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 323 publicerat klockan 2200Z på 18 Nov 2012IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C5 event observed at
18/0407Z from Region 1615 (N07W34). Consolidation and moderate growth
was observed in Region 1619 (N10E03) which occasionally displayed
beta-gamma magnetic characteristics. There are currently 8 numbered
sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be at low
levels on days one, two, and three (19 Nov, 20 Nov, 21 Nov) with a
chance for isolated moderate activity.
IIA. Sammanfattning av geofysisk aktivitet 17-2100Z till 18-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
at ACE reached 451 km/s at 18/1301Z. Total IMF reached 5 nT at 18/2028Z.
The maximum southward component of Bz remained between +/- 4 nT during
the period. A new coronal hole was identified in the southern hemisphere
near center disk. Greater than 2 MeV electron flux at geosynchronous
orbit reached a peak of 1512 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at mostly quiet levels for the next three days (19 Nov, 20 Nov, 21
Nov) with the exception of a possible unsettled period late on 19 Nov or
early on 20 Nov with the arrival of a weak coronal hole high speed solar
wind stream.
