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 120 publicerat klockan 2200Z på 30 Apr 2005IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity was low. Region 756 (S07E01) produced a
C1/Sf flare at 30/1824 UTC. Region 756 continues to increase in
area; however, this region has only managed to produced lower level
C-flares. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a chance for an isolated M-flare from Region 756.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field was unsettled to active with an isolated minor
storm period between 30/0000 UTC and 0300 UTC. Heightened activity
was due to the onset of a geoeffective coronal hole high speed
stream. Solar wind speed at ACE increased from approximately 380
km/s to 600 km/s.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to active with minor storm periods possible
on 01 May. Conditions are expected to settled down to quiet to
unsettled levels with active periods possible for the remainder of
the period.
