[via drudgereport.com - maybe this this why the radio was
on the blink. past events have impacted infrastructure...]

May 15, 2005 — Forecasters at the NOAA Space Environment Center in
Boulder, Colo., observed a geomagnetic storm on Sunday, May 15, which
they classified as an extreme event, measuring G-5—the highest level—on
the NOAA Space Weather Scales. (image...)

"This event registered a 9 on the K-Index, which measures the maximum
deviation of the Earth's magnetic field in a given three-hour period,"
said Gayle Nelson, lead operations specialist at NOAA Space Environment
Center. "The scale ranges from 0 to 9, with 9 being the highest. This
was a significant event."

Possible impacts from such a geomagnetic storm include widespread power
system voltage control problems; some grid systems may experience
complete collapse or blackouts. Transformers may experience damage.
Spacecraft operations may experience extensive surface charging;
problems with orientation; uplink/downlink and tracking satellites.
Satellite navigation may be degraded for days, and low-frequency radio
navigation can be out for hours. Reports received by the NOAA Space
Environment Center indicate that such impacts have been observed in the
United States.

NOAA forecasters said the probability of another major event of this
type is unlikely, however, other minor level (G-1) geomagnetic storms
are possible within the next 24 hours.

This event was forecast by NOAA as the result of a solar flare that
occurred on Friday, May 13.
