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 011 publicerat klockan 2200Z på 11 Jan 2011IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity remained very low with occasional
low-level B-class flares. Region 1140 (N33W74) developed a few spots
north of its main spot and was classified as a Cso-type group. It
produced a B-class flare as it approached the west limb. Region 1146
(N23E33) showed little change during the period and produced a
single B-class flare. Two B-class flares were observed on the
southwest limb and attributed to plage Region 1142 (S17, L=212),
which departed the visible disk early in the period.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low through the period (12 - 14 January).
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
Geomagnetic field activity was at mostly quiet levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
during the period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at mostly quiet levels during days 1 - 2 (12 - 13
January). Activity is expected to increase to quiet to unsettled
levels with a chance for brief active levels on day 3 (14 January)
as a recurrent coronal high-speed stream becomes geoeffective.
