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 167 Välja antud 2200Z kuni 16 Jun 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 15-2100Z kuni 16-2100Z Solar activity was moderate. Region 775 (N10W86)
produced an M4.0 flare at 16/2022 UTC with associated Type II (989
km/s) and Type IV radio sweeps. A 170 sfu Tenflare and a CME were
also associated with this event. Region 775 also produced a long
duration C1.7 flare at 16/0905 UTC. Region 779 (S17W05) continues
to show growth, but is developing more slowly.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low.
There is a slight chance for another M-class flare from Region 775
as it rotates around the west limb.
IIA. Summaarne geofüüsikaline aktiivsus 15-2100Z kuni 16-2100Z
The geomagnetic field ranged from quiet to major storm levels.
Transient material associated with the CME activity on 14 June
impacted the ACE spacecraft at approximately 16/0830 UTC. A
short-lived period of southward IMF Bz to near -16 nT resulted in a
major storm from 0900 to 1200 UTC. A greater than 10 and greater
than 100 MeV proton enhancement began following today's M4 flare. At
the time of issue, the protons were slowly rising, but had not yet
reached event thresholds. The greater than 2 MeV electrons at
geosynchronous orbit reached high levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be active with isolated minor storming on 17 June due to
the CME activity on 14 June. Conditions should decrease to
predominantly unsettled on 18 June, with quiet to unsettled
conditions expected on 19 June. The greater than 10 and greater than
100 MeV protons are expected to exceed event thresholds early in the
period.
