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: 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.

BAA Request: Eudoxus - please try to image the interior of
this crater. We are trying to explain an observation from
Meudon Observatory in France made in 1877 for which a fine
line of light was seen acress the crater in an E-W direction.
Please send any images to: a t c @ a b e r . a c. u k .

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 .
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
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: 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. Please observe visually or image this crater in
colour to see if you can detect any colour on part of the
floor. Please email any observations 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.
