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 be very careful around sunrise so as not to be observing once the Sun has risen. 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

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 north of Moltke to capture a view of what the lunar surface would have looked like from Earth at the moment Neil Armstrong made the first footprint on the lunar surface.

ALPO Request: This request comes about because of two observations. Firstly on 2009 Nov 25 Paul Abel and others detected some colour on the inner west illumntated slopes of this crater. No similar colour existed elsewhere. On 2012 Aug 25 Charles Galdies imaged this crater and detected a similar colour, approximately in the same location, though he also imaged colour elsewhere. It is important to replicate this observation to see if it was natural surface colour, atmospheric spectral dispersion, or some effect in the camera that Charles was using, namely a Philips SPC 900NC camera. The minimum sized telescope to be used would ideally a 8" reflector. 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: On 2010 Apr 27 Peter Grego noticed a craterlet just to the east of Briggs (this is normal), but also an E-W trending lineament or wrinkle ridge that does not show up on NASA LAC charts - it is this we wish to confirm by re- observing under similar seleonographic colongitudes. An 8" or larger telecope is required, 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: Two observers have reported colour on the rim around this colongitude, once in 1938, and again in 2013. Please take a look and report what you see, and where on the rim. 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: 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: Tycho. We are trying to replicate, using modern day images, a sketch in Plate X in BAA The Moon from published: 1950 Jun Vol 1, No. 1. It is for a sketch made by H.P. Wilkins from 1949 Jun 05. The original sketch was made with an 12" telescope. Please send any images to: a t c @ a b e r . a c. u k .
BAA Request: Do the appearance of the bands on the crater rim vary (blur) in appearance over time? Compare them to bands in other craters e.g. Herodotus, Kepler, Copernicus. If you do see any variations in sharpness, see how it relates to atmospheric seeing condtions. All images or sketches should be emailed 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: Is there a coloured spot on the western wall? Try using coloured filters e.g. Wratten 29 and 38. 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

BAA Request: Its around this Co-Longitude that some observers have reported seeing an Ashen Light effect on the shadowed floor of Plato, caused by scattered light off of an illuminated peak on the rim. Please have a go either visually, or with long exposure time lapse imagery to see if you can pick up the development of this weak illumination effect on the floor.
