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 066 Issued at 2200Z on 07 MAR 1998

IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z

SOLAR ACTIVITY WAS LOW, BASED ON A SINGLE UNCORRELATED C1 FLARE AT 07/0231Z. NEW REGION 8175 (N44E56), A 2-SPOT 'AXX' GROUP, WAS NUMBERED TODAY. OF THE THREE ACTIVE REGIONS CURRENTLY ON THE VISIBLE DISK, REGION 8174 (S17E37) IS THE MOST COMPLEX AS A 7-SPOT 'DRO' BETA.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW TO LOW.
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
THE GEOMAGNETIC FIELD HAS BEEN MOSTLY QUIET FOR THE PAST 24 HOURS, EXCEPT FOR A SINGLE PERIOD OF UNSETTLED CONDITIONS RECORDED DURING THE INTERVAL 07/0600-0900Z.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY QUIET FOR THE NEXT THREE DAYS.
