What's this guy saying about the magnetosphere heating up?
That it's not coming from the sun, but from the Earth???
Anyone understand what's really happening?

Quoting: Anonymous Coward 6129544 The model from NICT is a realtime simulation based on data from the ACE spacecraft so it's impossible for it to show anything coming FROM Earth. The ACE satellite orbits at the LaGrange position about 1 million miles from Earth-between the Sun and Earth.

The ACE data is fed into computer simulation in Japan at NICT.

Anyway, so far geo-magnetic activity is Quiet as measured by the Kp Index (K=2 on a scale of 0-9). I do find it strange however that the pressure in the simulation looks so intense for such a weak disturbance. There was a forecast for increased solar wind due to coronal hole windstream. Earlier today I personally forecast a magnetic disturbance from some solar plasma ejected from a CME earlier in the week (I think it's on the page before this one).
HOLD THE PRESSES! NOAA ISSUES WARNING.
Space Weather Message Code: WARK04
Serial Number: 1846
Issue Time: 2011 Dec 03 0025 UTC
WARNING: Geomagnetic K-index of 4 expected
Valid From: 2011 Dec 03 0130 UTC
Valid To: 2011 Dec 03 0600 UTC
Warning Condition: Onset
All in all, this appears to nothing more than a weak disturbance. Although quiet earlier, Canada is now seeing some auroral activity.
