Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 294 Välja antud 2200Z kuni 21 Oct 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 20-2100Z kuni 21-2100Z
Solar activity has been moderate. There has been a
steady series of C-class flares and a single M1.0 at 21/0827 UTC.
Region 484 (N05E26) continues to grow, but at a lesser rate than
yesterday. The region is now 1650 millionths with at least a 50%
increase in magnetic intensity. A region just beyond the East limb,
generated a strong CME at approximately 21/0300 UTC, but does not
appear to be Earth-directed.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to remain
moderate. Region 484, and the new Region approaching the East limb,
are a combined threat to continue to generate C-class activity, with
an occasional M-class flare. There is a slight chance for an
isolated X-class event, and an even lesser chance for a
proton-producing flare. By day three, Region 484 will near central
meridian, and become a slightly higher threat for producing a flare
event which could generate protons at near-Earth.
IIA. Summaarne geofüüsikaline aktiivsus 20-2100Z kuni 21-2100Z
The geomagnetic field has been at active to minor storm levels. A
favorably positioned coronal hole is supporting a high-speed solar
wind stream, which is in turn supporting elevated magnetic activity
at Earth. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at active to minor storm levels for the next three
days. The coronal hole will proceed out of geoeffective range
around the second day, but a faint shock associated with a CME which
occurred on the 19th should lightly impact Earth, once again
elevating magnetic activity on day three.
