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
BAA Request: On 2012 Sep 24 E. Horner noticed a very strong red colour around part of the sunlit inner rim of Copernicus, sometimes a 1/4 and sometimes 1/2 around the interior. Quite likely this was some form of atmospheric spectral dispersion - though the observer checked for similar effects on other craters but saw none. But to be sure we would like to obtain some colour images or visual observations of this crater. The minimum sized telescope to be used would ideally a 6" reflector. Low elevation angles for the Moon are ideal as we want to try to replicate this effect if it is indeed due to atmospheric spectral dispersion. 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: Any colour visible on the northern edge? Check with filters if you are observing visually. Otherwise use colour imaging.Please use a telescope of aperture 20cm or larger. Any visual descriptions, sketches, or 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: Take high resolution images of the area north of Descartes to capture a view of what the lunar surface would have looked like from Earth at the moment Apollo 16 lifted off of the Moon. Minimum diameter scope 20cm, larger apertures preferred: a t c @ a b e r . a c . u k
ALPO Request: On 2013 Apr 22 Paul Zellor noticed that the two closely spaced NW dark bands in Aristarchus had some (non-blue) color to them. Can we confirm his observation of natural colour here? Ideally you should be using a telescope of 10" aperture, or larger. Please send any high resolution color images, detailed sketches, or visual descriptions to: a t c @ a b e r . a c. u k .
ALPO Request: Compare the crater in red and blue light - if possible use Wratten 25 and Wratten 38A filters. If its brighter in one filter than the other, is this because one filter is a lot darker than the other, or is the effect confined only to this crater? Any visual descriptions, 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
ALPO Request: Please supply images, or sketches, of this area, especially covering the area to the east. Any size scope can be used for this study. All observations should be emailed 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: 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
BAA Request: On 2013 Aug 26 Peter Grego observed a dark patch just east of Jansen D. He had not seen this before, therefore it is important to repeat this observation under simuilar illumination conditions. It maybe a buried crater? Ideally suited to scopes of aperture 8" or larger. Please send any high resolution images, detailed scetches, or visual descriptions to: a t c @ a b e r . a c. u k .

ALPO Request: On 2013 Sep 01 a lunar astrophotographer, Maximilian Teodorescu, imaged a dark dusky cicular area to the SE of Hermann D. The odd thing is that simulations show that there should not be a circular low lying depression here. It maybe a dust ring on his camera, but it did feature in the Lunar Picture of the nDay (LPO) web site on 2013 Sep 13.

ALPO Request: On 2012 Feb 28 Raffaello Braga noted that only the tip of the central peak was visible. Most of the crater was in darkness - this was normal at this stage in illumination. When viewed through a red filter, the central peak was visble, but however when viewed through a blue filter it was invisible. Please try to observe this crater visually with red and blue filters, to see if you can replicate this effect? If so then check for similar effects on other craters on the terminator. Otherwise try to obtain some high resolution colour images. This work is suitable for telescopes of 4" aperture or larger - if you have a choice of a efractor or a reflector, please try the refractor. Please send any observations you make to: a t c @ a b e r . a c . u k
BAA Request: On 1972 May 18 M.Burton (UK) saw a E-W light streak across the floor of this crater and also that the east side of the crater was very billiant. This is probably a normal appearance for this stage in illumination, but we would like to check this out. Minimum sized telescope to use is a 5". 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: On 2011 Dec 31 Raffaello Braga found the north rim or Torricelli to be very bright at the start of the observing session but dimmed considerably later. He was not sure on the normal appearance of this crater, hence why it is really imortant to establish this by re-observing under similar illumination. Minimum telescope aperture required: 3", and try to use a refractor if possible. Please send any high resolution images, detailed scetches, or visual descriptions to: a t c @ a b e r . a c. u k .
