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 114 publicerat klockan 2200Z på 24 Apr 2003IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity was at moderate levels this period.
Region 338 (N18W45) produced an M3/1n at 24/1253Z with associated
Type II (830 km/s) and Type IV radio sweeps. A partial halo CME was
also detected on LASCO imagery. Region 339 (N16,L=337) was active
during the period, producing several C-class flares as it crossed
the west limb, the largest being a C8 flare at 24/1553Z. No
significant changes were observed in the remaining active regions.
New Regions 344 (N16E39), 345 (S17E74), and 346 (N16E74) were
numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
moderate levels. Region 338 may produce futher M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was at unsettled to active levels with isolated
minor storm periods at high latitudes. Elevated solar wind speeds
up to near 600 km/s are responsible for the disturbed periods. The
greater than 2 MeV electrons at geosynchronous orbit reached high
levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to minor storm levels. High speed
coronal hole flow may be enhanced by transient flow over the next
three days. Weak CME impact from an M5 flare on April 23 are
possible on days one and two. A CME impact produced by today's M3
flare may arrive on day three.
