As it has been an item here, maybe it's not too far offtopic...
hfradio.org sent out the following warning:
> Sunspot group AR9591 produced an X5-class solar

What i am confused about is the phrase "...resulted within moments".
Ok, let's see.
Light takes roughly 8 minutes from sun to earth.
What causes such effects in the ionosphere?
Ionized particles, i think, or am i wrong?
Ionized particles have mass, or am i wrong?
How can a mass-carrying particle arrive within moments (i assume hfradio.org
meant within 8 minutes, in any case with light speed)?
AFAIK mass carrying particles takes up to 2 days to reach earth after a CME
or so...
So what is wrong in my thinking?
