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 067 Issued at 2200Z on 08 MAR 1997

IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z

SOLAR ACTIVITY WAS VERY LOW. REGION 8020 (N06E48) WAS VERY QUIET AND STABLE. A NEW REGION 8021 (S30E42) EMERGED ON THE DISK TODAY AS A SIMPLE AXX TYPE SUNSPOT GROUP. A REMARKABLE FEATURE WAS VISIBLE ON THE SOHO EUV HEII IMAGE AT 1014Z TODAY. THE FEATURE WAS VISIBLE OVER THE NORTHEAST LIMB, WAS ABOUT 0.2 SOLAR RADII IN LENGTH, AND HAS THE APPEARANCE OF A PROMINENCE ERUPTION.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT MID-LATITUDES AND WAS QUIET TO UNSETTLED AT HIGH LATITUDES.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE PREDOMINANTLY UNSETTLED FOR THE NEXT TWO DAYS. AN INCREASE TO UNSETTLED TO ACTIVE LEVELS IS EXPECTED ON THE THIRD DAY IN RESPONSE TO A FAVORABLY POSITIONED CORONAL HOLE.
