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 240 publicerat klockan 2200Z på 28 Aug 2002IA. Analys av solfläcksgrupper och solaktivitet från 27-2100Z till 28-2100Z Solar activity was at moderate levels. Region 90
(S04E20) produced an M4/Sf flare at 28/1859 UTC that had an
associated Type II radio sweep with an estimated shock velocity of
736 km/s. A significant Type four radio sweep and a Tenflare of 930
pfu were also associated with this flare. Region 83 (S18W84), which
is currently exiting the disk, produced an M1 flare (correlated
using SOHO/EIT imagery) at 28/1658 UTC. Region 87 (S08W07) showed
growth during the period as a delta magnetic spot became apparent in
the southeast portion of the spot group. Region 85 (S08W50) showed
a slight growth in penumbral coverage although remained fairly
quiescent during the period. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 87 has the potential to produce
M-class activity.
IIA. Sammanfattning av geofysisk aktivitet 27-2100Z till 28-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled throughout the period.
