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

Ukert: a "V" on the Moon - this is a Clair-Obscur effect.
Clair-Obscur have no scientific importance and are just tricks of the
light that make us think we see something like a letter of the alphabet
or a shape or face. Clair-Obscur effects are scientifically pointless
to observe. However, if you want to be thrilled, or obtain an image to
impress someone then give them a go. If you do observe, or image this,
by all means send your observation into ALPO or the BAA, but we
probably won't publish, but will nevertheless retain in our archives,
just in case features elsewhere in the image are of interest to
future researchers.

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 .
Plato's Hook: a hook like effect in one of the shadow spires in Plato,
near a rim - this is a Clair-Obscur effect. It was first seen by
H.P.Wilkins in 1952. Clair-Obscur have no scientific importance and
are just tricks of the light that make us think we see something
like a letter of the alphabet or a shape or face. Clair-Obscur
effects are scientifically pointless to observe. However, if you want

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:

Apollo 15: This is what the lunar surface would have looked like when
Apollo 15 blasted off from the Moon. Aim for the area
of Rima Hadley. The illumination and the shadows are
exactly the same. There is no scientific value in imaging
this, but from the nostalgic point of view it might be interesting
to observe. Feel free to send your observation in to the BAA or
ALPO and we will put it in our archives, but as we have
a lot of these images already, we may not publish it, unless it is
exceptionally high in resolution. Minimum diameter scope to use
would be 20cm, but larger apertures are preferred:
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 .
BAA Request: Cavendish E - we are attempting to check out two
reports made on 2021 Jun 22 UT 20:44 and 2025 Sep 04 UT 20:04
which both said that part of the northern rim of this crater
was as bright as Aristarchus. Visual observation or images
- high resolution and/or wide angle (to compare with other
bright features) would be welcome. Telescopes of aperture 5",
or larger, should be used. Please send any 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. 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
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: In 1991 Dec 23 Bob Mizon (BAA) sketched the
crater Cleomedes and Mare Cisrium. In the floor of the shadow
filled Cleomedes was an dusky oval area - presumably the last
rays of the Sun reaching the floor. We would like yuo to
either sketch, or image, over time, how the shape of this oval
area changes, and eventually vanishes. How late in terms of
colongitude can it still be seen? Is there any hint of colour
present? Telescopes of aperture 6 inche or larger should be
used. Please send any observation
you make 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:
