Ill is percentage illumination of the Moon


2020-May-04 UT 19:31-20:44 Ill=90% Herodotus

     BAA Request: Some astronomers have occasionally reported seeing 
     a pseudo peak on the floor of this crater. However there is no 
     central peak! Please therefore image or sketch the floor, 
     looking for anything near the centre of the crater resembling 
     a light spot, or some highland emerging from the shadow. All 
     reports should be emailed to: a t c @ a b e r . a c . u k 


2020-May-06 UT 22:25-23:47 Ill=100% Deluc_H

     SLA Request: Deluc H. On 2019 Oct 06 Alberto Anunziato 
     observed an rapid change in appearance (few tens of minutes) 
     in relation to west rim - presumably an illumination effect. 
     Please submit any sketches or images of this crater to me and 
     it will be passed onto the SLA. Please email these to: 
     a t c @ a b e r . a c. u k 


2020-May-07 UT 23:29-00:13 Ill=100% 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 


2020-May-23 UT 20:33-20:44 Ill=1% 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 do not 
     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: 
     a t c @ a b e r . a c . u k


2020-May-26 UT 20:47-21:13 Ill=17% 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.
     Dates/UTs of observing runs, or detections of impacts, should be emailed to:

     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.

2020-May-28 UT 21:49-22:00 Ill=36% Maurolycus

     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


2020-May-28 UT 20:50-22:34 Ill=36% 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.

2020-May-29 UT 22:45-23:31 Ill=48% Ptolemaeus

     BAA Request: Examine the floor visually, sketch, or image to 
     show the progression of the shadow spires across floor and 
     the emergence of the centre of the floor into sunlight. If 
     observing visually, how would you describe the appearance of 
     the central lit area on the floor? If imaging, do a time lapse 
     e.g. 1 image per minute to show the progression of the shadow 
     spires. We are asking for these observations following an observation by P. Shepherdson (BAA) on 20     20 Feb 01 UT 19:40-19:50 who commented on an unusual appearance to the floor. However an image supp     lied suggests it is just shadow spires. Nevertheless we would like to check at a repeat 
     illumination. As another challenge, because the light 
     illuminating the floor may come from narrow horizontal gaps on 
     the eastern rim, and maybe slightly polarized see if you can 
     use a polarized filter in the field of view at the eyepiece, 
     or in front of the camera, and rotate through different 
     angles. Do you see any change in the appearance of the 
     illuminated area of the floor? Any sketches, visual 
     descriptions, or images taken, should be emailed to: 
     a t c @ a b e r . a c. u k

2020-May-30 UT 22:49-23:59 Ill=59% Eratosthenes

     ALPO Request: This request comes about because of two 
     observations. Firstly on 2009 Nov 25 Paul Abel and others 
     detected some colour on the inner west illumntated slopes of 
     this crater. No similar colour existed elsewhere. On 2012 Aug 
     25 Charles Galdies imaged this crater and detected a similar 
     colour, approximately in the same location, though he also 
     imaged colour elsewhere. It is important to replicate this 
     observation to see if it was natural surface colour, 
     atmospheric spectral dispersion, or some effect in the camera 
     that Charles was using, namely a Philips SPC 900NC camera. 
     The minimum sized telescope to be used would ideally a 8" 
     reflector. Please send any high resolution images, detailed 
     sketches, or visual descriptions to: 
     a t c @ a b e r . a c. u k .


2020-May-31 UT 20:44-23:29 Ill=70% Mare_Frigoris

     UAI Request: Mare Frigoris between Plato and Fontenelle 
     (colongitude from 23-27deg or from 185-190deg), a study of the 
     area by Maurizio Cecchini (member of the PNdR Luna UAI) for 
     the confirmation of a probable volcanic dome in the area. The 
     highest possible resolution achievable, with telescopes at 
     least of 8" aperture or larger, is needed. All images, 
     sketches and visual reports should be e-mailed to: u a i . l u
