2024-Mar-08 UT 10:27-11:29 Ill=5% 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


2024-Mar-11 UT 00:05-01:13 Ill=0% Moon

2024-Mar-14 UT 00:25-02:01 Ill=18% 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 morning, that it 
     starts to show 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

2024-Mar-18 UT 01:41-02:39 Ill=59% Eudoxus

     BAA Request: Eudoxus - please try to image the interior of 
     this crater. We are trying to explain an observation from 
     Meudon Observatory in France made in 1877 for which a fine 
     line of light was seen acress the crater in an E-W direction. 
     Please send any images to: a t c @ a b e r . a c. u k .


2024-Mar-19 UT 00:45-00:59 Ill=68% 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 .


2024-Mar-19 UT 03:42-04:16 Ill=69% Alphonsus

     BAA Request: Monitor the central peak for brightness changes. 
     Compare against the central peak of Arzachel, and other craters 
     with central peaks. If brightness changes do occur, do they 
     change with atmospheric seeing conditions? A small aperture 
     scope can be used for this study with a magnification in the 
     order of x120. Any brightness measurements or image sequences 
     made should be emailed to: 
     a t c @ a b e r . a c . u k


2024-Mar-19 UT 03:42-04:52 Ill=69% Tycho

     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


2024-Mar-21 UT 05:36-07:45 Ill=86% Plato

     BAA Request: How dark is the floor of Plato compared to other 
     dark areas on the Moon e.g. nearby Mare. Can you see central 
     craterlet on the floor? Is the floor of Plato brighter or 
     darker through a green filter than in other colours? 
     Alternatvely just take a colour image. Mimimum sized 
     telescope aperture: 6 inches.Please send any sketches, 
     monochrome images, or visual reports to: 
     a t c @ a b e r . a c. u k .


2024-Mar-22 UT 02:07-08:25 Ill=91% 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 


2024-Mar-22 UT 06:28-07:38 Ill=92% Vallis_Schroteri

     ALPO Request: The area to look at here  is to the west of 
     Herodotus, near the terminus of Valles Schroteri, where you 
     should be able to see four spots of light (just east of the 
     terminator). Are these better visible in red or blue light? The 
     original observation was made using Wratten 38A and Wratten 25 
     filters, but any blue and red filters will do, or indeed a 
     colour camera. Do these spots fade over time? If so, in what 
     order? If imaging, then time lapse imaging would be useful here.
     Minimum aperture telescope to use should be a 6", and if 
     possible a refractor - aim to use magnifications of around 114x 
     to 228x. Any visual descriptions, sketches of images should be 
     emailed to: a t c @ a b e r . a c. u k .


2024-Mar-23 UT 00:49-01:59 Ill=96% Prinz

     ALPO Request: Monitor this crater over time to see if there 
     are any brightness changes inside. A minimum sized scope to 
     use for this would be an 8" reflector. 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


2024-Mar-24 UT 00:38-02:16 Ill=99% Riccioli

     ALPO Request: Either visually observe or obtain a colour image 
     of this crater shortly after it has emerged from the sunrise 
     terminator. Minimum sized aperture scope needed: 5". Any 
     observations  or images should be emailed to: 
     a t c @ a b e r . a c . u k


2024-Mar-24 UT 02:41-03:39 Ill=99% Plato

     BAA Request: Two observers have reported colour on the rim 
     around this colongitude, once in 1938, and again in 2013. Please 
     take a look and report what you see, and where on the rim. 
     Please send any high resolution images, detailed sketches, or 
     visual descriptions to: a t c @ a b e r . a c. u k .


2024-Mar-24 UT 09:12-10:09 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 .


2024-Mar-25 UT 00:38-00:46 Ill=100% 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


2024-Mar-28 UT 04:59-10:58 Ill=92% 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
