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 306 Välja antud 2200Z kuni 01 Nov 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 31-2100Z kuni 01-2100Z Solar activity was very low. Todays activity consisted
of a few B-class events; the largest was a B7 at 1505Z from Region
1598 (S11W77). New Region 1603 (N08W18) emerged on the disk and is a
small, simple bipolar region. All the other regions on the disk were
small and void of activity.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low with a chance for an isolated C-class flare.
IIA. Summaarne geofüüsikaline aktiivsus 31-2100Z kuni 01-2100Z
The geomagnetic field ranged from quiet to active levels during the
past 24 hours, with some isolated storm periods at high latitudes.
Solar wind observations from the ACE spacecraft showed continued
driving from a coronal mass ejection; the interplanetary magnetic
field Bz component turned southward at about 0346Z and attained
sustained maximum levels of about -12 nT for several hours. By the
end of the period Bz had weakened to values around -5 nT. Initial
solar wind velocity peaked at about 370 km/s and had declined to
about 310 km/s by the end of the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be generally unsettled for the first day (02 Nov) as the
current disturbance subsides. Quiet levels are expected to prevail
for the second and third days (03-04 Nov).
