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: Take high resolution images of the area south of Littrow to capture a view of what the lunar surface would have looked like from Earth at the moment Apollo 17 touched down on the Moon. Minimum diameter scope 20cm, larger apertures preferred: a t c @ a b e r . a c . u k

ALPO Request: We have reports of details visible in the shadows of Apianus and Faraday craters. Just curous to see if this effect repeats. Please take some exposures of sufficient length to be able to see shadings in the shadows of these, and neighboring, craters. Do not use excessive sharpening on the images. Please email these to: a t c @ a b e r . a c . u k

ALPO Request: Try viewing the central peak through a red and blue filter e.g. Wratten 25a and 38, and comparing the brightness to the of the eastern sunlit rim. Does the size of the central peak change between filters? If you do detect colour here, obviously check for colour on other central peaks. If taking colour images, make sure that you do nderexpose slightly so as to avoid saturating the central peak. 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
BAA Request: On 2012 Sep 24 E. Horner noticed a very strong red colour around part of the sunlit inner rim of Copernicus, sometimes a 1/4 and sometimes 1/2 around the interior. Quite likely this was some form of atmospheric spectral dispersion - though the observer checked for similar effects on other craters but saw none. But to be sure we would like to obtain some colour images or visual observations of this crater. The minimum sized telescope to be used would ideally a 6" reflector. Low elevation angles for the Moon are ideal as we want to try to replicate this effect if it is indeed due to atmospheric spectral dispersion. Please send any high resolution images, detailed sketches, or visual descriptions to: a t c @ a b e r . a c. u k .
BAA Request: How dark is the floor of Plato compared to other dark areas on the Moon e.g. nearby Mare. Can you see central craterlet on the floor? Is the floor of Plato brighter or darker through a green filter than in other colours? Alternatvely just take a colour image. Mimimum sized telescope aperture: 6 inches.Please send any sketches, monochrome images, or visual reports to: a t c @ a b e r . a c. u k .
ALPO Request: On 1989 Feb 17 David Darling made an observation about the brightness of the east and west walls of Proclus. We would like you to image, sketch, or just visually note which is brighter, the east or the west rim of this crater? Telescopes of aperture 6 inche or larger should be used. Please send any observation you make to: a t c @ a b e r . a c . u k
BAA Request: Some astronomers have occasionally reported seeing a pseudo peak on the floor of this crater. However there is no central peak! Please therefore image or sketch the floor, looking for anything near the centre of the crater resembling a light spot, or some highland emerging from the shadow. All reports should be emailed to: a t c @ a b e r . a c . u k
ALPO Request: The area to look at here is to the west of Herodotus, near the terminus of Valles Schroteri, where you should be able to see four spots of light (just east of the terminator). Are these better visible in red or blue light? The original observation was made using Wratten 38A and Wratten 25 filters, but any blue and red filters will do, or indeed a colour camera. Do these spots fade over time? If so, in what order? If imaging, then time lapse imaging would be useful here. Minimum aperture telescope to use should be a 6", and if possible a refractor - aim to use magnifications of around 114x to 228x. Any visual descriptions, sketches of images should be emailed to: a t c @ a b e r . a c. u k .
BAA Request: Look for colour along the edge od the SW ray between Aristarchus and Herodotus. Mimimu sized telescope diameter 8". Try to use a magnification of between 100 and 200x. Use red, blue filters to verify colour e.g. Wratten 25 and Wratten 44a. Otherwise use colour imaging - but keep the exposure short enough to avoid saturating Aristarchus or the SW ray. Any sketches or colour images should be emailed to: a t c @ a b e r . a c . u k
