Thanks for the post. It explains a lot. Went up to St. Joseph Michigan on Lake Michigan today to spend boat dollars at the marina and do some celestial observations. Cloud cover and hazy horizon did not allow sextant activities.
I had my Garmin road GPS on as construction closed down my regular route. About 4:15 PM EDT the GPS complained of weak signal or no signal. It was basically non-functional on the trip home between 8:30 and 9:15.
My old Garman 76 does not like tree aprons, blizzards etc, but to date the road GPS seems to find a usable signal almost anywhere. All I could figure was jamming, solar flare, or replacement of a 2-year-old unit.
I had my sextant in the trunk, but of no use with the clouds. Had to rely on a map, DR and a compass. Scary ;-)

There's news of big solar activity yesterday that may lead to aurorae
Saturday and Sunday. The active region that produced the CME includes a
big sunspot group. I couldn't convince myself this afternoon that I
could see it without magnification, but it's plainly visible through a
sextant telescope of any power.
