Ill is percentage illumination of the Moon


2018-Apr-01 UT 00:00-07:41 Ill=99% Full_Moon

     ALPO Request: Please take images of the Full Moon, but make 
     sure you under expose as we want to avoid bright ray craters 
     like Aristarchus, Tycho, Proclus etc from saturating. The 
     purpose behind this is we want to compare with images of 
     Earthshine which are essentially zero phase illumination 
     images, like at Full Moon. There have been reports in the past 
     that Aristarchus varies greatly in brightness compared to 
     other features. David Darling (a past TLP coordinator) has 
     suggested this was simply due to libration effects, i.e. 
     viewing angles, so we would naturally like to test this 
     theory out. Also if you have any past images of close to Full 
     Moon, please send these in too if the above mentioned craters 
     are not saturated. Pretty much any size telescope can be used 
     to take these images so long as we can clearly see the above 
     craters. Obviously do not attempt this if the sky is cloudy or 
     hazy. Observations will be presented in the "Lunar Observer" 
     - a monthly publication of the Lunar Section of ALPO. All 
     reports should be emailed to: 
     a t c @ a b e r . a c . uk


2018-Apr-01 UT 03:36-05:45 Ill=99% Aristarchus

     BAA Request: Please compare the brightness of Aristarchus 
     with Proclus, Censorinus, or any other similar sized bright 
     crater, over time e.g. every 5 or 10 min. Can you see any 
     changes in brightness? If so which crater is the one that is 
     varying Apertures as small as 2" diameter can be used for 
     this work, so long as the magnification is of the order of 
     100x. Please send all brightness meaurements or image 
     sequences to: 
     a t c @ a b e r . a c. u k 


2018-Apr-07 UT 08:11-08:30 Ill=59% Aristarchus

     BAA Request: please study visually or image this crater, 
     concentrating especially on the east rim and beyond. Is there 
     a bright spot on the east rim, and how does it compare in 
     brightness to the central peak of Aristarchus. oes the 
     apparance change over time? Also is there anything just beyond 
     the eastern rim which might resemble a crater rim? Any visual 
     descriptions, sketches or images of Earthshine should be 
     emailed to: a t c @ a b e r . a c . u k


2018-Apr-08 UT 06:55-08:06 Ill=50% Earthshine: sporadic meteors

     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.

     Montes Teneriffe in the viciniity of Pico B, Plato E and D. 
     The UAI are interested in confirming a suspected volcanic 
     dome-like structure in this area, observed by Maurizio 
     ecchini, a member of the UAI Lunar Section. Scopes of 4" 
     diameter, or preferably larger, should be used. Any sketches

2018-Apr-14 UT 06:57-08:11 Ill=4% Moon

     BAA Request: Please try to image the Moon as a very thin 
     crescent, tryimg to detect Earthshine. A good telephoto lens 
     will do on a DSLR, or a camera on a small scope. We are 
     attempting to monitor the brightness of the edge of the 
     earthshine limb in order to follow up a project suggested by 
     Dr Martin Hoffmann at the 2017 EPSC Conference in Riga, 
     Latvia. This is quite a challenging project due to the sky 
     brightness and the low altitude of the Moon. Please be very 
     careful around sunrise so as not to be observing once the Sun 
     has risen. Do not bother observing if the sky conditions are 
     hazy. Any images should be emailed to: 
     a t c @ a b e r . a c . u k


2018-Apr-16 UT 20:16-21:18 Ill=1% Moon

     BAA Request: Please try to image the Moon as a very thin

     attempt if the Sun is still above the horizon. Do not bother 
     observing if the sky conditions are hazy. Any images 
     should be emailed to:

2018-Apr-18 UT 20:00-20:01 Ill=9% Picard

     BAA Request: On 2013 Feb 17 UAI observer: Giuseppe Macalli 
     observed visually an orange cloud form just to the west of 
     Picard crater, and then dissappear. The effect lasted about 1 
     minute. Obviously we are not likely to see whatever this was 
     (?) again under similar illumination, but just for the record 
     it would be useful to have a high resolution monochrome or 
     colour image of this area, at the requested observing 
     time.Please send any high resolution images to: 
     a t c @ a b e r . a c. u k .

