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: On 1989 Feb 17 David Darling made an observation
about the brightness of the east and west walls of Proclus. We
would like you to image, sketch, or just visually note which
is brighter, the east or the west rim of this crater?
Telescopes of aperture 6 inche or larger should be used.
Please send any observation you make to:

BAA Request: Look for colour along the edge od the SW ray
between Aristarchus and Herodotus. Mimimu sized telescope
diameter 8". Try to use a magnification of between 100 and 200x.
Use red, blue filters to verify colour e.g. Wratten 25 and
Wratten 44a. Otherwise use colour imaging - but keep the
exposure short enough to avoid saturating Aristarchus or the SW
ray. Any sketches or colour images should be emailed to:
a t c @ a b e r . a c . u k
ALPO Request: Can you see a darkening on the northen floor of
this crater? All visual reports, sketches or color images should
be emailed to:

BAA Request: Mare Humboldtianum. We are trying to replicate,
using modern day images, a sketch in Plate I in BAA The Moon
from published: 1950 Jun Vol 1, No. 1. Its for a sketch by
K.W. Aboneri from 1949 Sep 7. Please send any images 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: 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 .
BAA Request: Compare the brightness of Tycho with Cassini and
a bright spot in Delandres. Use red and violet filters.
Telescopes of apertures as small as 2.5" can be used for this
study (if possible a refractor) with a magnifiaction of
around x50. Colour imagery can also be used providing that
the exposure is short enough to avoid saturation on bright
features. Any visual descriptions, sketches or images 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: Colour imagery or visual skecthes needed of this
crater. Can you see or detect any colour on the rim? If
imaging, make sure you do not over expose the rim. Use a
reflector or SCT telescope. Minimum aperture allowed: 6". All
images should be sent to me on the email adrress below,
whether or not you were successful in capturing the central
peak: a t c @ a b e r . a c. u k
