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 097 publicerat klockan 2200Z på 06 Apr 2004IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity has been moderate. Region 588 (S15E14)
produced an M2.4/Sf flare at 06/1328 UTC. A full-halo CME was
observed on LASCO imagery erupting from the sun shortly after the
flare, with an estimated speed of 1050 km/s. The CME was not
directed towards Earth, but may provide a glancing blow to the
geomagnetic field. No significant development was observed from
active regions on the visible disk, and no new regions were numbered
today.
IB. Prognos för solaktivitet
Solar activity is expected to be low.
Region 588 may produce C- and isolated M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
The geomagnetic field has been at quiet to minor storm conditions.
After increasing early in the period, the solar wind speed has
leveled off at about 575 km/s. The greater than 2 MeV electrons
hovered at the high threshold for most of the day, and ended the
period below the threshold.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to active conditions all three days under
the continued influence of a high speed solar wind stream associated
with a coronal hole in geoeffective position. Minor storm
conditions are expected on day two (8 April) due to the potential
effects from two recent CMEs. Although neither appeared to be
directed toward Earth, the CME associated with the M1.7 flare that
occurred on 5 April and the CME associated with today's M2.4 flare
should both arrive early on 8 April and may come close enough to
Earth's geomagnetic field to cause minor storming.
