X6.9 Solar Flare!

[SDO]

The largest solar flare yet this solar cycle occurred this morning, August 9, 2011 at 8:05 UT. This flare had a GOES X-ray magnitude of X6.9, meaning it was more than 3 times larger than the previous largest flare of this solar cycle - the X2.2 that occurred on Feb 15, 2011. Stay tuned for movies of this flare!https://blogger.googleusercontent.com/tracker/6369594138980582994-940501797538904861?l=sdoisgo.blogspot.com

does this mean it left the sun this morning or its hitting the earth this morning? i understand theres like a 2 day travel time or something.

A strong burst of radiation, a flare, was measured by the GOES satellite. The flare was also seen as a light flash in PROBA2/SWAP and SDO/AIA images. Solar radiation reaches the Earth after 8 minutes. This flare is up to now the strongest flare of the current solar cycle.

Shortly after the peak of the flare, the proton flux near Earth increased. GOES is also capable of measuring these energetic electrical particles. The Sun throws a whole bunch of these particles into space, more then usual. The proton flux passed the storm threshold. The storm level is not dramatic.

A plasma cloud left the Sun at the moment of the event. It is now travelling through space at a speed of more then 1000 km/s. At a speed of 1000 km/s and no deceleration, a cloud bridges the distance between the Sun and the Earth in 1 day and 17 hours. The plasma cloud is not directed straight to Earth. But a glancing blow is possible and can cause a geomagnetic storm.

Possible consequences on the day side of the Earth associated with the radiation burst:
radio communication can be interrupted – satellites orbitting just above the Earth atmosphere can feel a drag force – navigation systems based on satellites and signal passage through the ionosphere can be disturbed. Possible consequences associated with the proton event:
Additional radiation at the Earth poles and in space (ISS is vunerable) – Radio communication disruption at the poles

Additional effects are possible at arrival of the plasma cloud

phimonic..this is a cool visual. and this link takes me to a down load which is great but I cant seem to get the full link addresss.. can you rewrite the link so that I can take it elsewhere... maybe just but a space in the middle of it or something so the forum does not abbreviate it.?
