Hello, Frank!
I am still very confused about all this problem. Of course, I used SD of the Moon as a measuring tool. Ignoring the augmentation I get about 15° 11’ far limb Lunar Distance.
Assuming we don’t no anything about the location, it is still possible to find the Curve of Positon where such a distance could be observed (curve of position is the intersection of the surface of the Earth with a virtual 3D cone with vertex at the center of the Moon). I attached pdf file with graphical representation of all this.
If the initial photo where correct it would be possible to narrow down the position using the angle between the direction from the Moon to Jupiter and the direction from the Moon to the Sun. But SOMETHING IS TOTALY WRONG HERE. The positon of Jupiter is in different place (I attached simulation from 3 points which are located on the Curve of Position)!
If the blur object is really Jupiter, it is not where it shoud be! There is no place on the Curve of Position where it would be possible to observe such an angle between above mentioned directions as in the initial photo. I really don’t understand what’s going on here.
