By what Space Weather is saying we just missed a big one.
(The explosion also produced a CME, but because the blast site was so close to the sun’s western limb, the cloud is not heading toward our planet) Gypsy if it was coming at us it would take down the grid! We have had some close calls!
So this one was an X1.3 you can read some at http://www.ips.gov.au/Solar/6/1#flareclass
