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.
Report of Solar-Geophysical Activity 1997 Mar 24 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 083 Issued at 2200Z on 24 MAR 1997IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z
THE DISK REMAINED SPOTLESS AND SOLAR ACTIVITY CONTINUED
AT A VERY LOW LEVEL. A LARGE CORONAL MASS EJECTION WAS OBSERVED OFF
THE WEST LIMB DURING THE PERIOD (NO TIME AVAILABLE). DUE TO THE
LACK OF OBVIOUS SOURCES ON THE VISIBLE DISK, IT IS POSSIBLE THIS
EVENT ORIGINATED ON THE BACK SIDE OF THE SUN.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD CONTINUE AT A
VERY LOW LEVEL FOR THE NEXT THREE DAYS.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO SLIGHTLY UNSETTLED.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD SHOULD BE
QUIET TO UNSETTLED FOR THE FIRST PART OF 25 MAR. A RECURRENT HIGH
SPEED STREAM SHOULD BEGIN TO INFLUENCE THE FIELD LATE ON 25 MAR AND
CONTINUE TO DO SO THROUGH 27 MAR. GENERALLY UNSETTLED TO ACTIVE
CONDITIONS ARE EXPECTED DURING THAT INTERVAL. ISOLATED MINOR
STORMING IS POSSIBLE DURING THIS DISTURBANCE, ESPECIALLY AT HIGH
LATITUDES.
