Space Weather Message Code: ALTK07
Serial Number: 90
Issue Time: 2015 Mar 17 1334 UTC

ALERT: Geomagnetic K-index of 7
Threshold Reached: 2015 Mar 17 1330 UTC
Synoptic Period: 1200-1500 UTC
 
Active Warning: Yes
NOAA Scale: G3 - Strong

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio - HF (high frequency) radio may be intermittent.
Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon.

This might be an opportunity for Aurora viewing and whistler listening...

And no drone/multicopter flying, especially those that rely on GPS for position fixes and the like.  K-index right now is 7 and I saw 8 earlier.  Given that it's just two days from the vernal equinox I'm not surprised that we're seeing/hearing terrestrial noise.  Satellite reception will get hammered for the next week or so.
