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?

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.

All in all, this appears to nothing more than a weak disturbance. Although quiet earlier, Canada is now seeing some auroral activity.
