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 210 publicerat klockan 2200Z på 29 Jul 2011IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z Solar activity was low. Region 1261 (N16E33) produced
the majority of the C-class flare events. The largest was a C6/1f
at 1640Z. Region 1261 appears to be in decay and is classified as
Dai spot group with a beta-gamma magnetic configuration. Region
1260 (N19E03) appears to show separation between the leader and
trailing spots and is classified as a Eai spot group with a
beta-gamma magnetic configuration. Region 1263 (N18E59) has been
largely quiet and stable as it rotated into view, only managing a
low level C-flare.
IB. Prognos för solaktivitet
Solar activity is expected to continue
at low levels with a chance for M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
The geomagnetic field was mostly quiet. 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 be mostly quiet on 30 July. Unsettled conditions with
possible active periods are expected on 31 July-01 August due to
effects from a coronal hole high speed stream.
