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 146 publicerat klockan 2200Z på 26 May 2003IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity was at moderate levels. Region 365
(S06W06) produce two M-class events with the largest one an M1.9/1f
at 0550Z. This region also produced a long duration C7 flare at
1744Z. LASCO C2 imagery indicates narrow CME's associated with the
two M-class events but neither one has an Earth directed component.
Region 365 continues to grow in area coverage but the rate of growth
has slowed since yesterday.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 365 is expected to produce C-class
flares and has the potential for isolated M-class events.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was at quiet to active levels. Residual
effects from a high speed stream produced active conditions.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to minor storm levels. A coronal hole
high speed stream is expected to produce minor storming on day one
and day two of the period. By day three, conditions are expected to
at quiet to unsettled.
