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 039 publicerat klockan 2200Z på 08 Feb 2011IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity has been at low levels for the past 24
hours. Region 1153 (N15W71) has shown continued growth and was
responsible for a majority of the activity this period, including a
C1/Sf event at 08/1854Z. Several new regions were numbered today,
Region 1154 (N08W51), Region 1155 (N17E26), Region 1156 (S19E43),
and Region 1157 (N22E36). These regions all emerged early in the
period and contain simple magnetic configurations.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels for the next two days (09-10 February) as Region 1153
rotates off the west limb. Very low to low levels are expected on
day three (11 February) as the remaining regions on the disk
continue to evolve.
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
The geomagnetic field has been at predominantly quiet levels for the
past 24 hours. 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 at quiet to unsettled levels for the next two days
(09-10 February) as a weak coronal hole high-speed stream moves into
a geoeffective position. A return to quiet levels is expected on day
three (11 February).
