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 255 publicerat klockan 2200Z på 11 Sep 2012IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity was at low levels. Region 1564 (S11W82)
was the most active region with several C-class flares, the largest
of which was a C6/Sf at 10/2356Z. Regions 1567 (N16W02) and 1569
(S12E53) also contributed to the C-class flare activity. Region
1567 decayed throughout the period. There was no Earth directed CME
activity during the period.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a chance for an isolated M-class flare for the first day (12
September). M-class probability is expected to decrease for the
second and third days (13-14 September) as Region 1564 rotates out
of view.
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
Geomagnetic field activity was at quiet levels throughout the period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be quiet with a slight chance for unsettled levels on
days 1 and 2 (12-13 September). An increase to quiet to unsettled
levels with a slight chance for an active period is expected on the
third day (14 September) due to a favorably positioned coronal hole.
