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 129 publicerat klockan 2200Z på 09 May 2005IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z Solar activity was low. Region 758 (S09W23) produced
five C-class flares during the past 24 hours. The largest of these
was a C8 at 1103 UTC. The region has shown steady development during
the past 24 hours, especially in the leader spots. New Region 760
(S06W14) has been identified as a distinct region to the east of
758. Region 759 (N14E60) is the largest group on the disk with area
of 540 millionths but only managed to produce a B-class event. New
Region 761 (N04E61) was assigned today and is a small, H-type group.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate during the next three days (10-12 May). There is a fair
chance for isolated M-class events from Region 758 or Region 759.
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
The geomagnetic field was unsettled to active for 08/2100-08/2400
UTC. Unsettled levels prevailed from 08/2400-09/0600 UTC, and
conditions were quiet for the remainder of the period. Solar wind
data show a steady decline in velocity, which was initially at about
730 km/s and decreased to about 550 km/s by the end of the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled with a chance for active periods at high
latitudes for the next 24 hours (10 May). Conditions should be
mostly unsettled for 11 May and quiet to unsettled for 12 May.
