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 006 publicerat klockan 2200Z på 06 Jan 2011IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity was at very low levels during the
period. Regions 1140 (N33W11) and 1142 (S14W32) were quiet and
stable.
IB. Prognos för solaktivitet
Solar activity is expected to remain
at predominately very low levels, with a chance for C-class
activity, during the forecast period (07 - 09 January).
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
The geomagnetic field was quiet at all latitudes. At approximately
06/1600Z, observations from the ACE satellite indicated a
co-rotating interaction region (CIR) had arrived. Increases in
density and wind velocity coupled with positive to negative
flucuations in the Bz component of the interplanetary magnetic field
were indicative of a CIR in advance of a coronal hole high speed
wind stream.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominately quiet to unsettled levels all three
days of the forecast period (07 - 09 January). Isolated active to
minor storm intervals are possible on 08 and 09 January. A recurrent
coronal hole high speed stream has rotated into a geoeffective
position and is expected to influence Earths magnetic field during
the period.
