BAA Request: Please try to image the Moon as a very thin
crescent, tryimg to detect Earthshine. A good telephoto lens
will do on a DSLR, or a camera on a small scope. We are
attempting to monitor the brightness of the edge of the
earthshine limb in order to follow up a project suggested by
Dr Martin Hoffmann at the 2017 EPSC Conference in Riga,
Latvia. This is quite a challenging project due to the sky
brightness and the low altitude of the Moon. Please do not
attempt if the Sun is still above the horizon. Do not bother
observing if the sky conditions are hazy. Any 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 morning, that it
starts to show 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
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:

BAA Request: Images and skecthes needed of this feature. Use
a telescope of at least 6" aperture and a magnification of
300-350x. Any sketches, visual descriptions, or images taken,
should be emailed to:

BAA Request: Images or sketches of this crater needed. We are
trying to see if a curious gray band is visible across the
crater floor as seen by T. Smith on 2020 Nov 22. Any sized
scope can be used from 5" or upwards. All images should be
sent to: a t c @ a b e r . a c . u k
BAA Request: Eudoxus - please try to image the interior of
this crater. We are trying to detect bright spots and a linear
features within the shadow of the east wall at sunrise. Nigel
Longshaw (BAA) suspects that this might explain Trouvelot's
obsevation in 1877 of a luminous rope-like feature.
Please send any images to: a t c @ a b e r . a c. u k .
BAA Request: Eudoxus - please try to image or skecth the
crater. This is to try to explain a line of light effect seen
inside this crater by French astronomer Trouvelot back in
Victorian times. The BAAs Nigel Longshaw says that this may be
seen between colongitudes of 0.3 to 1.2 degrees. Please send
any images or sketches to: a t c @ a b e r . a c. u k .
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:
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:
