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 254 publicerat klockan 2200Z på 11 Sep 2017IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity has been at low levels for the past 24 hours.
There are currently 2 numbered sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on day one (12 Sep) and expected to be very low with a slight
chance for a C-class flare on day two (13 Sep) and expected to be very
low on day three (14 Sep).
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 668 km/s at 11/0203Z. Total IMF reached 7
nT at 10/2328Z. The maximum southward component of Bz reached -5 nT at
10/2330Z. Protons greater than 10 MeV at geosynchronous orbit reached a
peak level of 1493 pfu at 11/1145Z. Protons greater than 100 MeV at
geosynchronous orbit reached a peak level of 68 pfu at 10/2215Z.
Electrons greater than 2 MeV at geosynchronous orbit reached a peak
level of 5361 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet to active levels on day one (12 Sep), unsettled to major
storm levels on day two (13 Sep) and unsettled to minor storm levels on
day three (14 Sep). Protons are expected to cross threshold on day one
(12 Sep), are expected to cross threshold on day two (13 Sep) and are
likely to cross threshold on day three (14 Sep).
