Gentlemen:

We are all probably well advised to disconnect any/all antennas
during this pending event,...especially long wire radiators.

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/NOAAscales

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.
