ALPO Request: Can you resolve any details inside Picard tonight?
Is it surrounded by a nebulous patch? We are just checking up on
the normal appearance of this crater and its surrounds, to
verify an observational report from 1994 during the ALPO
Clementine watch. Use a telescope of aperture 6 inches or
larger. All sketches or monochrome 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
"Jewelled Handle": in Montes Jura - this is a Clair-Obscur effect. Its
an illuminated arc. 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: 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: 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:

Face of Albategnius: you can see the profile of a face in a shadow
from the eastern edge of this crater - this is a Clair-Obscur effect.

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

Monte Caucasus: "shadow face" silhouette Clair-Obscur effect.
Clair-Obscur effects have no scientific importance 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 useless to observe. However, if
you want to be thrilled, or obtain an image to impress someone
then give them a go. This effect on the southern end of Montes
Caucuses looks like the side silhouette of a cartoon human face.
We are still slightly undertain about the precise colongitude
range, so if you do not see the face, try again later. 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.
Note that we have some uncertainty in the colongitude range
- so if you don't see it, please tells us the date and UT so
we can make some improvements in the predictions.
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
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,

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:

ALPO Request: This request comes about because of two
observations. Firstly on 2009 Nov 25 Paul Abel and others
detected some colour on the inner west illumntated slopes of
this crater. No similar colour existed elsewhere. On 2012 Aug
25 Charles Galdies imaged this crater and detected a similar
colour, approximately in the same location, though he also
imaged colour elsewhere. It is important to replicate this
observation to see if it was natural surface colour,
atmospheric spectral dispersion, or some effect in the camera
that Charles was using, namely a Philips SPC 900NC camera.
The minimum sized telescope to be used would ideally a 8"
reflector. Please send any high resolution images, detailed
sketches, or visual descriptions to:

Eyes of Clavius: you can see this crater with two eyes, Clavius C and
Clavius D - 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.
