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 211 publicerat klockan 2200Z på 30 Jul 2011IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity was high. Region 1261 (N17E22), a Dkc
spot group with a Beta-Gamma-Delta magnetic classification, produced
an impulsive M9 flare at 0209Z with an associated Tenflare. There
appeared to be no CME associated with the event in LASCO imagery.
Region 1260 (N19W09) has shown consolidation in its trailer spots
and is now classified as a Ehi spot group with a Beta magnetic
configuration. Region 1263 (N18E48) has been relatively stable and
did not produce any significant flaring during the period. New
Region 1265 (N18W41) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to continue
at low levels with the chance for M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field was quiet to active. Active periods were
likely due to a co-rotating interaction region (CIR) associated with
the onset of a coronal hole high speed stream. ACE signatures
indicate a possible weak CIR onset at approximately 0900Z on 30
July.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to active from 31 July to 01 August due to
effects from the coronal hole high speed stream. Quiet to unsettled
conditions are expected on 02 August.
