[SADXA] X7 x-ray solar flare in progress

[Jim Henderson]

    Yep, it is a biggie, although being rated at 5.4. The difference to the 
bands is much like whether you were run over by a 25 car freight train, or a 
100. It will still rank in the top 10 flares this cycle.

    10m will recover from the flare first, then 12m, etc...  absorption will
remain high on lower bands. Just about time things recover, the slower speed 
solar winds from the X1 and concurrent CME on 5 Mar will arrive.

    Looking at all the flurry of C and M class flares this spot has produced 
in such a short time, it is highly probably to see a couple more M and maybe 
even X flare before it rotates off.

    Just might see some after-dark enhancements as well.

An X6 or X7 strength x-ray solar flare just took out the entire 10-m band,
except for that part of it in darkness, on the E. coast of the USA, where
I've just been in touch with FL and SC.

The Pacific had been coming in this afternoon, and I heard Sonny, KH6CB
from Honolulu well, then the flare began. I'm watching the flare still 
rising at:

or, for the finer time-tick 1-minute version (where I see the flare has 
already
peaked and is beginning to fall):

http://www.swpc.noaa.gov/rt_plots/xray_1m.html

(but you fellows probably already know how to use these resources)

I'll be listening for 10m to recover this evening. It might be a good 
afternoon
and evening for the Pacific, once the ionosphere recovers from the shock
of the instant ionization and begins to stratify again. But the x-ray flux 
will
remain at gang-busters intensity for many hours, I think. Watch for more
such big flares this week.


The flare might also take out the low bands, for a longer time than the 10-m 
band.
But we'll have to see. Whatever the case, don't miss out on gauging the
effects of this flare for yourself, the largest of Solar Cycle-24 thus far.
There might be some good DX in there for us; or maybe not!
