Sunspot group #10798/10808 unleashed
an X1.5 solar flare and attendant geoeffective (Earth facing) coronal mass
ejection on Tuesday 09/13/05 at 1927 UTC. The CME is screaming along at
1500 km/s and should hit Earth's magnetic field later this evening or early
tomorrow morning UTC.
I expected a more prolonged severe
geomagnetic storm (Kp-9) this time around and low latitude visible aurora is
more likely this time.
