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 093 publicerat klockan 2200Z på 03 Apr 2002IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z Solar activity remained at low levels. Several weak
C-class events occurred throughout the period. Most flare activity
was optically uncorrelated, however Regions 9887 (N02W02) and 9888
(S13E07) were both observed to produce C1/Sf events. New Region
9893 (N18E78) rotated into view and was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate for the next three days.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
The geomagnetic field was quiet to active. A single active period
was observed during 03/0300-0600 UTC, as coronal hole effects
diminished, and quiet to unsettled conditions predominated
thereafter. The greater than 2 MeV electron flux at geosynchronous
orbit showed moderate enhancement today, but remained below event
threshold.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled. Moderate to high flux of greater
than 2 MeV electrons at geosynchronous orbit is possible for the
duration of the forecast period.
