Joint USAF/NOAA Report of Solar and Geophysical Activity

:::::::::: CORRECTED COPY :::::::::: SDF Number 061 Issued at 2200Z on 01 MAR 2000

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 01-2100Z

SOLAR ACTIVITY HAS BEEN LOW. CONSENSUS OF THE REPORTS FOR REGION 8882 (S15 W45) INDICATE AN INCREASE IN ITS COMPLEXITY. IT AND REGION 8891 (S16 E08) REMAIN THE LARGEST, MOST COMPLEX REGIONS ON THE VISIBLE SUN. A SERIES OF CORONAL MASS EJECTIONS HAVE OCCURRED ABOVE THE SOUTHEAST LIMB AND SOME MAY BE ASSOCIATED WITH ACTIVITY IN REGION 8882, INDICATING A SOURCE NEAR THE CENTER OF THE DISK.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW TO MODERATE WITH A SMALL CHANCE OF MORE ENERGETIC X-RAY EVENTS, PRIMARILY FROM REGIONS 8888 AND 8892. IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 29/2100Z TO 01/2100Z: THE GEOMAGNETIC FIELD HAS BEEN ACTIVE. SOLAR WIND OBSERVATIONS FROM THE ACE SATELLITE INDICATE A TRANSITION OUT OF CORONAL HOLE-DRIVEN CONDITIONS IN THE PAST 24 HOURS. A RAPID CHANGE IN PARAMETERS AROUND 01/2000Z MAY BE ASSOCIATED WITH A SHOCK PASSAGE. ENERGETIC ELECTRON FLUX GREATER THAN 2 MEV AT GEOSYNCHRONOUS ORBIT REMAINED BELOW ALERT THRESHOLDS TODAY.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO REMAIN UNSETTLED TO ACTIVE. ACTIVITY LEVELS MAY BE INFLUENCED IN A FEW DAYS BY THE INTERPLANETARY EFFECTS FROM A SPATE OF CORONAL MASS EJECTIONS.
