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 098 publicerat klockan 2200Z på 08 Apr 2002IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity was at low levels. Region 9901 (N19E24)
produced a C6/Sf flare at 08/0150 UTC and has doubled it's penumbral
coverage since yesterday. A C6 x-ray flare which appears to have
originated in Region 9899 (N18E46) was the largest flare of the
period, occurring at 08/2046 UTC. This region has shown slow but
steady growth today, in both magnetic complexity and penumbral
coverage. Multiple minor C-class were observed today with many
going optically uncorrelated. Region 9893 (N18E13) was quiescent
today producing no optically correlated flares although this region
has developed a weak delta magnetic spot in the trailing polarity of
the group. New Region 9903 (N19E74) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels.
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
The geomagnetic field activity was at quiet levels. The greater than
10 MeV electron flux was slightly elevated throughout the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field activity
is expected to be at predominantly quiet with occasional unsettled
conditions throughout the forecast period.
