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 315 publicerat klockan 2200Z på 10 Nov 2012IA. Analys av solfläcksgrupper och solaktivitet från 09-2100Z till 10-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
10/0504Z from Region 1608 (S20W03) which was also associated with a
coronal mass ejection (CME). An additional CME was observed off the west
limb at 10/1448Z but was from a region on the backside and is not
earthward directed. A new unnumbered spot region is rotating onto the
disk from east limb at about S21. There are currently 5 numbered sunspot
regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be low with
a slight chance for an M-class event on days one, two, and three (11
Nov, 12 Nov, 13 Nov).
IIA. Sammanfattning av geofysisk aktivitet 09-2100Z till 10-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 337 km/s at
09/2104Z.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be quiet with a slight chance of unsettled levels on day one (11
Nov). The CMEs from 09/1524Z and 10/0539Z are expected to merge and
arrive on 12 Nov around 1200Z which will increase geomagnetic activity
to active levels with a chance for minor storm periods on days two and
three (12 Nov, 13 Nov).
