Largest Solar Flare Ever Recorded (X30-X40) DOES have an Earth-Directed Component

Solar-Terrestrial Dispatch Mailing List ^

[John H K]

The X18+ solar flare has been associated with a high velocity FULL HALO coronal mass ejection. There IS an Earthward directed component. 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.

True x-ray intensity is unknown, but is probably near the X30 x-ray level (possibly between X30 and X40). VERY impressive event! Definitely one for the record books.

We have no idea yet when this one might impact the Earth or how strong the impact might be. We're waiting for a bit more data to arrive before we start the number crunching.

Ok...now explain this in terms that I might understand, please!

It blowed up real good.

Australia (VK6 & VK8) into the PNW on 50mHz late afternoon 31 October.

Wow! Man, that makes me wish I had a 6 meter antenna up. OK, I wish I had any antenna up right now, the joys of apartment living. :)

It reads like the Income Tax Laws doesn't it?

Maybe the same people are behind income taxes and solar flares. I'm thinking "persons of cloven hoof."

They must spend half of each orbit (daylight portion) in the "sheltered" portion of the ISS. I really doubt that it provides much.

The neutrons and energetic gamma rays will just pass right through that wimpy little station (and it's occupants).

People around here say not to worry, the charged particles are shielded by the earth's magnetosphere. But I can't help but thing there is a lot of bremsstrahlung, compton scattering, pair production, and secondary gamma emission going on.

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.

wonder wil the mecca boys see this as another sign....

to quote the film gremlins 2

It looks like the sun is going back to normal, but what is normal ? It started on the 15th of Oct, and it ends today,hmmm

Everything on Earth is about to resemble a 7-11 hotdog that has been left on that rolling thingy for about a week.....

The Sun farted in our general direction

The most well-understood explanation I've heard yet. Thanks for the laugh... and the profound truth.
