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:

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:
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
BAA Request: On 2013 Aug 26 Peter Grego observed a dark patch
just east of Jansen D. He had not seen this before, therefore it
is important to repeat this observation under simuilar
illumination conditions. It maybe a buried crater? Ideally
suited to scopes of aperture 8" or larger. Please send
any high resolution images, detailed scetches, or
visual descriptions to: a t c @ a b e r . a c. u k .
ALPO Request: Fracatorius - please try to image / sketch /
visually observe the interior shadowed floor of the crater on
the sunset terminator. Can you detect a central bright spot in
the dark dhadow filled floor of the crater? How does its
appearance change over time? Minimum aperture scope to use
9cm. Please send any images to: a t c @ a b e r . a c. u k .
BAA Request: On 2011 Jan 21 Nigel Longshaw suspected the
eastern side of Geminus (on the border of the crater filled
shadow and the eastern illuminated rim) had a colouration to
it. This extended for a short distance from the floor shadow
into the illuminated rim width and spanned from the north to
the south of the crater. For a comparison, Cleomedes was
checked but nothing unusual was noticed in its shadow. The
observer notes that Elger also saw colour here too. Its
probable that some natural surface colouration was observed,
but this needs to be checked out? Telescopes of aperture 4"
or larger are needed to observe this effect. If you have a
refractor, then try using this, otherwise a reflector will do
just as well. Please send any sketches, images, or visual
descriptions to: a t c @ a b e r . a c. u k .

Yerkes: a "Woodpecker" shaped shadow - 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. This particular Clair-Obscur effect was first
reported by KC Pau.

BAA Request: Can you see, or image, 4 points of light in the
shadowed floor of the crater? How do these change in
appearance over time? This is not a TLP but is still
interesting to observe as it might look like a string of
pearls effect. Please send any images, or sketches, to:

ALPO Request: On 2011 Dec 31 Raffaello Braga found the north rim
or Torricelli to be very bright at the start of the observing
session but dimmed considerably later. He was not sure on the
normal appearance of this crater, hence why it is really
imortant to establish this by re-observing under similar
illumination. Minimum telescope aperture required: 3", and try
to use a refractor if possible. Please send any high resolution
images, detailed scetches, or visual descriptions 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.
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,

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.

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

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:

BAA Request: Aristarchus area - We are trying to explain an
observation from Meudon Observatory in France made in 1881 of
a bright rope-like effect seen in the vicinity of this crater.
Please send any images 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
