BAA Request: Any colour visble on the south wall and floor of
this crater? Check with red and blue filters e.g. Wratten 25 and
44, else obtain some colour images, taking care to under expose
slightly so as not to saturate the mountain. Any sketches,
visual descriptions, or images taken, should be emailed to:
a t c @ a b e r . a c. u k .
BAA Request: On 2011 Jan 21 Nigel Longshaw suspected the
eastern side of Geminus (on the border of the crater filled
shadow and the eastern illuminated rim) had a colouration to
it. This extended for a short distance from the floor shadow
into the illuminated rim width and spanned from the north to
the south of the crater. For a comparison, Cleomedes was
checked but nothing unusual was noticed in its shadow. The
observer notes that Elger also saw colour here too. Its
probable that some natural surface colouration was observed,
but this needs to be checked out? Telescopes of aperture 4"
or larger are needed to observe this effect. If you have a
refractor, then try using this, otherwise a reflector will do
just as well. Please send any sketches, images, 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

ALPO Request: Any colour visible on the northern edge? Check
with filters if you are observing visually. Otherwise use
colour imaging.Please use a telescope of aperture 20cm or
larger. Any visual descriptions, sketches, or images should
be emailed to:

Cassini's Moon Maiden at Promontorium Heraclides - 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 should be possible at this colongitude to
sketch or image two light spots on the floor of Herodotus, which
may have been mistaken for peaks/small hills in the past? The
first should be on the southern floor and the second should be
to the NW of the crater centre. Any images/sketches should be
emailed to:

BAA Request: On 2010 Apr 27 Peter Grego noticed a craterlet
just to the east of Briggs (this is normal), but also an E-W
trending lineament or wrinkle ridge that does not show up on
NASA LAC charts - it is this we wish to confirm by re-
observing under similar seleonographic colongitudes. An 8" or
larger telecope is required, Please send any high resolution
images, detailed sketches, or visual descriptions to:
