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
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.
These can only be observed using low-light level cameras running at 25 frames per sec,

Monte Caucasus: "shadow face" silhouette Clair-Obscur effect.
Clair-Obscur effects have no scientific importance 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 useless to observe. However, if
you want to be thrilled, or obtain an image to impress someone
then give them a go. This effect on the southern end of Montes
Caucuses looks like the side silhouette of a cartoon human face.
We are still slightly undertain about the precise colongitude
range, so if you do not see the face, try again later. 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.
Note that we have some uncertainty in the colongitude range
- so if you don't see it, please tells us the date and UT so
we can make some improvements in the predictions.

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 .
