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 .
ALPO Request: Please supply images, or sketches, of this area,
especially covering the area to the east. Any size scope can be
used for this study. All observations should be emailed 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: On 2013 Aug 26 Peter Grego observed a dark patch
just east of Jansen D. He had not seen this before, therefore it
is important to repeat this observation under simuilar
illumination conditions. It maybe a buried crater? Ideally
suited to scopes of aperture 8" or larger. Please send
any high resolution images, detailed scetches, or
visual descriptions to: a t c @ a b e r . a c. u k .
ALPO Request: Fracatorius - please try to image / sketch /
visually observe the interior shadowed floor of the crater on
the sunset terminator. Can you detect a central bright spot in
the dark dhadow filled floor of the crater? How does its
appearance change over time? Minimum aperture scope to use
9cm. Please send any images to: a t c @ a b e r . a c. u k .

Plato's Hook: a hook like effect in one of the shadow spires in Plato,
near a rim - this is a Clair-Obscur effect. It was first seen by
H.P.Wilkins in 1952. 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: How early can you see the central peak of this
crater illuminated by scattered light off the crater's west
illuminated rim? High resolution and/or long exposures needed
to capture detail inside the floor shadow. All images should
be sent to me on the email adrress below, whether or not you
were successful in capturing the central peak:
