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 .
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.
Dates/UTs of observing runs, or detections of impacts, should be emailed to:

BAA Request: Can you see, or image, 4 points of light in the
shadowed floor of the crater? How do these change in
appearance over time? This is not a TLP but is still
interesting to observe as it might look like a string of
pearls effect. Please send any images, or sketches, 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: Is there a dark shaded area on the floor of size
approximately ~1/4 diameter of Sinus Iridum and on western
interior by the rim? Telescopes as small as 2" apperture can be
used for this study at a magnification of approximately 110x.
Any visual descriptions, sketches or images should be emailed
to:
a t c @ a b e r . a c. u k .
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: Gutenberg Clefts. We are trying to replicate,
using modern day images, a sketch in Plate III in BAA The Moon
from published: 1950 Jun Vol 1, No. 1. Its for a sketch by
L.F. Ball from 1948 Dec 17. The clefts or rimae are outside
the crater to the W and NW. The original observer used a 10"
scope. Please send any images 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
