SEVERE SOLAR ACTIVITY ALERT
« on: March 17, 2015, 2241 UTC »
After a quick tune around the bands around 2200 UTC, I noticed that the propagation was very disturbed and the noise was really bad...things just weren't making it through that are daily loggings here. I checked the NOAA propagation report and sure enough...A-index of 100 and K-index of 7. Aurora watchers should have a field day this evening!
 Should I put on my tinfoil hat just to be on the safe side ;D

EDIT:Technically speaking, this is actually a geomagnetic field activity alert ;)
         "Coronal Mass Ejection" or CME from March 11th has reached us

SFI = 114   A = 117   K = 8

I don't recall the last time the A-Index was higher than the Solar Flux ???

Apparently, auroral  activity was seen as far south as the Dakotas in the hours before sunrise today.
The storm is subsiding but still active, so a chance to see some may be possible after dark in the northern tier of the U.S.
As an aside, the only time signal I can hear at the moment is WWV's 5 MHz signal.
