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: a t c @ a b e r . a c . u k

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: a t c @ a b e r . a c . u k

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: a t c @ a b e r . a c. u k
