SpaceWeather.com warning! M9.3 solar flare is here!

The simulator uses the data from the ACE satellite (shown above).

Agreed, definately wrong choice of words, however, still quite a bit of stress there. I find it shocking, albeit normal, the effects that are monitored.

I think it may be a problem with embedding the code for the particular image link, mine did the same thing. Not ruling out your theory though, just an observation.

Sudden drop in density and speed.
That's it? It's done?

reply to post by Phage


Think it would be possible for the equipment to malfunction due to the overtaking of the flares, and overloading the sensors?

reply to post by Techata

It's been through a lot worse than this.
The data is coming and there's nothing wrong with it.

reply to post by Phage


Yes, Yes it is, jumped the gun, internet explorer took a crap, stupid work computer. Just a thought on the possible sudden drop, i would expect it would dwindle off.

reply to post by Techata

It's not uncommon. But since this is supposed to be a combination of two CMEs something could still develop.

reply to post by Phage


Well I am on stand by.....awaiting any details that come out of this great magnetic happening.

I don't think it's quite finished yet. The Solar Wind Speed has increased and so has the density -

Solar wind speed: 630.3 km/sec density: 5.3 protons/cm3

The Wind Speed was previously around the 600 km/sec region and density was at 3.7 protons/cm3

An update of my previous post -

Solar wind speed: 619.5 km/sec density: 8.1 protons/cm3

For the more "expert" of our community . . . if we were to have another event, such as a strong M or even weak X-class flare in close succession to these last, wouldn't our magnetosphere be weakened and thus more vulnerable in its protection of our satellites . . . not to mention power-grids and people on the ground?

reply to post by nonnez

CMEs don't weaken the magnetosphere. They caused it to "wiggle" and it's a temporary effect, like wind producing ripples on water.

The activity over the last three hours resulted in a Kp index of 8. Thats pretty intense, a G4 level storm.


The high activity on the night side of the planet shows the intensity of the substorms produced by the CME. That activity is "averaged" into the activity elsewhere to produce the Kp (planetary) index.

Thats interesting! It looks as if it is still going on...

Am I correct to assume such?

reply to post by MamaJ

There's still activity.
If you look here you'll see that the Bz component (third graph down on the right) is very strongly "south". That keeps the geomagnetic activity high even though it seems most of the CME may have passed us.

whats all those white things flying around in the video of the flare?

"UPDATE: Analysts at the Goddard Space Weather Lab report a strong compression of Earth's magnetosphere in response to the CME impact. "Simulations indicate that the magnetopause separating magnetospheric and solar wind plasma is close to the geosynchronous orbit starting at about 19:20 UT on August 5th. Spacecraft (in these) orbits may be directly exposed to solar wind plasma and magnetic field."

Good chance for strong auroras tonight! I hope I have clear skies.

Made a video from some the pictures at www2.nict.go.jp...

At first I got them in 2 minute intervals, but made the rest from the archive using 15 minute intervals.

Heh...

Not a good time to be flying around the higher latitudes in the northern and southern hemispheres... pilots scrambling from sporatic radio transmission and instrumentation problems... or radiation warning systems going off forcing them to drop their altitudes.

No wonder these guys drink so much coffee during their shifts.
