A solar flare and a geomagnetic storm are different things, you cannot directly compare the strength of a flare on the sun and the resulting geomagnetic storm caused by a CME associated with the flare hitting earth.

Importantly, the CME launched by the 2003 flare went away from Earth and didn't hit us.

Thanks, I know that solar flare, CME, and geomagnetic storm are 3 separate things, but I thought that they would have correlated with each other.

So was the G5 storm in 2003 the result of *just* a glancing blow????
