"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: 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
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.
