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 134 publicerat klockan 2200Z på 14 May 2013IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a X3 event observed at
14/0111Z from Region 1748 (N11E63). There are currently 8 numbered
sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (15 May, 16
May, 17 May).
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
432 km/s at 14/1129Z. Total IMF reached 9 nT at 14/1806Z. The maximum
southward component of Bz reached -5 nT at 14/1128Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 213 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet to active levels on day one (15 May), quiet to unsettled
levels on day two (16 May) and quiet levels on day three (17 May).
Protons have a slight chance of crossing threshold on day one (15 May),
have a chance of crossing threshold on day two (16 May) and have a
chance of crossing threshold on day three (17 May).
