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 089 publicerat klockan 2200Z på 30 Mar 2005IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity was at very low levels today. Region
745 (N12W68) continues to show signs of decay. There is a single
AXX alpha spot remaining visible in white light. No significant
activity was observed on the disk or limbs during the period. No
new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low levels.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field was at predominantly quiet to unsettled levels.
Active conditions were observed following a sustained southward Bz
between 30/0600 and 0900Z. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels. Isolated active to
minor storm conditions are possible on 2 April due to the onset of a
recurrent high speed coronal hole stream.
