I'm disappointed non of you smart guys are taking up this challenge. I'm too ignorant to offer a solution. The fact that I can't see or Horizon in the solar photograph makes me unable to discern it's elevation. I'm sure that with an almanac and knowing that the transit was occurring all of those angles are cipherable. Given only one time for the 9 images. It is hard to know the average time. and I'm thinking the error is in the range of 2 solar diameters, because we don't know if the time is the first, last or middle image. I am hoping someone takes a stab at it as I am looking for the teachable moment.
Yours in ignorance.

Here's a nice photo taken from the Netherlands yesterday by Marco Langbroek showing the International Space Station transiting the Sun. What was the observer's actual position? He provides the time in UT but there are multiple images combined into one, so we will have an elongated error ellipse for this fix. How long? What is the accuracy of the fix in the perpendicular direction?
