Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 325 Välja antud 2200Z kuni 21 Nov 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 20-2100Z kuni 21-2100Z Solar activity has been high. Regions 507 (N09E36) and
508 (S18E47) produced several C-class flares, and Region 501
(N04W32) produced an M5.8/2b at 20/2354 UTC. A CME was observed on
LASCO associated with the M5 flare, although it was not directed at
the earth. No significant developments were observed with any
active region on the visible disk. No new regions were numbered
today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate to high. Regions 501, 507, and 508 are capable of
producing major flares.
IIA. Summaarne geofüüsikaline aktiivsus 20-2100Z kuni 21-2100Z
The geomagnetic field began the period at major storm levels due to
the remaining effects of a CME arrival early on 20 November.
Activity diminished to unsettled levels by the end of the period.
The greater than 10 MeV proton flux at geosynchronous orbit climbed
steadily during the period, and ended the period near the 10 pfu
threshold.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at unsettled to active conditions. Isolated minor
storm conditions on 22 November may be caused by a CME shock arrival
originating from the M9 flare observed on 20 November. Isolated
minor storm conditions are also possible on 23 November due to the
effects of high speed solar wind streams associated with a coronal
hole moving into geoeffective position.
