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 053 publicerat klockan 2200Z på 22 FEB 1998IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z SOLAR ACTIVITY INCREASED TO LOW LEVELS WITH A OPTICALLY
UNCORRELATED C-CLASS X-RAY BURST DETECTED LATE IN THE PERIOD. REGION
8156 (S25W89) WAS STABLE AS IT APPROACHED THE WEST LIMB. 8158
(S20W69) GREW FROM PLAGE TO A SMALL B-CLASS GROUP AS SEVERAL SPOTS
EMERGED. NEW REGION 8163 (S22W28), A SMALL B-CLASS GROUP, WAS
NUMBERED. FURTHER ANALYSIS OF THE CORONAL MASS EJECTION (CME)
DESCRIBED IN YESTERDAY'S REPORT INDICATED THE CME WAS LIKELY
NON-EARTH DIRECTED.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW. HOWEVER, THERE IS A FAIR CHANCE FOR A C-CLASS FLARE FROM REGION
8156 AS IT ROUNDS THE LIMB TOMORROW.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES. THE GREATER THAN 2
MEV ELECTRON FLUX REACHED HIGH LEVELS LATE IN THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET THROUGH 23 FEBRUARY. ACTIVITY IS FORECAST TO
INCREASE DURING 24 - 25 FEBRUARY WITH MOSTLY UNSETTLED CONDITIONS
EXPECTED.
