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.

SDF number 171 Välja antud 2200Z kuni 20 Jun 2003

IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 19-2100Z kuni 20-2100Z

Solar activity increased to low levels today. Region 386 (S07E17) produced two low levels C-class flares today along with several B-class flares. The northern portion of the penumbral field appears to have undergone some rotation since yesterday while the delta magnetic structure in the southern leading edge of group has changed little during the period and remains intact. Region 387 (N18E36) was quiescent today although spot coverage and magnetic complexity have both shown growth over the period. Region 389 (S12E14) was newly numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to range from low to moderate levels. Region 386 remains capable of producing an isolated major event.
IIA. Summaarne geofüüsikaline aktiivsus 19-2100Z kuni 20-2100Z
The geomagnetic field was at predominantly unsettled levels today as effects from the western most recurrent coronal hole wanes. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is expected to be at predominantly unsettled levels. Active conditions may exist especially at high latitudes beginning late on day two with the return of a recurrent coronal hole high speed stream.

99999 PLAIN K-Indices: On 16 June, it was determined that a scaling problem exists with the Boulder magnetometer instrument. While this problem, and its fix are being investigated the primary instrument for Boulder K-indices has been switched to the Boulder USGS (via Domsat) magnetometer, effective 1500 UTC on 16 June. GOES Protons: To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. GOES 11 (113W) is now the primary satellite for protons. GOES 12 will continue as the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 (135W) will be the secondary satellite for all SEM sensors - magnetometer, X-ray, and energetic particles. Because of the degraded state of the proton data on GOES-10, its designation as the secondary source for proton data is a short-term solution. More permanent solutions have been identified and are being evaluated. Users will be notified when we define and schedule a permanent fix.
