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 175 publicerat klockan 2200Z på 24 Jun 2005IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity was at very low levels. Flare activity
was limited to minor B-class x-ray events seen on the solar west
limb near S19. The source region for this activity is believed to
be from old Region 779 (S19 L=332). Region 780 (S08W30) underwent
continued decay and the region has become a simple BXO beta group.
No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to remain
at very low levels.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was at quiet to minor storm levels. The storm
conditions are due to a recurrent coronal hole. The associated
solar wind speeds have been elevated to near 500 km/sec throughout
most of the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly unsettled to active levels. There
may be a slight chance of isolated minor storming conditions though
25 June due to the geoeffective coronal hole. Unsettled levels with
isolated active conditions are expected on 26 June as the coronal
hole wanes. Quiet to unsettled levels should return by 27 June.
