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 214 publicerat klockan 2200Z på 01 Aug 2004IA. Analys av solfläcksgrupper och solaktivitet från 31-2100Z till 01-2100Z Solar activity decreased to very low levels today.
Region 654 (N08W41) produced several lower level B-class flares
today with continued decay to the groups total spot area. Region
655 (S09E44) also produced lesser B-class flares and showed a slight
increase in spot cluster area measurements. No new regions were
numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low to low levels. Region 655 has the potential to produce
isolated C-class flares.
IIA. Sammanfattning av geofysisk aktivitet 31-2100Z till 01-2100Z
The geomagnetic field ranged from quiet to active levels. A shock
passage was observed by the ACE spacecraft at approximately
01/0130Z. This transient is believed to be the result of the long
duration C2 x-ray flare that peaked at 29/1304Z from Region 652
while it was exiting the west limb. The Bz component of the
interplanetary magnetic field went south for a brief period of time
allowing for observed active periods between 01/0130 and 0300Z. The
greater than 2 MeV electron flux at geosynchronous orbit decreased
to high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels throughout the forecast
period.
