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 327 publicerat klockan 2200Z på 23 Nov 2011IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z Solar activity was low. The largest flare was a C2
at 23/1328Z from Region 1346 (S15W82). Region 1356 (N15E28) decayed
slightly in area in its intermediate spots. Three CMEs were
observed during the summary period. The first was associated with a
filament eruption in the northwestern quadrant first observed in
SDO/AIA 193 imagery at 22/1957Z. The second was first seen in
SOHO/LASCO C2 imagery at 23/0048Z which was possibly associated with
the same filament eruption. The third was first seen in SOHO/LASCO
C2 imagery at 23/0924Z which was associated with a high latitude
backside event. Further analysis of the 22/1957Z CME is ongoing to
determine the possibility of a glancing blow. The two subsequent
CMEs are not expected to be geoeffective.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a chance for M-class activity. An isolated M-class flare is
possible from Region 1356.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
The geomagnetic field was quiet.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly quiet for the next three days (24 - 26
November).
