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 007 publicerat klockan 2200Z på 07 Jan 2008IA. Analys av solfläcksgrupper och solaktivitet från 06-2100Z till 07-2100Z Solar activity was low. Region 980 (S06W03) produced a
C1 x-ray flare today at 1527Z. The group appears to be re-emerging
but is still small and simple. An eruptive event was observed near
plage Region 981 (N27W17) at about 0230Z and was associated with a
B1 x-ray event as well as a small CME observed by the COR2
coronagraph on the STEREO-B spacecraft.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low for the next three days (08-10 January).
IIA. Sammanfattning av geofysisk aktivitet 06-2100Z till 07-2100Z
The geomagnetic field was predominantly unsettled to active during
the past 24 hours. Solar wind speed remained elevated throughout the
day due to the continuing influence of a high speed stream. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly unsettled with a chance for isolated active
periods for the first day (08 January). Conditions are expected to
decline to quiet to unsettled for the second day (09 January) and
are expected to be quiet for the third day (10 January).
