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 285 publicerat klockan 2200Z på 11 Oct 2012IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity was low. Region 1589 (N12E49) was
responsible for the largest flare of the period; a C4 x-ray flare at
11/0804Z. Region 1589 is currently the most complex region with a
Beta-Gamma magnetic classification. New Region 1590 (S29E59)
rotated onto the southeast limb and was numbered today. No
Earth-directed coronal mass ejections were observed.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a chance for isolated M-class activity for the forecast period
(12-14 October).
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
The geomagnetic field was quiet. Solar wind speed, measured at the
ACE spacecraft, was slightly elevated between approximately 440 to
500 km/s while the Bz component of the interplanetary magnetic field
did not vary much beyond +/- 4 nT. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels throughout the
period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly quiet on days 1-2 (12-13 October). On day 3
(14 October) a coronal hole high speed stream is expected to move
into geoeffective position causing quiet to unsettled conditions
with a chance for active periods.
