Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 152 Issued at 2200Z on 01 JUN 1998IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z SOLAR ACTIVITY WAS VERY LOW. THE TWO MAIN REGIONS: 8227
(N21W21) AND 8230 (S20E35) SHOWED VERY LITTLE CHANGE OR ACTIVITY
DURING THE DAY. BOTH REGIONS HAVE "DSO-BETA" SPOT GROUPS. REGION
8227 PRODUCED A SF AT 01/0700Z WITH NO CORRELATED X-RAY ACTIVITY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
ISOLATED C-CLASS FLARES ARE POSSIBLE FROM REGIONS 8227 AND 8230.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z

AT GEOSYNCHRONOUS ORBIT EXCEEDED THRESHOLD LEVEL OF 1000PFU AT
01/1530Z AND HAS REMAINED ELEVATED FOR THE REST OF THE REPORTING
PERIOD.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET.
