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
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.
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 UAI - email: a m . 5 4 8 5 2 @ g m a i l . c o m

BAA Request: Please image 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: Can you see any sign of "greyness" inside the shadow on the floor of Tycho? This is possibly due to scattered light off of the illuminated walls of Tycho. Mimimum sized aperture telescope to use should be an 8" reflector. Any visual descriptions, sketches or slightly over exposed images should be emailed to: a t c @ a b e r . a c. u k
"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.

BAA Request: Two observers have reported colour on the rim around this colongitude, once in 1938, and again in 2013. Please take a look and report what you see, and where on the rim. Please send any high resolution images, detailed sketches, or visual descriptions to: a t c @ a b e r . a c. u k .
BAA Request: Tycho. We are trying to replicate, using modern day images, a sketch in Plate X in BAA The Moon from published: 1950 Jun Vol 1, No. 1. It is for a sketch made by H.P. Wilkins from 1949 Jun 05. The original sketch was made with an 12" telescope. Please send any images to: a t c @ a b e r . a c. u k .
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
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: It has been noticed that a bright carterlet can appear very suddenly on the floor of Plato in between needle like shadows, during local lunar sunrise. This happens in the space of just a minute or so, and can look really quite dramatic. This effect was first spotted by Brian Halls on 2014 Oct 31 Please send any high resolution images, detailed scetches, or visual descriptions to: a t c @ a b e r . a c. u k .
