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:
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.

Tycho: "V-shaped pearl neckless" effect - 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. This effect was first spotted by
David Darling in 1992 Aug 21 and was considered to be a possible TLP
until the effect was seen repeated at similar illumination. 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: 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 .

Apollo 17: This is what the lunar surface would have looked like
when Apollo 17 touched down on the Moon. Aim for the area
south of Littrow. 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:
