Mach-2-eyeball first pass.

Average time: 14h 24m 55s UT
Average Hs:  104° 40' 28"
Average IC: +02!8
Average Ha 104° 43' 16"
Average Ha /2 = 52° 21!6
Refraction: -0!7
Ho: 52° 20!9
Azimuth: 100°

Longitude: 76° 25!7 W

Which, IF I'm close, puts you in Hampton, VA.
Specifically, playing in traffic on SR600 :-)
