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 114 publicerat klockan 2200Z på 24 Apr 2005IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity continues at very low levels. There are
currently no sunspots on the visible disk. Occasional B-class flares
were associated with activity in a new region rotating on the east
limb near S05. This region was the likely source of CME activity on
22 April.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low. The new region rotating on the southeast limb may
elevate activity levels.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was quiet to unsettled with isolated active
periods. A weak recurrent coronal hole high speed stream continues.
Solar wind speed is elevated to near 550 km/s, but the IMF Bz is
weak and predominantly northward.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods on 25
April. Expect mostly quiet conditions on 26 and 27 April as the
current high speed solar wind stream subsides.
