There's a youtube video of a man taking 2 Sun sights and asking you to figure out where he's located. Greg got it correct (as you can read in the comments section of the video) using, I assume, his Palm (Pilot?) with Pilot Navigator Version 6.9.

The time WWV signals are very heard hear and the guy makes little effort to provide you with time or Hs- in other words his presentation is  sloppy.

What I'm trying to figure out is how you get a position fix when you don't have an obvious Ap Latitude or Ap Longitude? And, I can't plot an intercept that's many hundreds of miles away on a UPS. However, I did figure out the time and Hs of both sights and using Peter Hakel's Lop.xls a fix was obtained. But I'd like to know how to do it on paper either by adjusting the Ap Longitude and resulting LHA which I suppose is the only thing you can adjust. I'm no expert in these matters.

An AH was used in both shots.

Here are the particulars from the video-

1rst shot Date- 2/20/2010

Time- 17:26:26 UTC

Hs- 40d 18.2min

Limb observed- Upper Limb

My determinations-

GHA 78d 11min

Declination- S 10d 46.4min

Ho- 19d 50.5min

2nd shot Date- 2/21/2010

Time- 00:16:02 UTC

Hs- 24d 04.4 min

Limb observed- Lower Limb

My determinations-

GHA 180d 35.5min

Declination- S 10d 40.3min

Ho- 12d 14.1min

Using Peter Hakel's LOP.xls the following fix was obtained-

N 47d 28.8min

W 122d 13.9min
