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 134 Välja antud 2200Z kuni 14 May 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z Activity decreased to low levels. Region 9455 (S17W24)
remained the most active of the visible regions. It produced
isolated C-class subflares, the largest of which was a C5/Sf at
14/0324 UTC. No significant changes occurred within this region, but
mixed polarities persisted within its intermediate spots. Some
polarity mixing was also observed in the vicinity of the leading
spots of Region 9454 (N12E18), which was relatively inactive during
the period. The remaining spot groups were unremarkable, including
newly numbered Regions 9458 (S11W45), 9459 (N26W09), and 9460
(S24E60).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low to moderate levels with a fair chance for an isolated M-class
flare from Region 9455. There will also be a slight chance for an
isolated M-class flare from Region 9454.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
Geomagnetic field activity was at unsettled to active levels until
approximately 14/0900 UTC, then decreased to quiet to unsettled
levels for the rest of the period. The greater than 2 MeV electron
flux at geosynchronous orbit increased to high levels during the
latter half of the period.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to be at quiet to unsettled levels during most of the
period with a chance for active levels at high latitudes. The
greater than 2 MeV electron flux is expected to reach high levels
during the first half of the period.
