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 292 publicerat klockan 2200Z på 19 Oct 2010IA. Analys av solfläcksgrupper och solaktivitet från 18-2100Z till 19-2100Z Solar activity was at low levels. Region 1112 (S20W70)
produced a few C-class events during the period, the largest a
C1.3/Sf at 19/0651Z. Regions 1113 (N17W03) and 1115 (S29E13) each
produced moderate-level B-class activity. Two new regions were
numbered during the period. Region 1117 (N25E74) rotated onto the
disk as a large H-type spot group while Region 1118 (N16E61) formed
on the disk as a simple uni-polar spot group.
IB. Prognos för solaktivitet
Solar activity is expected to be at
predominately very low levels with a chance for C-class activity all
three days of the period (20 - 22 October). A slight chance for
M-class activity exists from Region 1112 on 20 October as the region
approaches the west limb.
IIA. Sammanfattning av geofysisk aktivitet 18-2100Z till 19-2100Z
The geomagnetic field was at quiet to unsettled levels as a weak
coronal hole wind stream moved into a geoeffective position.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be quiet to unsettled, with a chance for isolated active
periods, on days one and two (20 - 21 October) due to continued
coronal hole high-speed stream effects. By day three (22 October),
mostly quiet levels are expected.
