatic. This effect was first spotted by Brian Halls on 2014 Oct 31 Please send any high resolution images, detailed scetches, or visual descriptions 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
BAA Request: Take high resolution images of Rimma Hadley to capture a view of what the lunar surface would have looked like from Earth at the moment Apollo 15 lifted off from the Moon. Minimum diameter scope 20cm, larger apertures preferred: a t c @ a b e r . a c . u k
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 .
BAA Request: Please either observe visually with red and blue filters, or image with a colour webcam, the floor of this crater. On two occasiobns colour was detecred here which might be natural or more likley a combination of poor seeing conditions and atmospheric spectral dispersion (or chromatic aberation) on a bumpy area of the floor of this crater. Minimum aperture used should be 6" or 15cm. Any visual descriptions, sketches, or images should be emailed to: a t c @ a b e r . a c . u k
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
