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 064 publicerat klockan 2200Z på 04 Mar 2004IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z Solar activity was at low levels today. Region 567
(S12W29) produced multiple low level B and C-class flares throughout
the period. The largest event was a C2 x-ray flare that occurred at
04/1007Z. A weak delta magnetic structure has become evident in a
cluster of intermediate sunspots near region center. An emerging
flux region, Region 569 (S11E34) with several rapidly developing
umbra, was assigned today. The remainder of the disk and limb were
quiet today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels. Region 567 is capable of producing an isolated low
level M-class event.
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
The geomagnetic field was at quiet to unsettled levels. The high
speed solar wind stream has been on a steady decline since the
middle of the period (from 600 to near 450 km/s at the time of this
writing). The greater than 2 MeV electron fluxes at geosynchronous
orbit reached high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels throughout
the period.
