Not really the flares visible portion is traveling at the speed of
light yes, but the flare itself is

On the other hand, it's rather EM wave which is more harmful to

deviated by terrestrial magnetic field whereas em wave is unaffected.

Yeh, I guess it is smiling at us after spitting in our general direction ;-)

A few facts as satellite coms are above 1 GHz, there will be no effect

I'll explain why
the increase in magnetic flux caused by a solar flare has several effect
1. it changes the properties of the ionosphere, which short wave comms
relies on , hence the short

I was trying to keep it simple, so it was understandable by those
without any RF experience.
As for AMSAT most uplinks are now above 430 MHz, and those with
downlinks below 430MHz are old/obsolete ie AO10.
If you want to take it further , either off list , or on air or if you
must echolink

Could the em wave have a lot of energy at 2.4ghz? My wireless connection

Supposedly the max rating for such a storm is G5, this storm is
supposed to be G3 or so.
