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 319 publicerat klockan 2200Z på 14 Nov 2012IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
14/0404Z from Region 1613 (S23E18). Regions 1610 (S23W36) and 1611
(N13W14) have decayed and now have weak beta-gamma magnetic
complexities. Region 1613 experienced some decay in the penumbra and is
now only considered to be a simple bi-polar region. New Region 1616
(N21E61) was numbered during the period. There are currently 7 numbered
sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be at low to
moderate levels on days one, two, and three (15 Nov, 16 Nov, 17 Nov).
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 466 km/s at 14/1631Z. Total IMF reached 23 nT at 13/2226Z. The
maximum southward component of Bz reached -19.1 nT at 14/0251Z. The
increase in activity was caused by prolonged period of -Bz. A solar
sector boundary crossing appears to have occurred at around 14/0245Z
followed by a negative polarity coronal hole high speed stream (CH HSS).
Electrons greater than 2 MeV at geosynchronous orbit reached a peak
level of 267 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet to unsettled levels for the next three days (15 Nov, 16
Nov, 17 Nov) due to continued effects from the negative polarity coronal
hole followed by the onset of a positive polarity coronal hole.
