BAA Request: On 2013 Feb 17 UAI observer: Giuseppe Macalli
observed visually an orange cloud form just to the west of
Picard crater, and then dissappear. The effect lasted about 1
minute. Obviously we are not likely to see whatever this was
(?) again under similar illumination, but just for the record
it would be useful to have a high resolution monochrome or
colour image of this area, at the requested observing
time.N.B. an image in the 2018 Jun LSC suggests that the date
given of 2013 Feb 17 may have been Feb 18? Please send any
high resolution images to: a t c @ a b e r . a c. u k .
ALPO Request: Compare the crater in red and blue light - if
possible use Wratten 25 and Wratten 38A filters. Please
use a telescope of aperture 6 or larger (refractor if
possible) and at appromimately x250. Any visual descriptions,
sketches, or colour images should be emailed to:

BAA Request: Examine the floor visually, sketch, or image to
show the progression of the shadow spires across floor. If
observing visually, how would you describe the appearance of
the central lit area on the floor? If imaging, do a time lapse
e.g. 1 image per minute to show the progression of the shadow
spires. We are asking for these observations following an
observation by N. Travnok (Brazil) on 2020 Jul 27 UT 23:00 who
commented on an unusual appearance to the floor. It would be
really useful to have visual observing of the appearance and
please note down what the seeing conditions are like. If you
want to image it at high resolution, please go ahead but
remember that any image stacking should not be from sections
of video of longer than 1 min duration as the shadows change
in length rather quickly at sunrise. Any sketches, visual
descriptions, or images taken, should be emailed to:

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 .
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:

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 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 .
ALPO Request: Images needed of this part of the Moon. Can be
taken with small telescopes - we just need to compare some of
the ray areas to an image taken during a lunar eclipse. All
images should be emailed
to:
