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 302 publicerat klockan 2200Z på 29 Oct 2011IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z Solar activity was low. There were five, low level
C-class flares during the past 24 hours. The largest of these was a
C3 at 1452Z from Region 1324 (N12W85). Two of the C-flares appeared
to originate from a region on the east limb at about 10 degrees
North. Region 1330 (N07W22) continues to be the largest group on the
disk at this time but was quiet and stable. A slow CME was observed
off the northeast limb late in the period but STEREO observations
indicated that this was a back-sided event.
IB. Prognos för solaktivitet
Solar activity is expected to be low.
There is a slight chance, however, for an isolated M-class flare.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
The geomagnetic field was quiet.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be generally unsettled with a chance for isolated active
periods for the next two days (30-31 October). The increase is
expected due to a high speed stream from a coronal hole. Quiet
levels are expected to prevail on the third day (01 November).
