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: 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. 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.

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
ALPO Request: Please examine the crater through red and blue filters e.g. Wratten 25 and 38A. Can y ou see both the NE and SE walls in the blue filter? Which is the brightest of the two walls and what does it best compare in brightness to elsewhere on the Moon? Can you see a thread like strip along the NW wall? How dark is the interior shadow and can you see a thread of light effect in this that was parallel to the illumnated eastern wall? The minimum sized telescope to use would by 6" aperture or larger (prefrably a refractor if you have one). Please send any detailed sketches or high resolution images to: t o n y . c o o k @ a l p o - a s t r o n o m y . o r g
