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 035 publicerat klockan 2200Z på 04 Feb 2003 IA. Analysis of Solar Active Regions and Activity from 03/2100 UTC to 04/2100 UTC: Solar activity was at low levels during the past 24 hours. Region 278 (N20E81) produced the only C-flare, a C1.4 at 04/2016 UTC. Region 276 (S13E45) continues to be the largest region on the disk with an area of 260 millionths and fairly continuous point brightenings. New regions 277 (S19E70) have produced several B-class flares, and show continual activity.IB. Prognos för solaktivitet
Solar activity is expected to be
low to moderate. Regions 276, 277, and 278 have potential for M-class flare activity.
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
The geomagnetic field was at unsettled to active levels during the
past 24 hours. Solar wind observations show a continuation of
yesterday's enhanced flow associated with a coronal hole structure
in the northern hemisphere. Flow should return to nominal levels in
the next 24 hours. The greater than 2 MeV electron fluxes briefly
reached high levels during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly unsettled tomorrow, with a chance for some
isolated active periods later in the day. An increase to active
levels is expected for the second day due to a favorably positioned
coronal hole.
