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 164 publicerat klockan 2200Z på 12 Jun 2012IA. Analys av solfläcksgrupper och solaktivitet från 11-2100Z till 12-2100Z Solar activity was low. Regions 1506 (N11E38), 1504
(S17E28), and 1507 (S27E02) were the most active regions on the
disk. Each region was responsible for multiple C-flares during the
period. The largest of these came from Region 1506 which produced a
C2 flare at 12/0315Z. All three of these regions have shown signs
of growth. There were no Earth-directed CMEs observed during the
period.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. There is a chance for an isolated M-class event from
Region 1504.
IIA. Sammanfattning av geofysisk aktivitet 11-2100Z till 12-2100Z
The geomagnetic field ranged from quiet to minor storm levels. Minor
storm levels were reached from 11/2100Z to 12/0300Z. This was
followed by an active period from 12/0300Z to 12/0600Z. Solar wind
observations indicated a sustained interval of negative Bz from
11/1500Z to 12/0200Z with peak values around -10nT. In addition,
the data indicated a solar sector boundary crossing starting late on
the 11th.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be quiet to unsettled on day 1 (June 13). Quiet levels
are expected for 14-15 June.
