Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 055 Issued at 0245Z on 24 FEB 2000 This report is compiled from data received at SWO on 23 FEB
A. Energetic Events
Begin  Max  End  Rgn   Loc   Xray  Op 245MHz 10cm   Sweep

B. Proton Events
None
C. Geomagnetic Activity Summary
HE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. THE FIELD INCREASED TO ACTIVE BETWEEN 15Z AND 18Z DUE TO THE ARRIVAL OF A CO-ROTATING INTERACTION REGION (CIR) SEEN IN ACE DATA. THIS CIR BROUGHT INCREASED SOLAR WIND VELOCITIES AND MAGNETIC FIELD STRENGTH; BZ FLUCTUATED WILDLY BETWEEN -15 AND 10 NT. THE CIR HERALDS THE EXPECTED RETURN OF A HIGH SPEED CORONAL HOLE STREAM.
