[Scan-DC] Conditions-Addendum

[al]

This one came this morn.

The "aurora sightings...as far south as Arizona" shows how strong 
conditions have & are being felt.

  Sure would be neat to see an aurora,natural not man made,around here.

>NOAA Region 808 continues to produce strong (R3) radio blackouts and has

>NOAA's Space Environment Center (SEC) in Boulder, Colorado, observed
>the strong (G4) geomagnetic storming between 2:00 a.m. and 5:00 a.m.
