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 217 Issued at 2200Z on 05 AUG 1998

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

SOLAR ACTIVITY WAS LOW. A SINGLE UNOBSERVED C-CLASS EVENT OCCURRED AT 1615Z. REGION 8293 (S22E39) GREW IN WHITE LIGHT AND H-ALPHA, AND IS THE DOMINANT REGION ON THE DISK. IT POSSESSES A SLIGHT DEGREE OF MAGNETIC COMPLEXITY AND BRIGHT PLAGE. NEWLY NUMBERED REGION 8296 (N16E70) ROTATED FULLY INTO VIEW AS A MATURE SINGLE SPOT. THE LIMBS WERE QUIET.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW. REGION 8293 COULD RAISE ACTIVITY LEVELS OVER THE NEXT THREE DAYS IF ADDITIONAL DEVELOPMENT OCCURS THERE.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO PERSIST AT QUIET TO UNSETTLED LEVELS THROUGHOUT THE FORECAST PERIOD.
