SOLAR WATCH * Huge X8.2 Flare Sept. 10, 2017! (Updated Daily)

Excerpt for future reference;

A solar eruption is followed by a one-two-three punch, said Antti Pulkkinen, a physicist at NASA's Goddard Space Flight Center in Maryland and Catholic University.

First comes electromagnetic radiation, followed by radiation in the form of protons.

Then, finally the coronal mass ejection - that's the plasma from the sun itself - hits. Usually that travels at about 1 or 2 million miles per hour, but this storm is particularly speedy and is shooting out at 4 million miles per hour, Biesecker said.

Just having fun brutha...best wishes....

All in good faith.

Namaste.

i have seen CME's hit without a Bz flip
the Bz is the north / south direction of the solar wind
so, the direction of the Bz has everything to do with the direction of hit the CME takes when it arrives
if the CME is northward, it will arrive on our northside and we will see the winds shift north (green +)

huh.

ok

does that mean that the polarity of the CME drives the polarity of the EMF? that would make sense.

what i understand about south Bz is that it allows for strong energy transfer between our field and the IMF: is this correct?

plus according to recent charts, a CME hits with strong waves of alternating Bz polarity. Was that true for previous CME impacts?

i think i'm seeing the first signs of geofield wobble on HAARP now... already got somethin on the Russian magnometer

Found it :)

You just needed to refesh your smilie page

LOL great one

Solar Storm Threat Analysis-a easy to read, yet thorough overview of Solar Particle Events' effects on Earth and infrastructure. Besides insights into power grids, etc., the author (James Marusek) had this to say about LEO satellite risks:

" A high-energy particle from an SPE can penetrate the wall of a satellite and deposit sufficient charge to cause an electrical upset to a circuit switch, false command, memory state change or loss. As the nuclear particles collide
within the spacecraft, they release electrons that build up an internal dielectric charge. This static charge can destroy circuitry on electronic boards. The particles can also change data and instructions stored in computer memory.

Some of the memory damage is soft causing Single Event Upset (SEU). Generally, this anomaly can be corrected by a computer reboot. But some of the damage can be hard causing unrepairable physical damage to the junction of
the microcircuit. These types of failures can be fatal."

From what I can tell from my limited research, the GOES electron flux detector suffered one of these temporary upsets due to the accumulated charge of 24-hour magnetic storm and not from the proton event. Of course the proton event may have been the straw that broke the camel's back. It looks like they got it to re-boot (maybe).

Photo of fried transformer from 1989's mag-storm from New Jersey's Salem Nuclear plant. These transformers are as big as a house, cost over $10 million apiece, and take up to a year to replace under good conditions. Hundreds of these babies could be at risk in an extreme ground-current event.

I see that =) Hope you don't mind someone just reading/watching and trying to learn though, haha. Been trying to follow the sun stuff for a bit now, and trying to understand it all...

huh.nice.

makes sense too.
be nice to have that density meter up again.

lots of energy out there, to be sure...

There's a lot of high-falootin' physics papers to wade through here in cyber-space (and lots of 'em ya gotta pay for). Anyway, after much research I've determined the answer is.....wait for it.......
.......YES.

Yes there have been observations of these in the past. Evidently, this is a very complicated circumstance that is dependent on the angles of the CMEs/flares, their velocities, and the latitude of their respective origins. In the scenario you suggest, we would see an intensifying effect of the solar energetic particles.

Also, as El Q seemed to suggest, the coronal hole may also have an effect on CMEs and SEPs. I'm no physicist so my knowledge is quite limited in this....but there's lots of difficult-to-read heliophysics research on this stuff out there.

Here's one:
"The intensity variation due to CME interaction reported in [1] is confirmed by expanding the investigation to all the large SEP events of solar cycle 23. The large SEP events are separated into two groups, one associated with CMEs running into other CMEs, and the other with CMEs running into the ambient solar wind. SEP events with CME interaction generally have a higher intensity. New possibilities such as the influence of coronal holes on the SEP intensity are also discussed. For example, the presence of a large coronal hole between a well-connected eruption and the solar disk center may render the shock poorly connected because of the interaction between the CME and the coronal hole. This point is illustrated using the 2004 December 3 SEP event delayed by about 12 hours from the onset of the associated CME. There is no other event at the Sun that can be associated with the SEP onset. This event is consistent with the possibility that the coronal hole interaction influences the connectivity of the CMEs that produce SEPs, and hence the intensity of the SEP event."

nice 'voice' here :

"A powerful solar eruption is expected to blast a stream of charged particles toward Earth tomorrow (Jan. 24), as the strongest radiation storm since 2005 rages on the sun."

just killen time a waiting...
and:

"The "geoeffectiveness" of CMEs --i. e., their ability to disturb the Earth's magnetosphere-- is a function of their speed, the strength of their magnetic field, and the presence of a strong southward magnetic field component."

from: [link to pluto.space.swri.edu]

which is why Bz has suddenly become so interesting to me...
we got speed, and we can measure Bz still, so if that sucker goes deep 'red' then we can expect strong interactions?

When are you gonna come down?
When are you going to land....

I've seen older SOHO movies of these rare proton "snow-globe" storms but I never knew they lasted so long. This is the first time I've witnessed such an event in real-time and I'm amazed that the blizzard effect at SOHO has gone on nearly 20 hours now. Forgive me if this was already posted, but here's the COR 3 view of the past two days or so.

"Full power to the shields, Mr. Scott!"

Many Thanks Hugh,
Just popped back in, going to wade into it
forthwith. As you say, there are a glut of resources
available on the web...maybe too much. Posted in hopes
that someone here had the "knowing" already and could
evade such a tedious search. As said will dig in shorty.
Again, thanks.

Tnx ..

Does not looking good ..

Hi tom.....good to see ya!!!

All three bands of the GOES 13 Monitor - 10, 50
and 100 Mev definitively up-ticking NOW.

Hey JOG, no problema. I got a little cross-eyed trying read all that stuff, but I learned some things along the way. Cheers.



Here's the link I was searching for and I just now found it.
Living Reviews of Solar Physics (search for cutting edge solar science papers):

Thats the one!!!
i clicked refresh and saw you posted hahaha

Hi Ninz...glad to see you back

Full power to the shields, Mr. Scott!

Powerfull Jan 23rd CME Arriving Now!

:) nice seeing you OG

hey, someone make a new thread for the cme arrival and me and tom will be on it with support!

whos up for it?
it will get pinned

I see a tiny little uptick in the ACE solar wind. This may be the shock-front, eh?
