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 009 publicerat klockan 2200Z på 09 Jan 2011IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z Solar activity remained at very low levels. Region 1140
(N32W49) produced a B1 flare at 09/1351Z. Region 1140 showed signs
of decay with the loss of spots in the positive-polarity field just
north of the main spot and was classified as an Hsx group. The
remaining spot groups were A- and B-types with simple magnetic
configurations, including newly numbered Regions 1144 (S16W36) and
1145 (N15E35).
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low levels through the period (10 - 12 January).
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
Geomagnetic field activity remained at quiet to unsettled levels. ACE
solar wind measurements indicated Earth remained within a recurrent
coronal hole high-speed stream. Solar wind velocities were variable
in the 554 to 648 km/s range. IMF Bt showed a gradual increase with
a peak value of 6 nT observed late in the period. IMF Bz was
variable and ranged from +5 to -4 nT during the period. 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 quiet to unsettled levels during day 1 (10
January) as the coronal hole high-speed stream persists. Field
activity is expected to decrease to quiet levels during days 2 - 3
(11 - 12 January) as the high-speed stream subsides.
