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: 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: 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: 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: We need observations of this region to see if you can detect a darkening effect that was seen in 1994. Please observe at regular intervals e.g. every 10 minutes. You need a telescope of aperture 3.5 inches or above in diameter to take part. Please send any sketches, images captured, or even visual descriptions 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
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
