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 142 publicerat klockan 2200Z på 22 May 2013IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M5 event observed at
22/1332Z from Region 1745 (N13W80). There are currently 7 numbered
sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (23 May, 24 May, 25 May).
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
500 km/s at 22/0442Z. Total IMF reached 6 nT at 22/2005Z. The maximum
southward component of Bz reached -5 nT at 21/2357Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 279 pfu at
22/2035Z. Protons greater than 100 MeV at geosynchronous orbit reached a
peak level of 3 pfu at 22/1830Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 722 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at unsettled to active levels on day one (23 May), quiet to
unsettled levels on day two (24 May) and quiet to active levels on day
three (25 May). Protons are expected to cross threshold on days one and
two (23 May, 24 May) and are likely to cross threshold on day three (25
May).
