ALERT: Geomagnetic K-index of 7 (G3)
« on: September 12, 2014, 05:43:12 PM »
This is the highest K-index I've seen reported since moving back to Cal. A K index of 5 can allow photographs to pick up Aurora in CA. This is many times higher. If your in a dark place looking north you might check if you can see or image a glow. A friend of mine has had success in 2012 around Napa, Gilroy, North of Stockton.
