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 172 publicerat klockan 2200Z på 21 Jun 2003IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z Solar activity was at low levels. Region 388 (S03W19)
produced the largest flare of the period, a C2.5/Sf that occurred at
21/1313Z along with many lesser flares during the interval. This
region showed rapid growth during the period with a more than
doubling of the penumbral coverage. Region 386 (S07E04) produced
several lesser C-class flares today and has been in a steady decay
phase since yesterday. The delta magnetic structure is still intact
in the leading edge of the spot cluster. Region 387 (N18E23) was
fairly quiescent today although it still depicts a beta-gamma
magnetic complex. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Regions 386, 387, and 388 all have the
potential for producing M-class flare activity.
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
The geomagnetic field was at unsettled to minor storm levels.
Sustained periods of southward Bz along with elevated solar wind
speeds led to the occasional storming conditions. The greater than
2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to active levels. Isolated minor storm
conditions are possible throughout the period due to a recurrent
high speed coronal hole stream.
