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 005 publicerat klockan 2200Z på 05 Jan 2008IA. Analys av solfläcksgrupper och solaktivitet från 04-2100Z till 05-2100Z Solar activity was very low. No flares were observed
during the past 24 hours. Region 981 (N29E14) is currently the only
spotted region on the disk but is quiet and stable.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low.
IIA. Sammanfattning av geofysisk aktivitet 04-2100Z till 05-2100Z
The geomagnetic field was initially quiet but after 0600Z became
predominantly unsettled to active with isolated minor storming in
some locations. Real-time solar wind observations showed a marked
increase in velocity, magnetic field and temperature at about
04/2330Z, and then again at 05/0600Z. The signatures are most
consistent with a high-speed stream from a coronal hole, although
there may have been some complicating influence from the interaction
of recent transient activity with the stream.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly unsettled to active for the next two days
(06-07 January) due to ongoing persistence from the high speed
stream. Activity is expected to subside somewhat on the third day
(08 January) as the stream should be declining at that time.
