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 103 publicerat klockan 2200Z på 13 Apr 2011IA. Analys av solfläcksgrupper och solaktivitet från 12-2100Z till 13-2100Z Solar activity was low during the past 24 hours. The
majority of the C-class activity originated from Regions 1191
(N08E56) and 1193 (N17E71). Region 1190 (N12W00) continues to be the
most complex as an Eac-type group with a beta-gamma magnetic
configuration, but has not produced much activity. Region 1193 was
numbered today as it rotated onto the east limb and is a Dao-type
group with a beta magnetic configuration.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with the chance for M-class activity increasing during the next
three days (14-16 April) as new Region 1193 continues to rotate onto
the disk.
IIA. Sammanfattning av geofysisk aktivitet 12-2100Z till 13-2100Z
The geomagnetic field was unsettled to active with major storm
periods observed at high latitudes during the past 24 hours. The
activity was the result of elevated wind speeds associated with a
coronal hole high speed stream (CH HSS).
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods on day one (14 April) due to residual effects from the CH
HSS. Mostly quiet conditions are expected for days two and three
(15-16 April) as the effects from the CH HSS wane.
