    Hi Greg,

    You found:
    "6 March 2011
    UT 02:16:00
    ISS Lat. 39* N Lon. 88* W"

    Well, that's re-assuring! My original result was 39.0N, 88.0W at 02:17 UT. :) It appears that our approaches to this have been quite different, but to get so close a match must mean we're in the right ballpark. I think the lat/lon position can be refined a fair bit (without resorting to using the orbital data) but since the position of the Moon relative to the stars of Pisces can only be judged to the nearest half a minute of arc at best from this photo, the UT can only be determined to the nearest minute of time. So I don't anticipate any improvement there.

    By the way, I don't know if I've mentioned yet that photos like these are the astronauts' equivalent of vacation snapshots. They take these primarily for their own pleasure and for the benefit of public relations and providing that vicarious experience of "being there" that keeps people on the ground interested in space flight. This is literally a photo "shot out the window" with a handheld digital camera. Imagine what could be done with a photo where some effort had gone into making it navigation-quality.
