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 089 Välja antud 2200Z kuni 30 Mar 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity has been moderate to high. Region 9393
(N17 W30) has produced three M-class flares since 30/0000 UTC. The
region remains large, complex, and threatening to produce more Class
X events.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to remain
high. Region 9393 remains the center of a complex likely to
produce M-Class events with a very good chance of one or more Class
X events over the next three days as the region moves away from
central meridian but remains in a prime location to produce strong
to severe effects at Earth. Over a dozen sunspot groups are
visible and may produce Class M events.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
Activity in the geomagnetic field has been unsettled the past 24
hours. Some discontinuity was observed at the ACE spacecraft and at
Earth between 30/1800 UTC and 30/1900 UTC. The event appeared to be
small and is likely the result of solar activity prior to 29 March.
The small proton event that began at 29/1000 UTC reached a
maximum flux of 35 pfu in the >30 MeV GOES detector and remains
above 10 pfu today.
IIB. Geofüüsikalise aktiivsuse ennustus
Effects from CME's from the
events on 29 March are expected to begin early on 31 March. Model
runs predict an earlier arrival at Earth late on 30 March. ACE
energetic protons are rising slowly indicating the disturbance is
still some distance away at 30/2100 UT. Any geomagnetic storm that
results is expected to range from minor to major. The small >30 MeV
proton event in progress is expected to continue its slow decline
with a chance of an enhancement with the passage of the
interplanetary shock. Major activity from Region 9393 may well
produce additional proton events and geomagnetic activity at Earth.
