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 060 publicerat klockan 2200Z på 01 Mar 2011IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 01-2100Z Solar activity has been low. Occasional C-class x-ray
flares occurred throughout the period, the largest of which was a
C6/Sf at 01/0413Z from Region 1164 (N25E19). This region grew in
size and magnetic complexity, ending the period as an Ekc type with
Beta-Gamma-Delta magnetic characteristics. The remaining regions
were quiescent.
IB. Prognos för solaktivitet
Solar activity is expected to be low,
with an increasing chance for an M-class x-ray flare from Region
1164.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 01-2100Z
The geomagnetic field ranged from quiet to minor storm activity
levels during the period. Solar wind speed at the ACE spacecraft
began to rise from 310 km/s at approximately 01/0500Z and ended the
period near 500 km/s. The Bz component of the interplanetary
magnetic field turned south coincident with the increase in solar
wind speed, temperature, and density. These events suggest the
arrival of a corotating interaction region between 01/05-12Z in
advance of a coronal hole high speed stream. Bz averaged -10 nT
for several hours, bringing two periods of minor storm levels at
middle latitudes.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be predominantly unsettled with a chance for active
conditions over the next three days (2-4 March). A slight chance
for isolated minor storm periods exists on days one and two (2-3
March).
