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 061 Issued at 2200Z on 02 MAR 1997IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z THE VISIBLE DISK REMAINED SPOTLESS AND SOLAR ACTIVITY
REMAINED VERY LOW.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD CONTINUE AT VERY
LOW LEVELS FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD BEGAN THE PERIOD WITH QUIET CONDITIONS.
GENERALLY ACTIVE LEVELS WERE OBSERVED FROM 02/0300-1200Z. SOME HIGH
LATITUDE SITES EXPERIENCED STORM CONDITIONS DURING THAT INTERVAL.
THE FIELD RETURNED TO QUIET CONDITIONS FOR THE REMAINDER OF THE
PERIOD. WHEN COMPARED TO 01 MAR, SOLAR WIND VELOCITY DECREASED BY
ABOUT 100 KM/S DURING THE PERIOD. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT WERE HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
FORECAST TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED
ACTIVE CONDITIONS ARE POSSIBLE DURING THAT TIME.