2018-Apr-21 UT 21:48-22:46 Ill=38% Proclus

     ALPO Request: Minimum aperture scope to be used 6" (a refractor 
     if possible) and at a magbification of approximately 300x. How 
     does the crater compare in red and blue light i.e. Wratter 25 
     and 38A filters? Also the three shadow patches in the crater, 
     which one is the darkest? Can you see running along the SW edge 
     of the crater floor, a hill - to the north of which is a less 
     elevated plateau? As the observing period progresses, do you see 
     the brilliantly illuminated north crater wall develope a darker 
     area which gradually becomes more prominent, despite the Sun 
     getting higher in altitude above the lumnar surface? Sketch or 
     images sequences welcome here and should be emailed to:

2018-Apr-23 UT 20:09-21:46 Ill=61% Montes_Teneriffe

     BAA Request: please image this area as we want to compare 
     against a sketch made in 1854 under similar illumination. 
     However if you want to check this area visually (or with a 
     colour camera) we would be very interested to see if you can 
     detect some colour on the illuminated peaks of this mountain 
     range, or elsewhere in Mare Imbrium. Features to capture in 
     any image (mosaic), apart from Montes Teneriffe, should 
     include: Plato, Vallis Alpes, Mons Pico and Mons Piton. Any 
     visual descriptions, sketches or images of Earthshine should 
     be emailed to: a t c @ a b e r . a c . u k


2018-Apr-23 UT 21:12-21:46 Ill=61% Plato

     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 .


2018-Apr-24 UT 01:08-01:40 Ill=62% Tycho

     BAA Request: How early can you see the central peak of this 
     crater illuminated by scattered light off the crater's west 
     illuminated rim? High resolution and/or long exposures needed 
     to capture detail inside the floor shadow. All images should 
     be sent to me on the email adrress below, whether or not you 
     were successful in capturing the central peak: 
     a t c @ a b e r . a c. u k 


2018-Apr-24 UT 20:31-20:48 Ill=72% Copernicus

     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 .


2018-Apr-24 UT 22:47-01:55 Ill=72% Cichus

     BAA Request: Following an article by Nigel Longshaw in the 
     Journal of the British Astronomical Association in 2015 June 
     (p154-157), we would like to encourage sketches and images of 
     the Cichus-Weiss region of the Moon. At this particular 
     illumination you may be able to see (depending upon libration) 
     a "curved thread of light" effect extending into the night 
     side of the Moon, just north of Cichus. The effect was 
     originally detailed by Thomas Elger in a sketch from 1888. We 
     would very much like to know the duration of this effect. 
     Ideally suited for scopes of aperture 4" or larger. If 
     imaging, try over exposing slightly in order to bring ut 
     detail on the terminator. Please send any observation 
     you make to: 
     n i g e l @ a j c o c k e r a s s o c i a t e s . c o . u k


2018-Apr-26 UT 00:47-01:45 Ill=82% Ramsden

     BAA Request: Monitor the brightness of the bright spot on the 
     west wall over time. Minimum sized aperture scope needed: 4". 
     Any visual brightness measurements or image time sequences 
     should be emailed to: 
     a t c @ a b e r . a c . u k


2018-Apr-26 UT 21:40-04:10 Ill=89% Aristarchus

     BAA Request: Is there a bright spot on the west interior wall of 
     this crater? Compare it to other features and note if it varies 
     in brightness over time. Please send all reports or images to: 
     a t c @ a b e r . a c. u k 


2018-Apr-26 UT 23:09-00:06 Ill=89% Aristarchus

     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 .


2018-Apr-26 UT 23:39-01:12 Ill=89% Torricelli_B

     BAA Request: How dull is the crater? Compare to other similar sized features. Is there a halo aroun     d the crater and what 
     size is it (using the crater diameter as a reference), and 
     also does it have any colour? Look for any variability in the 
     crater brightness and the visibolity of the halo? How are 
     these affected by seeing conditions? Minimum aperture 
     requirements 15cm. All observations should be emailed to: 
     a t c @ a b e r . a c. u k .


2018-Apr-27 UT 03:11-03:58 Ill=90% Torricelli_B

     ALPO Request: How dull is the crater? Compare to other similar 
     sized features. Is there any variability in brightness with 
     atmospheric conditions e.g. haze or seeing? Minimum aperture 
     requirements 15cm. All observations (especially images) should 
     be emailed to: a t c @ a b e r . a c. u k .


2018-Apr-27 UT 03:59-04:00 Ill=90% Mersenius_C

     ALPO Request: Color images or visual inspection needed of the 
     area just SW of this crater. If taking images, do not over 
     expose on bright slopes. Can you detect any natural surface 
     color here or mistiness? Minimum aperture needed 4", and if you 
     have a choice, use a refractor instead of a reflector. Please 
     send any images, or sketches, to: a t c @ a b e r . a c. u k
