Dear Matus,

Unexpected excellent surprise here.

I have been able to directly contact the Author of the enclosed Moonrise Picture.

He informed me that the Lady Moon and Archangel picture was taken on Jan 26th, 2024, and not on the previous day.

Wonderful information to me because for my earlier 25 Jan computations I could not adequately reconcile the Steeple left side Azimuth at 063°+/-1° derived from the picture (see attached Cadaster plan) with the Moon Azimut and Height for the 25 Jan.

One day later, it has all become much more simple and consistent.

I have done all the computations all over again.

From the following 4 intermediate results obtained from the picture with the updated Moon SD at 0.494° (instead of the previous value at 0.50° for the Jan 25th, 2024) and with the Steeple at N46°49.00N / 000°53.00' / Alt 275m , i.e. :

(1) - Photographer at 2.33 NM from the Steeple, (2) :xMoon Azimuth at 063.5°, (3) : Moon LL at 1°49.7' and (4) : Moon UL at 2°17'

obtain :

Observation time at 17h53m55s UT and final computed position at 46°48.84'N / 000°56.04'W

To be compared with the attached true position indicated by the Photographer.

Computed astronomical position from the picture falls just a little less than 0.1 NM from true position.

From the steeple, the computed azimuth matches the real one to 0.3° and the distance is too short by 0.096 NM, i.e. 0.1 NM (180 m).

The actual picture time computed as 17h53m55s is accurate to probably +/-30s and almost certainly to +/- 1 minute of time.
