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: Either visually observe or obtain a colour image
of this crater shortly after it has emerged from the sunrise
terminator. Minimum sized aperture scope needed: 5". Any
observations or images should be emailed to:
a t c @ a b e r . a c . u k
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: 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 .
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:
ALPO - email: c u d n i k @ s b c g l o b a l . n e t
BAA - email: a t c @ a b e r . a c . u k

Tycho: "V-shaped pearl neckless" effect - 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. This effect was first spotted by
David Darling in 1992 Aug 21 and was considered to be a possible TLP
until the effect was seen repeated at similar illumination. 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.

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.
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:

Apollo 14: This is what the lunar surface would have looked like
when Apollo 14 touched down on the Moon. Aim for the area
north of Fra Mauro. 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:
Apollo 12: This is what the lunar surface would have looked like
when Apollo 12 touched down on the Moon. Aim for the area
SW of Lansberg. 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

"Jewelled Handle": in Montes Jura - this is a Clair-Obscur effect. Its
an illuminated arc. Clair-Obscur have no scientific importance and are

scientifically pointless to observe. However, if you want to be
