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 092 Välja antud 2200Z kuni 02 Apr 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z Solar activity continued at low levels. The largest
event of the period was an optically uncorrelated C9.4 flare at
02/0050 UTC. No resulting CME activity was apparent in available
imagery from SOHO/LASCO. Region 9887 (N02E11) was a dominant source
of numerous, lesser C-class flares throughout the period. This
region has grown appreciably in size and retains moderate magnetic
complexity. Three new regions were numbered today: 9890 (S15W49),
9891 (S08W08), and 9892 (N05E63), all appearing small and relatively
simple in structure.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. Region 9887 appears to be a likely source for
continued C-class and potential M-class flare activity. Region 9885
(N13W14) also retains sufficient size and complexity for potentially
significant flare activity.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
The geomagnetic field was quiet to active. High speed stream effects
from a favorably positioned coronal hole continued, but showed signs
of a gradual waning trend throughout the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mainly quiet to unsettled for the next three days.
Isolated active periods are possible in local nighttime sectors
during the next 12-24 hours as high speed stream effects continue to
wane. A chance for moderate to high flux levels of greater than 2
MeV electrons at geosynchronous orbit exists for the next three days.
