    Re: GMT from Lunar Photo

    Assuming the photo was taken at the moment of occultation of the star at 1 o'clock, and using the lat/long as in Antoine's reply, David Herald's Lunar Occultation program gives the time of disappearance as 1:11:30.4 GMT

    Happy New Year to all

    From Mr. Google Earth Pro, Sky Village at N31°55.8' / W109°07.2' Altitude 1450 m

    STARTING POINT (before iterations if required)

    Approximate time 01:13 UT on Jan 05th, 2022

    Moon UL = 15°58.3'  Moon LL = 15°25.6' , hence Moon Augmented Diam = 32.6'

    Augmented D showing as 157 mm on my computer screen, 

    Given its position relatively to the Moon Horns, bottom right "bright spot" should yield a fairly resonable Lunar. It shows at 207.5 mm from the Far Limb on my screen, hence at an angle of 0°43.119' from the far limb of the Moon.

    Moon Coordinates close to RA = 21h21m12,57s DEC = -20°42'57"

    Unable so far to find any "resonable body" to match this bright spot. Saturn is too far away in azimuth (about 4° too much to the right). This Planet or Star does not either match of the 81 Standard Celnav French Ephémérides Nautiques Stars, nor any from the full list of the US NAL ..... No other planets seem close.

    Maybe Delta Capriconi might work, but no time for me to compute its apparent position to-nite. Well ... probably not, too south declination (20° or so) ...

    When I have time I will attempt digging something from the star catalogs.

    If no joy ultimately, I will be mulling over a totally different approach.
