ALPO Request: please image or sketch the area to the east and
north west of this group of mountains. We are attempting to
study some wrinkle ridges here, and in particular trying to
see if there is a very low lying (previously unknown) valley
in the mare here. Any visual descriptions, sketches or images
of Earthshine should be emailed to:

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 be very
careful around sunrise so as not to be observing once the Sun
has risen. Do not bother observing if the sky conditions are
hazy. Any images should be emailed to:

ALPO Request: The aim here is simply to see at what earliest
colongitude can you record with a colour camera, natural blue
color on the crater during sunrise. The effect can be quite
impressive. Try to get the exposure right else the crater will
be saturated white and you will not capture any colour. Please
send your images to: a t c @ a b e r . a c . u k

ALPO Request: On 2010 Apr 20 Ivan Bryukhanov observed an
orange-brown tint a little to the west of Zollner and Kant
craters. A refractor would be suitable for this, although any
sized scope larger than 4.5" aperture would suffice. Its
possible that this might have been related to the low
altitude of the Moon, therefore observing with the Moon down to
about 15-5deg above the horizon is acceptable for this to see if
we can replicate colour here. Please send any images, detailed
sketches, or visual descriptions to: a t c @ a b e r . a c. u k
BAA Request: Please image t or sketch this area, looking
especially for two bright points of light on the edge of the
termiator. A scope of at least 4" aperture is needed for this
observation. All images or sketches should be emailed to:
a t c @ a b e r . a c. u k
BAA Request: Some astronomers have occasionally reported seeing
a pseudo peak on the floor of this crater. However there is no
central peak! Please therefore image or sketch the floor,
looking for anything near the centre of the crater resembling
a light spot, or some highland emerging from the shadow. All
reports should be emailed to: a t c @ a b e r . a c . u k
BAA Request: Monitor the central peak for brightness changes. Do
they change with atmospheric seeing conditions? Any brightness
measurements or image sequences made should be emailed to:
a t c @ a b e r . a c . u k
BAA Request: On 2010 Apr 27 Peter Grego noticed a craterlet
just to the east of Briggs (this is normal), but also an E-W
trending lineament or wrinkle ridge that does not show up on
NASA LAC charts - it is this we wish to confirm by re-
observing under similar seleonographic colongitudes. An 8" or
larger telecope is required, Please send any high resolution
images, detailed sketches, or visual descriptions to:
a t c @ a b e r . a c. u k .
ALPO Request: Please take images of the Full Moon, but make
sure you under expose as we want to avoid bright ray craters
like Aristarchus, Tycho, Proclus etc from saturating. The
purpose behind this is we want to compare with images of
Earthshine which are essentially zero phase illumination
images, like at Full Moon. There have been reports in the past
that Aristarchus varies greatly in brightness compared to
other features. David Darling (a past TLP coordinator) has
suggested this was simply due to libration effects, i.e.
viewing angles, so we would naturally like to test this
theory out. Also if you have any past images of close to Full
Moon, please send these in too if the above mentioned craters
are not saturated. Pretty much any size telescope can be used
to take these images so long as we can clearly see the above
craters. Obviously do not attempt this if the sky is cloudy or
hazy. Observations will be presented in the "Lunar Observer"
- a monthly publication of the Lunar Section of ALPO. All
reports should be emailed to:
a t c @ a b e r . a c . uk
BAA Request: Do the appearance of the bands on the crater rim
vary (blur) in appearance over time? Compare them to bands in
other craters e.g. Herodotus, Kepler, Copernicus. If you do
see any variations in sharpness, see how it relates to
atmospheric seeing condtions. All images or sketches should
be emailed to:
