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 309 Välja antud 2200Z kuni 04 Nov 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 03-2100Z kuni 04-2100Z Solar activity was low. Only several minor C-class
events were observed. The SOHO/LASCO imagery indicates a weak full
halo earth-directed CME occurred from a long duration C3/sf
yesterday at approximately 03/2000Z. The C3 event was produced by
Region 9213 near disk center at the time. Moderate decay was
observed in Region 9212 (N09W20) since yesterday. New Region 9221
(S15E75) was numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate.
IIA. Summaarne geofüüsikaline aktiivsus 03-2100Z kuni 04-2100Z
The geomagnetic field ranged from quiet to minor storm. A shock was
observed at the ACE spacecraft at L1 at approximately 04/0130Z. A
sudden impulse occurred at 04/0222Z (12 nT, as measured by the
boulder USGS magnetometer). Unsettled to minor storm conditions
were observed following the shock arrival. This shock is presumed
to be related to the full halo CME back on 1 November. The greater
than 10 MeV proton flux at geosynchronous orbit also briefly became
enhanced near the time of the sudden impulse.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be unsettled to active during the first day of the
period. Minor storm levels are possible in the higher latitudes.
Active conditions may continue on the second day due to the expected
arrival of the weak full halo CME on 03 November mentioned above in
1a. By the third day conditions are expected to return to
predominantly quiet to unsettled. A high-speed coronal hole stream
may also help keep activity levels unsettled throughout the period.
