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 .
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: Take high resolution images of the area north of
Descartes to capture a view of what the lunar surface would
have looked like from Earth at the moment Apollo 16 touched
down on the Moon. Minimum diameter scope 20cm, larger
apertures preferred:

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.

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:
