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 348 publicerat klockan 2200Z på 14 Dec 2011IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity was low. There were numerous C-class
events during the past 24 hours; the largest was a C7 at 1459Z from
Region 1367 (S18, beyond west limb). GOES SXI imagery showed that
Region 1367 was responsible for the other C-class events during the
period as well. Region 1374 (S18W11) continues to be the largest
group on the disk but was stable and quiet. New Region 1377 (N11E43)
was assigned and appears to be a small, D-type sunspot region. A
coronal mass ejection was noted from the west limb at about
14/0412Z; disk imagery indicate the source region was near the limb
and the CME is not expected to be geoeffective.
IB. Prognos för solaktivitet
Solar activity is expected to be low
for the next three days (15-17 December).
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly quiet tomorrow (15 December) but there is a
possibility for some brief unsettled periods due to a glancing blow
from the CME/DSF that occurred on 11 December. Quiet levels are
expected to prevail for 16-17 December.
