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 05 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 064 Issued at 2200Z on 05 MAR 1997IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z SOLAR ACTIVITY REMAINED VERY LOW. HOWEVER, SEVERAL
SMALL B-CLASS X-RAY BURSTS OCCURRED. IT IS LIKELY THESE BURSTS WERE
FROM A REGION ABOUT TO ROTATE ONTO THE DISK NEAR N04. ACTIVE SURGING
AND BRIGHT KNOTS OF H-ALPHA EMISSION WERE OBSERVED OVER THIS AREA.
IB. Solar Activity Forecast
SOLAR ACTIVITY SHOULD REMAIN AT VERY
LOW LEVELS. THERE IS A POSSIBILITY OF C-CLASS EVENTS FROM THE REGION
BEYOND THE NORTHEAST LIMB. A BETTER ASSESSMENT OF FLARE POTENTIAL
CAN BE MADE ONCE THE SUNSPOT GROUP APPEARS.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
THE GEOMAGNETIC FIELD WAS QUIET UNTIL NEAR 05/1630Z. AFTER THAT TIME,
GENERALLY UNSETTLED TO ACTIVE CONDITIONS WERE OBSERVED WITH ISOLATED
MINOR STORMING OBSERVED AT A FEW HIGH LATITUDE SITES. RECENT SOLAR
WIND DATA SHOW INCREASING DENSITY AND VELOCITY. THE SOURCE OF THIS
DISTURBANCE IS UNKNOWN. ENERGETIC ELECTRON FLUXES WERE HIGH FOR MOST
OF THE PERIOD BUT DROPPED TO MODERATE LEVELS AFTER 05/1930Z.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
FORECAST TO BE PREDOMINANTLY QUIET TO UNSETTLED FOR THE NEXT THREE
DAYS. ISOLATED ACTIVE CONDITIONS ARE POSSIBLE DURING 06 MAR.
