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 182 publicerat klockan 2200Z på 01 Jul 2005IA. Analys av solfläcksgrupper och solaktivitet från 30-2100Z till 01-2100Z Solar activity was low during the past 24 hours.
Today's largest event was a C5 at 0502 UTC from newly numbered
Region 786 (N13E76). The event was associated with a type II radio
sweep and a small, narrow CME off the east limb. There was one
additional C-flare today; a C1 at 1256 UTC from Region 782 (S17W18).
Region 782 and 783 (S03E33) both showed noteworthy growth during the
past 24 hours. New Region 787 (S09W22) emerged on the disk during
the day as a small B-type group.
IB. Prognos för solaktivitet
Solar activity is expected to be low
during the next three days (02-04 July), but there is a slight
chance for an isolated M-class event.
IIA. Sammanfattning av geofysisk aktivitet 30-2100Z till 01-2100Z
The geomagnetic field was mostly quiet to active, but there was a
minor storm period from 1500-1800 UTC. Solar wind data indicate the
onset of a high speed stream from a coronal hole, beginning at about
1200 UTC. Solar wind speed at the end of the analysis period had
reached about 500 km/s and was steadily increasing.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly active for the first day (02 July), with a
chance for isolated minor storm periods. Conditions should decline
to unsettled to active for the second day (03 July), and should be
predominantly unsettled for the third day (04 July).
