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 083 publicerat klockan 2200Z på 23 MAR 2000IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z SOLAR ACTIVITY WAS MODERATE DUE TO TWO M-CLASS EVENTS
DURING THE PERIOD. THE FIRST WAS AN OPTICALLY UNCORRELATED M1 X-RAY
FLARE AT 23/0030UT AND THE SECOND WAS AN M2/SF FROM REGION 8910 AT
23/1214UT. REGION 8910 IS THE LARGEST AND MOST ACTIVE REGION AND CAN
BE EXPECTED TO CONTINUE TO PRODUCE C AND POSSIBLE M-CLASS
EVENTS AS IT APPROACHES THE WEST LIMB. REGIONS 8913 (S06W50), 8915
(N23W14), AND 8917 (N19W47) ALL PRODUCED C-CLASS FLARES DURING THE
PERIOD. REGIONS 8916 (N13E01), 8918 (N13W66), AND 8921 (S15E37) WERE
ALSO ACTIVE, PRODUCING OPTICAL SUBFLARES DURING THE REPORTING
PERIOD. FOUR NEW REGIONS WERE NUMBERED; 8924 (N13E70), 8925
(S17E76), 8926 (S10W18), AND 8927 (N18E01).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE SOLAR WIND SPEED
REMAINED HIGH, ALTHOUGH SHOWING A SLIGHT DECREASE DURING THE PERIOD,
FROM 600 TO 500 KM/S. PRESUMABLY RELATED TO A WELL POSITIONED
CORONAL HOLE IN THE SOUTHWEST.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO ACTIVE, WITH ISOLATED MINOR STORMING
CONDITIONS POSSIBLE AT HIGHER LATITUDES DURING THE SECOND DAY OF THE
PERIOD.
