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 115 publicerat klockan 2200Z på 25 Apr 2001IA. Analys av solfläcksgrupper och solaktivitet från 24-2100Z till 25-2100Z Solar activity has been moderate. Region 9433 (N16W15)
produced two M-class flares during the period. The largest was an
M2/2n at 25/1348 UTC. This event had an associated Type II radio
sweep and a 200 sfu 10 cm radio burst. A coronal mass ejection (CME)
was also observed during this event, however images from the
LASCO/EIT space craft show it to be non earth-directed. Region 9433
continued to grow in area and spot count during the period and
retains an F-type spot group with a beta-gamma-delta magnetic
configuration. Regions 9438 (S13E22) and 9439 (S22W28) were numbered
during the period.
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate to high. The ongoing development of Region 9433 suggests a
major flare is possible sometime during the forecast period.
IIA. Sammanfattning av geofysisk aktivitet 24-2100Z till 25-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to remain at quiet to unsettled conditions barring an
earth-directed CME. There is an increasing chance for a proton event
as Region 9433 continues to evolve and rotate into the western solar
hemisphere.
