    Solstice Sun Lines
    From: Tracy Shrier
    Date: 2017 Dec 23, 20:22 -0800

    I was lucky enough to be flying on the Solstice, and doubly lucky to have a good leg to try some Sun lines. The only draw back was the huge jetstream Thursday, so we were battling continuous turbulence. Tried to get three sights 5 minutes apart for the traditional groundspeed plot. Turbulence was such, coupled with the oblique angle of the LOP's, that the results were not particularly accurate or useful this time; but still good fun on a special day.  hs' ranged from 9°10' to 8°30'. Declination for all three sights was S26°26.1', dead bottom on the Solstice per the Air Almanac.

    Attached is the plot for your enjoyment.
