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 080 publicerat klockan 2200Z på 21 Mar 2003IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z Solar activity has been low. Two C class flares were
produced by Region 314 (S13W94) as it crossed the west limb. A 13
degree filament near N12E59 disappeared at about 0930 UTC, followed
by a narrow CME on the northeast limb. Another filament erupted
near S24E12 at 0948 UTC. Solar X-ray images indicate a new solar
active region near S14 behind the east limb.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to very low.
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
Geomagnetic activity has ranged from quiet to minor storm levels.
High speed solar wind and strong interplanetary magnetic field
conditions led to minor storm activity from 0000 to 1200 UTC.
Activity decreased to active levels from 1200 to 1500 UTC, and
unsettled thereafter. Greater than 2 MeV electron flux levels were
high during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be unsettled with isolated active periods during the
next 24 hours due to persistence. Conditions should decline to
mostly unsettled during the second and third days.
