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 105 Välja antud 2200Z kuni 15 Apr 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z Solar activity was high. Region 9415 (S12W87) produced
an X14/2b flare at 15/1350 UTC. This event had an associated Type
II, with a speed of 1000 km/s, and Type IV radio sweeps. It was
also accompanied by a tenflare of 48000 sfu. A 12 degree filament
located at S23W02 disappeared between 14/2054 UTC and 15/1135 UTC.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. Region 9415 is still capable of producing a major
flare before it rotates over the western limb.
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
The geomagnetic field was unsettled to active. The X-class event
described in Part IA produced proton events at greater than 10 and
100 MeV flux at geosynchronous orbit which are still in progress.
The greater than 100 MeV crossed event threshold at 15/1405 UTC, and
so far have reached a peak flux of 146 pfu at 15/1525 UTC. The
greater than 10 MeV crossed event threshold at 15/1410 UTC and has
reached a peak flux of 951 pfu at 15/1920 UTC. A ground level event
was measured on the Thule riometer at 15/1505 UTC, and a polar cap
absorption (PCA) event began at 15/1950 UTC.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to active for April 16 and 17. Active to minor
storm conditions are expected on April 18 as a result of the X14
mentioned in Part IA above. Effects from a high speed coronal
stream may also be expected on April 18. The greater than 10 MeV
proton event is expected to continue for most of the period, and the
greater than 100 MeV proton event is expected to go below threshold
by sometime on April 16.
