Lunar Observing Schedule for: Lithuiania - Vilnius



Produced by the Department of Physics at Aberystwyth University, UK
Ill is percentage illumination of the Moon


2025-Nov-03 UT 18:31-20:29 Ill=95% Sirsalis

     BAA Request: Sirsalis. We are trying to replicate, using 
     modern day images, a sketch in Plate II in BAA The Moon 
     from published: 1950 Jun Vol 1, No. 1. Its for a sketch by 
     D.W.G. Arthur from 1949 Jan 12. Please send any images to: 
     a t c @ a b e r . a c. u k .


2025-Nov-04 UT 16:51-18:49 Ill=99% Bailly

     BAA Request. Please observe visually or image this crater in 
     colour to see if you can detect any colour on part of the 
     floor. Please email any observations to:
     a t c @ a b e r . a c. u k .


2025-Nov-05 UT 17:34-19:44 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 


2025-Nov-07 UT 01:12-01:47 Ill=97% Mons_Vinogradov

     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 


2025-Nov-08 UT 18:25-04:29 Ill=85% Cyrillus

     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


2025-Nov-10 UT 03:05-04:04 Ill=72% Jansen

     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 .

2025-Nov-26 UT 18:51-19:10 Ill=34% Apianus_D

     BAA Request: On 2011 Oct 03 Fran Power both observed visually a 
     range of colours on the rim of this crater. Although the Moon 
     was quite low in the sky, this effect was not seen anywhere else 
     on the Moon. The appearance was confirmed by another observer 
     using the same telescope (without being told what they were 
     supposed to see). An image was obtained which seems to show some 
     strong colour in this specific location, and nowhere else. 
     Please re-observe this area. Telescopes of aperture 6" and 
     larger are needed (refractors not allowed) - observations with 
     the Moon low down in the sky are desirable to see if the 
     atmosphere can reporduce this effect. Please send any sketches 
     or images to: a t c @ a b e r . a c . u k


2025-Nov-27 UT 15:05-16:58 Ill=44% Earthshine: November Orionds: ZHR=3 vel=44km/s

     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:
     ALPO - email: c u d n i k @ s b c g l o b a l . n e t
     BAA - email: a t c @ a b e r . a c . u k

2025-Nov-27 UT 17:39-18:22 Ill=44% Ptolemaeus

     BAA Request: Examine the floor visually, sketch, or image to 
     show the progression of the shadow spires across floor. 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 N. Travnok (Brazil) on 2020 Jul 27 UT 23:00 who 
     commented on an unusual appearance to the floor. It would be 
     really useful to have visual observing of the appearance and 
     please note down what the seeing conditions are like. If you 
     want to image it at high resolution, please go ahead but 
     remember that any image stacking should not be from sections 
     of video of longer than 1 min duration as the shadows change 
     in length rather quickly at sunrise. Any sketches, visual  
     descriptions, or images taken, should be emailed to: 
     a t c @ a b e r . a c. u k 


2025-Nov-28 UT 15:34-19:29 Ill=54% Plato

     Plato's Hook: a hook like effect in one of the shadow spires in Plato, 
     near a rim - this is a Clair-Obscur effect. It was first seen by 
     H.P.Wilkins in 1952. 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.


2025-Nov-28 UT 16:21-16:55 Ill=54% 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:
