SDF Number 183 Issued at 2200Z on 02 JUL 1998

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

SOLAR ACTIVITY WAS LOW. AN OPTICALLY UNCORRELATED C1 FLARE OCCURRED AT 02/0122Z. THE ONLY OTHER REGION TO FLARE THIS PERIOD WAS REGION 8256 (S24W19), PRODUCING A B8/SF AT 02/1242Z. REGION 8260 (S24E12) EXHIBITED FREQUENT PLAGE FLUCTUATIONS LATE IN THE PERIOD. REMAINING REGIONS HAVE BEEN STABLE OR SHOWED SOME DECAY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW. THOUGH MOST OF THE ACTIVE REGIONS HAVE STABILIZED OR DECAYED THIS PERIOD, THE POTENTIAL REMAINS FOR ISOLATED C-CLASS ACTIVITY. IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 01/2100Z TO 02/2100Z: THE GEOMAGNETIC FIELD WAS MOSTLY QUIET TO UNSETTLED WITH ONE ACTIVE PERIOD BETWEEN 02/00-03Z.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO REMAIN QUIET TO UNSETTLED. OCCASIONAL ACTIVE PERIODS ARE EXPECTED ON 4 AND 5 JULY IN RESPONSE TO THE C6/SF ON 1 JULY.
