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:

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 .
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:

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.
