A CME is expected to hit earth Sunday night/Monday. They haven't said what class it is.

I do not really understand the ratings and explanation on the linked page.  About all I could understand is that we are not going to fry from this one and its really not much of anything.

Someone please confirm this for me.

G2 isn't too bad. 

G scale 1-3 is minor.  G4 and 5 would make me nervous.
-NOAA def.
G2 (Moderate) Geomagnetic Storm Impacts
Power systems: High-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage.
Spacecraft operations: Corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.).
-
events in the G scale mostly involve power transmission, radio and satellites.  the link below is the low level events.

i work in the radio industry.  here is the noaa page i find most useful.  the earlier link Nemo is from the email alerts.
this one and the PDF might help more.

here is an overview

Ok, one last note.  the above scales are for typical events.  if you hear a forecast for higher levels, just remember two things.  the scales are log10 if the earth were to be hit it wouldn't be good.  i keep a weather eye out for "M" and "X" class.
