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 034 publicerat klockan 2200Z på 03 Feb 2010IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z Solar activity was very low. Region 1043 (N25W18)
remains stable and has not produced any significant activity within
the past 24 hours. The return of old Region 1040 is evident in EIT and SXI imagery. A CME was observed off the northeast limb at about 03/0500Z and was associated with a B1 long duration X-ray event between 0450-0700Z. A second CME that appears earthward directed was observed on both Stereo A and B. There are two coronal holes visible on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low with only a slight chance for a C-class flare.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
The geomagnetic field was generally unsettled with an active period from 02/2100Z-03/0000Z. Solar wind speeds were elevated throughout the period with peak velocities around 580 km/s.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet for the next two days (04-05 February). An increase to mostly unsettled levels is expected in the third day (06 February) in response to a high speed stream.
