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 357 publicerat klockan 2200Z på 23 Dec 2014IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C5 event observed at
22/2225Z from Region 2241 (S10W47). 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 day one (24 Dec) and likely to be
moderate with a slight chance for an X-class flare on days two and three
(25 Dec, 26 Dec).
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
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
542 km/s at 23/1036Z. Total IMF reached 34 nT at 23/1040Z. The maximum
southward component of Bz reached -15 nT at 23/2001Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 14 pfu at
23/1115Z.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (24 Dec), quiet to
unsettled levels on day two (25 Dec) and quiet levels on day three (26
Dec). Protons have a slight chance of crossing threshold on day one (24
Dec) and have a slight chance of crossing threshold on days two and
three (25 Dec, 26 Dec).
