ALPO Request: Can you see a darkening on the northen floor of this crater? All visual reports, sketches or color images should be emailed 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
BAA Request: In 1991 Dec 23 Bob Mizon (BAA) sketched the crater Cleomedes and Mare Cisrium. In the floor of the shadow filled Cleomedes was an dusky oval area - presumably the last rays of the Sun reaching the floor. We would like yuo to either sketch, or image, over time, how the shape of this oval area changes, and eventually vanishes. How late in terms of colongitude can it still be seen? Is there any hint of colour present? Telescopes of aperture 6 inche or larger should be used. Please send any observation you make to: a t c @ a b e r . a c . u k
BAA Request: Sketches or images needed of Toricelli B - of sufficient resolution to reveal shadow. All observations, including sketches or images shouild 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: Try viewing the central peak through a red and blue filter e.g. Wratten 25a and 38, and comparing the brightness to the of the eastern sunlit rim. Does the size of the central peak change between filters? If you do detect colour here, obviously check for colour on other central peaks. If taking colour images, make sure that you do nderexpose slightly so as to avoid saturating the central peak. All visual reports, sketches or colour images should be emailed 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
