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 288 publicerat klockan 2200Z på 14 Oct 2000IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity has been moderate. Region 9182 (N04W90)
produced an M1/Sf flare at 14/0840 UTC, as well as several C-class
subfaint flares. Region 9194 (S12E36) exhibited some increased
activity today, also producing several C-class subfaint flares.
Single flares of similar magnitude were noted from a few other
regions, including newly numbered Region 9198 (S30E65).
IB. Prognos för solaktivitet
Solar activity is expected to become
predominantly low, with the departure of Region 9182 behind the
western limb. A chance of isolated moderate-level activity remains
for regions 9194, 9193 (N05W46), and for new regions expected
on the eastern limb.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field varied from unsettled to major storm levels,
due to a prolonged period of negative Bz accompanied by moderate
solar wind speed. Greatest activity occurred during 14/0900-1800
UTC, which saw two periods of storming at minor levels in middle
latitudes, and at major levels in higher latitudes. Possible sources
of this activity include extended effects of the 09 October CME
passage, which commenced yesterday, or trailing effects from a weaker
LDE C-flare that occurred about 30 hours after the CME.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to ease to unsettled levels, with isolated active periods.
The current geomagnetic disturbance is expected to end during day
one, and an onset of high speed stream effects from a coronal hole
is expected to emerge thereafter, persisting through day two and
tapering off during day three. Isolated minor storming at higher
latitudes is possible during this period.
