SOLAR WIND SPARKS GEOMAGNETIC STORMS
NOAA forecasters estimate an 80% chance of polar geomagnetic storms on Oct. 8th as a high speed solar wind stream buffets Earth's magnetic field. This marks the third day in a row of geomagnetic storms and bright auroras around the Arctic Circle. Last night, P-M Hedén photographed this outburst over his backyard in Vallentuna, Sweden.



Hedén is a veteran observer of auroras and not easily impressed. "Woooooow!" he says. "This was a very impressive display."

At their peak on Oct. 7th, the storms registered 7 (strong) on the 0-to-9 Kp scale of geomagnetic activity. A repeat performance is possible on Oct. 8th as the solar wind continues to blow. High-latitude sky watchers should remain alert for auroras after nightfall.
