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: 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
BAA Request: Images needed of the area around this crater,
including the nearby terminator. Any images should be
emailed to:

Ukert: a "V" on the Moon - this is a Clair-Obscur effect.
Clair-Obscur have no scientific importance and are just tricks of the
light that make us think we see something like a letter of the alphabet
or a shape or face. Clair-Obscur effects are scientifically pointless
to observe. However, if you want to be thrilled, or obtain an image to
impress someone then give them a go. If you do observe, or image this,
by all means send your observation into ALPO or the BAA, but we
probably won't publish, but will nevertheless retain in our archives,
just in case features elsewhere in the image are of interest to
future researchers.

BAA Request: It has been noticed that a bright carterlet can
appear very suddenly on the floor of Plato in between needle
like shadows, during local lunar sunrise. This happens in the
space of just a minute or so, and can look really quite dramatic.
This effect was first spotted by Brian Halls on 2014 Oct 31

visual descriptions to: a t c @ a b e r . a c. u k .
BAA Request: On 2012 Sep 24 E. Horner noticed a very strong red
colour around part of the sunlit inner rim of Copernicus,
sometimes a 1/4 and sometimes 1/2 around the interior. Quite
likely this was some form of atmospheric spectral dispersion -
though the observer checked for similar effects on other craters
but saw none. But to be sure we would like to obtain some colour
images or visual observations of this crater. The minimum sized
telescope to be used would ideally a 6" reflector. Low elevation
angles for the Moon are ideal as we want to try to replicate
this effect if it is indeed due to atmospheric spectral
dispersion. Please send any high resolution images, detailed
sketches, or visual descriptions
to: a t c @ a b e r . a c. u k .
Apollo 15: This is what the lunar surface would have looked like when
Apollo 15 blasted off from the Moon. Aim for the area
of Rima Hadley. The illumination and the shadows are
exactly the same. There is no scientific value in imaging
this, but from the nostalgic point of view it might be interesting
to observe. Feel free to send your observation in to the BAA or
ALPO and we will put it in our archives, but as we have
a lot of these images already, we may not publish it, unless it is
exceptionally high in resolution. Minimum diameter scope to use
would be 20cm, but larger apertures are preferred:
ALPO Request: On 1989 Feb 17 David Darling made an observation
about the brightness of the east and west walls of Proclus. We
would like you to image, sketch, or just visually note which
is brighter, the east or the west rim of this crater?
Telescopes of aperture 6 inche or larger should be used.
Please send any observation you make to:

Apollo 14: This is what the lunar surface would have looked like
when Apollo 14 blasted off from the Moon. Aim for the area
north of Fra Mauro. The illumination and the shadows are

to observe. Feel free to send your observation in to the BAA or

ALPO Request: On 2013 Apr 22 Paul Zellor noticed that the two
closely spaced NW dark bands in Aristarchus had some (non-blue)
color to them. Can we confirm his observation of natural colour
here? Ideally you should be using a telescope of 10" aperture, or
larger. Please send any high resolution color images, detailed
sketches, or visual descriptions to: a t c @ a b e r . a c. u k .
