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 040 publicerat klockan 2200Z på 09 Feb 2004IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z Solar activity decreased to low levels today. Region
554 (S08E52) produced numerous B and C-class flares today. Ten
C-class flares were recorded with the largest being a C9 x-ray event
that occurred at 09/1102Z. LASCO imagery has shown little, if any
associated CME signatures during the past 24 hours of activity from
this region. Magnetic analysis depicts a delta configuration within
the dominant intermediate spot. Region 551 (S06W27) did not manage
any flare production during the interval, although surging and point
brightenings were observed throughout the period. The gamma
structures in the central and trailing portions of the sunspot group
remain intact. Region 555 (S14E72) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Regions 551 and 554 both have the potential
to produce M-class flare activity.
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron fluxes at geosynchronous orbit reached high
levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels. 12 February may
experience active conditions due to a solar sector boundary
crossing, preceding an anticipated recurrent high speed coronal hole
stream.
