So, may get some Aurora out of this after all.

Before people go bonkers I'm sure this doesn't mean the end of the world; it's still going to be weaker than if it was pointed absolutely directly at earth.

And while it's the largest ever recorded by a huge margin, we've only really been "recording" flares in a meaningful way for about 25-30 years or so.

I'm sure humanity has survived hundreds of hits like this :-)

The largest ever was an X20 on February 2, 2001, which wasn't pointed at Earth at all and I suspect most people didn't exactly notice anything.

These guys have a history of being far more accurate than US Government agencies, will take them a while before they issue a CME impact forecast.

This is probably caused by Universal Warming. Ya think?

Estimated plane of sky velocity for this event is 2381 km/sec, although it is probable the true velocity is above 2400 km/sec because there is some evidence for acceleration of the CME.

I'm glad they cleared that up. I took one look at that thing and said, "There's no way in heck it's only going 2381 km/sec. It has to be going at least 19 km/sec faster than that."

It must be big.

The tanning parlor not far from me just lowered their prices 30%.

I'm sure this doesn't mean the end of the word

Good, because I have a nail appointment on Friday....

Definitely one for the record books.
If you find the words "first, last, smallest, largest and ever recorded" especially interesting then: you might want to read and have your say here

I hope this will somehow take care of all the dog gone leaves in my yard

If this doesn't/didn't upset Hillary!s broom riding, I don't know what would.......

Can the Enterprise use phasers or photon torpedos to stop it?

SEC now says it was an X-28 flare:

Yesterday's X17-plus flare began at 04/1929Z and
saturated the GOES X-ray sensor from 04/1944Z to 04/1956Z. Analysis
of available data from this event yield an estimated peak flux of
X28 at about 04/1950Z.
