Could be. The higher the latitude, the more effect it had. I had all my
stuff disconnected.

We had a 50/50 chance, and did get lucky. The flare had a south pole
magnetic field. We only lost 2 satellites. A few vhf radios went on the
fritz yesterday, as well as GPS errors and some radar fuzz.

A north pole'd flare could have caused a bit of havoc with the power
grid and other electronic gadgets.

Yesterday my ICOM vhf (which has DSC capability) would suddenly change to
channel 16 and emit a very loud ambulance siren type sound from the speaker.
The volume of the sound was not controllable and be canceled by changeing
channels or pushing the DSC button.This happened quite a few times. Today I
tested the unit by leaving it on for a good while , checks OK. So could this
be caused by solar flares?
