Title: UNEXPECTED GEOMAGNETIC STORM
Post by: ka1iic on January 07, 2015, 1545 UTC

A G2-class geomagnetic storm erupted during the early hours of Jan. 7th, sparking bright auroras around the Arctic Circle. What happened? The interplanetary magnetic field (IMF) near Earth tipped south, opening a crack in our planet's magnetosphere. Solar wind poured in to fuel the storm

During this season geomagnetic storms have been everything but unexpected. Total crap on low frequencies months after months.

Kyoto DST (http://wdc.kugi.kyoto-u.ac.jp/dst_realtime/presentmonth/) dropped to -105 and Kp went up to 7. Yay.
