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 082 publicerat klockan 2200Z på 23 Mar 2011IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z Solar activity increased to moderate levels. Region
1176 (S15E58) produced an isolated impulsive M1 flare at 23/0217Z
associated with weak radio emission. It also produced occasional B-
and C-class flares. Region 1176 rotated more fully into view and was
classified as an Eko-type group with a moderately complex beta-gamma
magnetic configuration. Region 1175 (N11W76) was quiet and stable as
it approached the west limb. New Region 1177 (N21E51) was numbered
as a magnetically simple, single-spot Axx-type.
IB. Prognos för solaktivitet
Solar activity is expected to be at
mostly low levels during the period (24 - 26 March) with a chance
for an isolated M-class flare from Region 1176.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
Geomagnetic field activity was at quiet to unsettled levels, with a
brief interval of active levels detected at Boulder at around
23/0700Z. ACE solar wind data indicated the increased activity was
the result of a coronal hole high-speed stream. Solar wind
velocities gradually increased from 358 to 547 km/sec during the
period. IMF Bt increased during the period with a maximum of 11 nT
observed at 23/0714Z. IMF Bz was variable during the period and
ranged from -6 to +8 nT.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (24 -
25 Mar) with a chance for brief active levels as coronal hole
effects persist. Activity is expected to decrease to quiet levels on
day 3 (26 March) as coronal hole effects subside.
