Lunar Observing Schedule for: Australia WA Perth



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


2026-Jul-02 UT 14:05-15:27 Ill=94% Torricelli_B

     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 .


2026-Jul-03 UT 13:45-17:37 Ill=88% 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


2026-Jul-07 UT 17:44-18:06 Ill=50% Tycho

     ALPO Request: What we are interested in here is time sequences 
     sketches or images of the central peak and shadowed interior 
     of the floor of this crater. Can you see any detail inside the 
     shadow? Is the shadow completely black in colour or is there 
     some greyness? How does the brightness of the central peak 
     change over time? All visual reports, sketches or colour 
     images should be emailed to:

2026-Jul-24 UT 09:32-10:57 Ill=77% Montes_Jura

     "Jewelled Handle": in Montes Jura - this is a Clair-Obscur effect. Its
     an illuminated arc. 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.


2026-Jul-24 UT 13:31-14:17 Ill=78% Tycho

     ALPO Request: Does the floor appear darker towards the NW? If 
     so, is it a bit more darker in blue light, e.g. Wratten 80A, 
     than in white light and other filters (e.g. Wratten 23A and 
     OR5). A 4" or larger diameter scope is needed for this study 
     - and if you have a refractor then use this. The 
     magnification should be around x180. 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


2026-Jul-24 UT 14:42-15:28 Ill=78% Posidonius

     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


2026-Jul-25 UT 09:46-11:43 Ill=85% Promontorium_Heraclides

     Cassini's Moon Maiden at Promontorium Heraclides - this is a Clair-Obscur effect.

2026-Jul-26 UT 19:25-20:04 Ill=92% Cavendish_E

     BAA Request: Cavendish E - we are attempting to check out two 
     reports made on 2021 Jun 22 UT 20:44 and 2025 Sep 04 UT 20:04 
     which both said that part of the northern rim of this crater 
     was as bright as Aristarchus. Visual observation or images 
     - high resolution and/or wide angle (to compare with other 
     bright features) would be welcome. Telescopes of aperture 5", 
     or larger, should be used. Please send any images to: 
     a t c @ a b e r . a c. u k .


2026-Jul-27 UT 15:41-16:04 Ill=96% Vallis_Schroteri

     ALPO Request: We need images or skecthes of the Cobra Head area, 
     with the aim of finding out if the region on its NE side looks 
     fuzzy at this stage in illumination. You need a telescope of 
     aperture 6 inches or above. Please send any sketches or images 
     captured to: a t c @ a b e r . a c. u k .


2026-Jul-27 UT 18:14-20:51 Ill=97% Mare_Frigoris

     ALPO Request: How dark is Mare Frigoris? Compare to other mare 
     areas or Plato. All visual brightness measurements, sketches or 
     monochrome 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


2026-Jul-30 UT 21:26-21:56 Ill=99% 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:
