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 062 publicerat klockan 2200Z på 02 Mar 2012IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z Solar activity reached moderate levels today. An M3/Sf
flare was observed off the NE limb at 02/1746Z near N16. As the
region rotates on the visible disk, a more detailed analysis of its
complexity can be determined. STEREO B EUVI 195 imagery indicated a
possible CME associated with the event beginning at 02/1746Z,
however, further imagery from SOHO/LASCO will be needed to confirm.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with M-class activity likely from the new region rotating onto the
NE limb.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field was quiet to active with an isolated minor
storm period observed at high latitudes during the period 02/1200 -
1500Z. Activity was due to sustained periods of southward Bz of the
interplanetary magnetic field coupled with an elevated solar wind
speed around 450 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels during the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to continue at quiet to unsettled conditions on day 1 (03
March). Mostly quiet conditions are expected on day 2 (04 March).
A recurrent coronal high speed stream is expected increase
conditions to quiet to unsettled levels on day 3 (05 March).
