Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 073 publicerat klockan 2200Z på 14 MAR 1998IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z SOLAR ACTIVITY WAS LOW. REGION 8173 (S18W96) PRODUCED A
C5/SF AT 13/2108Z AS IT ROUNDED THE WEST LIMB. AN ASSOCIATED CME WAS
OBSERVED BUT MATERIAL APPEARS TO BE MOSTLY WESTWARD DIRECTED. REGION
8179 (S22E09) EXHIBITED IMPRESSIVE GROWTH IN THE PAST 24 HOURS AND
IS NOW A D-TYPE SPOT GROUP WITH MODERATE MAGNETIC COMPLEXITY. SPOT
COUNT WENT FROM 12 TO 38 IN JUST 12 HOURS. THIS REGION PRODUCED
NUMEROUS SUBFLARES THIS PERIOD, MOST WITH HIGH B OR LOW C-CLASS
X-RAYS. REGION 8176 DECAYED SLIGHTLY AND IS NOW A 15 SPOT E-TYPE
GROUP. REMAINING REGIONS WERE QUIET.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. AT ITS PRESENT GROWTH RATE, REGION 8179 WILL QUICKLY
DEVELOP POTENTIAL FOR M-CLASS ACTIVITY.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REMAINED HIGH.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED.
