BAA Request: Take high resolution images of the area to the
north of Moltke to capture a view of what the lunar surface
would have looked like from Earth at the moment Apollo 11
touched down on the Moon. Minimum diameter scope 20cm, larger
apertures preferred:

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: Lassell - we are trying to compare a sketch made
by T.G. Elger (1883 Jan 13 UT 19:40), that appeared on the
front cover of the BAA's The Moon publication from 1956 Vol 5
No. 2, to what can be captured with modern day imagery. This
is a good way to compare and contrast observations made by eye
with CCD imagery.Telescopes of aperture 8", or larger, should
be used. Please send any images 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:
a t c @ a b e r . a c. u k
BAA Request: Please can you verify that the central peak of
this crater is difficult to disern, and that the floors of
both Campanus and Mercator are generally devoid of detail.
Telescopes no smaller than 6" aperture should be used with
magnifications of approximately x180 for visual observations.
Images or sketches are welcome too. The purpose of this
request is to verify a description of the craters made by SPA
observer Steve Bush on 2014 Jan 31 IT 22:00-22:30.
Observational reports should be emailed 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: Can you detect any colour, inside the crater, on
the floor and elsewhere? Can you image any colour? Minimum
telescope aperture needed: 6", and if possible try using a
refractor. All images or sketches should be sent
to me on this email adrress: a t c @ a b e r . a c. u k
ALPO Request: Take a look at the bright area on the crater
floor, and the bright east facing part of the western rim, in
red and blue light e.g. Wratten 25 and 38A. Do these look
brighter to you in red or blue light? If you have these filters,
is it the fact that the Wratten 38A filter, being denser, makes
these areas brighter in one filter than in the other? Test them
out on other features. Any visual descriptions, sketches or
colour images should be emailed to:
t o n y . c o o k @ a l p o - a s t r o n o m y . o r g
ALPO Request: Compare the crater in red and blue light - if
possible use Wratten 25 and Wratten 38A filters. If its
brighter in one filter than the other, is this because one
filter is a lot darker than the other, or is the effect
confined only to this crater? Any visual descriptions,
sketches, or colour images should be emailed to:
t o n y . c o o k @ a l p o - a s t r o n o m y . o r g
BAA Request: please image/sketch this area as we want to
compare against an image made by K. Kilburn on 2019 Sep 13
which shows a bright coloured spot here. Please use an
aperture of at least 80 mm and if imaging use a one-shot
colour camera such as a DSLR or web cam. Please take a time
sequence or monitor the area visually for colour or
brighenings. Pay sepcial attention to how atmospheric seeing
conditions affect the brightness/apearance of this crater. Any
visual descriptions, sketches or images 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
ALPO Request: What we are interested in here is time sequences
sketches or images of the central peak and shadowed interior
of the floor of this crater. Can you see any detail inside the
shadow? Is the shadow completely black in colour or is there
some greyness? How does the brightness of the central peak
change over time? All visual reports, sketches or colour
images should be emailed to:
