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 088 publicerat klockan 2200Z på 29 MAR 1998IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z SOLAR ACTIVITY WAS VERY LOW. THERE HAS BEEN LITTLE
ACTIVITY FROM ANY OF THE FIVE SPOTTED REGIONS ON THE DISK. OPTICALLY
UNCORELATED TYPE II AND TYPE IV SWEEP FREQUENCY BURSTS WERE OBSERVED
TODAY. THE TYPE II WAS AT 29/0245Z WITH A SHOCK SPEED OF 600 KM/S
AND THE TYPE IV WAS OBSERVED FROM 29/0302Z-29/0332Z. A 27 DEGREE
LONG FILAMENT POSITIONED IN THE NW DISAPPEARED YESTERDAY BETWEEN
28/1826Z-28/2038Z. THE SOHO/LASCO INSTRUMENT OBSERVED A LARGE
PARTIAL HALO/CME AT ABOUT 29/0348Z. THE MATERIAL MAY HAVE ORIGINATED
ON THE BACK-SIDE OF THE DISK. A NEW REGION WAS NUMBERED TODAY AS
REGION 8190 (S20E66).
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE VERY LOW TO
LOW THROUGH THE PERIOD. REGION 8185 STILL HAS THE POTENTIAL FOR
PRODUCING AN ISOLATED M-CLASS EVENT.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ALTITUDE WAS HIGH.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD BE
PRIMARILY QUIET TO UNSETTLED FOR THE NEXT THREE DAYS WITH PERIODS OF
ACTIVE CONDITIONS AT ALL LATITUDES.
