For your next time sights, why not download a 19th century copy of Norie or Bowditch (or Martelli's Time Tables, if you want to join the party :)) right on your iPhone. I have quite a few navigation works on my smartphone (the infamous Samsung Galaxy S3 running Android).
Here's a short link to a bunch of options you can consider:

and modify your position until it produces the right altitude at the right GMT.-FER
