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 162 publicerat klockan 2200Z på 11 Jun 2011IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity decreased to very low levels. Occasional
B-class x-ray flares occurred. There were three small,
simply-structured spots groups on the disk, including newly-numbered
Region 1235 (N14E27). No Earth-directed coronal mass ejections
occurred during the period.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low through the period (12 - 14 June) with a slight chance for a
C-class flare.
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
Geomagnetic activity was at quiet to active levels. Active levels
occurred during 11/0300 - 0600Z, associated with a period of
increased interplanetary magnetic field (IMF) Bt (peak 10 nT) and
southward IMF Bz (peak deflection -8 nT). ACE solar wind data
indicated a co-rotating interaction region occurred during the first
half of the period, in advance of a coronal hole high-speed stream
(CH HSS). The CH HSS commenced around 11/1025Z, followed by a
gradual increase in solar wind speeds (380 to 460 km/s) during the
rest of the period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be at quiet to unsettled levels during days 1 - 3 (12 -
14 June) with a chance for brief active periods due to CH HSS
effects.
