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 030 publicerat klockan 2200Z på 30 Jan 2001IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity has been low. The largest event of the
day was an optically uncorrelated C3 flare at 30/0055 UTC. Three
new regions were numbered today: 9330 (N24E67), 9331 (N13E27), and
9332 (N08E24). Region 9330 has produced some low-level subfaint
C-class activity as it rotated into view on the east limb. Regions
9331 and 9332 both emerged with rapid development (currently in
Dao-Beta and Cso-Beta configurations, respectively) but have yet to
produce significant flare activity.
IB. Prognos för solaktivitet
Solar activity is expected to be low,
with a chance for isolated moderate-level activity from the newly
numbered regions described above, as well as Region 9321 (S06W51),
which remains the largest active region on the disk.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field has been quiet, with an isolated unsettled
period observed during 30/0300-0600 UTC. The greater-than-10 MeV
proton event, in progress at the end of last period, ended at
30/0035 UTC.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be at quiet to unsettled levels, until the anticipated
shock arrival from the CME activity observed on January 28.
Originating event characteristics, associated proton event,
interplanetary particle data profiles from the ACE EPAM instrument,
and predictive model results are all consistent with a likely shock
passage at earth within the next day or so. Active and isolated
minor storming levels are more likely in the geomagnetic field
thereafter, on January 31 and into February 1. Diminished activity
to predominantly unsettled levels are expected by February 2.
