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 136 publicerat klockan 2200Z på 16 May 2013IA. Analys av solfläcksgrupper och solaktivitet från 15-2100Z till 16-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
16/1924Z from Region 1748 (N12E36). There are currently 10 numbered
sunspot regions on the disk.
IB. Prognos för solaktivitet
Solar activity is expected to be high with
a chance for X-class flares on days one, two, and three (17 May, 18 May,
19 May).
IIA. Sammanfattning av geofysisk aktivitet 15-2100Z till 16-2100Z
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
450 km/s at 15/2326Z. Total IMF reached 7 nT at 15/2115Z. The maximum
southward component of Bz reached -6 nT at 16/0139Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 32 pfu at
16/0410Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 117 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet to active levels on day one (17 May) and quiet to
unsettled levels on days two and three (18 May, 19 May). Protons are
expected to cross threshold on day one (17 May), are expected to cross
threshold on day two (18 May) and are expected to cross threshold on day
three (19 May).
