ALPO Request: Try viewing the central peak through a red and
blue filter e.g. Wratten 25a and 38, and comparing the
brightness to the of the eastern sunlit rim. Does the size
of the central peak change between filters? If you do detect
colour here, obviously check for colour on other central
peaks. If taking colour images, make sure that you do
nderexpose slightly so as to avoid saturating the central
peak. All visual reports, sketches or colour images should be
emailed to:

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: Take high resolution images of the area just
north of Fra Mauro to capture a view of what the lunar surface
would have looked like from Earth at the moment Apollo 14
lifted off of the Moon. Minimum diameter scope 20cm, larger
apertures preferred:

ALPO/BAA request - in 1965 May 12 UT 19:10 the Soviet Lunar 5
probe crashed into the Moon (by accident). There are reports
of an ejecta cloud, though strangley three locations are
given, two of which are based upon telescope observations at
the time. We would like you to image the surface of the Moon
in the vicinity of these three craters: Copernicus, Deslandres
and Lansberg, so that we can compare to photographs which were
supposed to show the ejecta cloud back in 1965. Please email
any images to: a t c @ a b e r . a c . u k
ALPO Request: Monitor this crater over time to see if there
are any brightness changes inside. A minimum sized scope to
use for this would be an 8" reflector. Any visual
descriptions, sketches, or colour images should be emailed
to:

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: 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 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 .
