BAA Request: It has been noticed that a bright carterlet can
appear very suddenly on the floor of Plato in between needle
like shadows, during local lunar sunrise. This happens in the
space of just a minute or so, and can look really quite dramatic.
This effect was first spotted by Brian Halls on 2014 Oct 31
Please send any high resolution images, detailed scetches, or
visual descriptions to: a t c @ a b e r . a c. u k .
UAI Request: Franco Taccogna (UAI) would like to know at what
colongitude range does this feature start to brighten up
dramatically. Please send in any images taken with a telescope
size of at least 6 inches to:

BAA Request: On 2012 Sep 24 E. Horner noticed a very strong red
colour around part of the sunlit inner rim of Copernicus,
sometimes a 1/4 and sometimes 1/2 around the interior. Quite
likely this was some form of atmospheric spectral dispersion -
though the observer checked for similar effects on other craters
but saw none. But to be sure we would like to obtain some colour
images or visual observations of this crater. The minimum sized
telescope to be used would ideally a 6" reflector. Low elevation
angles for the Moon are ideal as we want to try to replicate
this effect if it is indeed due to atmospheric spectral
dispersion. Please send any high resolution images, detailed
sketches, or visual descriptions
to: a t c @ a b e r . a c. u k .
ALPO Request: Compare the darkness of the floor in red and
blue filters e.g. (Wratten 25 and 44a). All visual reports,
sketches or colour images should be emailed to:

ALPO Request: On 2013 Apr 22 Paul Zellor noticed that the two
closely spaced NW dark bands in Aristarchus had some (non-blue)
color to them. Can we confirm his observation of natural colour
here? Ideally you should be using a telescope of 10" aperture, or
larger. Please send any high resolution color images, detailed
sketches, or visual descriptions 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.

ALPO Request: Please take images of the Full Moon, but make
sure you under expose as we want to avoid bright ray craters
like Aristarchus, Tycho, Proclus etc from saturating. The
purpose behind this is we want to compare with images of
Earthshine which are essentially zero phase illumination
images, like at Full Moon. There have been reports in the past
that Aristarchus varies greatly in brightness compared to
other features. David Darling (a past TLP coordinator) has
suggested this was simply due to libration effects, i.e.
viewing angles, so we would naturally like to test this
theory out. Also if you have any past images of close to Full
Moon, please send these in too if the above mentioned craters
are not saturated. Pretty much any size telescope can be used
to take these images so long as we can clearly see the above
craters. Obviously do not attempt this if the sky is cloudy or
hazy. Observations will be presented in the "Lunar Observer"
- a monthly publication of the Lunar Section of ALPO. All
reports should be emailed to:
a t c @ a b e r . a c . uk
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: Sketches or images needed of Toricelli B - of
sufficient resolution to reveal shadow. All observations,
including sketches or images shouild 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 .
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:

ALPO Request: Please monitor the area of shadow east of the
central peak of Tycho. We are trying to see of a neckless V
shaped formation occurs and how it forms over time as the Sun
rises. Both visual and CCD imaging would be useful and people
with scopes larger than than 6" aperture shouild be used. Any
sketches or images should be emailed to:
