Unexpected Geomagnetic Storm Could Disturb HF Bands, Enhance 6 Meters

01/07/2015

Spaceweather.com reports that a G2-class geomagnetic storm erupted during the early hours of January 7, sparking bright auroras around the Arctic Circle. “The interplanetary magnetic field (IMF) near Earth tipped south, opening a crack in our planet's magnetosphere,” Spaceweather explained. “Solar wind poured in to fuel the storm.”

With the A index at 20 and the K index at 7 (as of 1430 UTC), HF conditions are predicted to be poor today and tonight. Joe Reisert, W1JR, told The Daily DX that there "could be lots of disturbances today [and] depressed HF conditions with aurora tonight, if the storm stays at this level.” Reisert advised keeping an eye on 6 meters, where radio amateurs have been taking advantage of F2 transatlantic openings.
