Aurora Alert for October 13th
A persistent G1-class geomagnetic storm on Oct 13th (still underway as this alert is being written) has sparked bright auroras around the Arctic Circle, spurring reports of Northern Lights from Scandinavia, Greenland, Canada, and several northern-tier US states. More auroras are in the offing. NOAA forecasters estimate a 40% chance of continued storms on Oct. 14-15 in response to a high-speed stream of solar wind.
