I lately stumbled upon the attached raising Moon picture.

Let's use it for another Navigation Quizz.

Picture taken on Jan 25th, 2024, in the vicinity of the January 2024 Full Moon.

Steeple Coordinates 46°49.90'N / 000°.52.98'W   

Steeple height above ground : 52 meters including the golden plated Archangel Saint Michael statue (see also attached picture)

The steeple is built on top of a hill.

By default, one should consider that from the Observer's ground level to the steeple ground level the mean upwards slope is approximately 2°.

A careful look at Google Earth, or even better here , can help finding out the Moon Azimuth to within a few degrees. As per the hint given in the previous paragraph, an independent and reliable check on its Azimuth is the Moon altitude of course which should stay consistent with the picture.

Can you determine :

(1) - UT picture Time,

(2) - The Photograph's position.

I would surmise that we can derive picture UT at +/- 1 minute of time, and the Photograph's Position accuracy within 0.2 NM, and probably within 0.1 NM.

If required and for your convenience (Data assumed to be accurate to +/- 4" and given with 1 extra digit to "kill" round off end-errors):

25 Jan 2024 - 16:00 UT Moon GHA = 236°36.29'    Moon Dec  =  23°52.28' N Moon HP = 54.71'

25 Jan 2024 - 17:00 UT Moon GHA = 251°06.73'  Moon Dec  23°44.07'   Moon HP  = 54.70'

For refraction assume standard data (i.e. QFE = 1013.25 hPa and T = +10°C)

Since this village is within one hour of driving distance from here, and according to the interest raised by this quizz, I may drive and take a few pictures from there pretty soon, i.e. before the spring tree leaves blossom back.

Enjoy,

Kermit
