No, not the CME.  A CME is particles of matter traveling at
non-relativistic speeds and usually takes a couple of days to reach earth.

The initial effects of a solar flare include the arrival of X-rays
(coincident with us seeing the flare), and those ionize the upper
atmosphere and cause radio blackouts.  That was what you saw the effects of.

This one surprised us and arrived earlier today (Thursday), way ahead of
schedule.  It was quite energetic.  It triggered a few instances of a G-4
(4 out of 5, "Severe") geomagnetic storm.  Also Kp=8.3.

Alas, I am unable to see any auroras yet.  :-(   Still hoping.
