Rapporto attività solare
Ogni brillamento solare menzionato nel rapporto ha un fattore di scala, applicato dal Centro di Predizione Meteorologica Spaziale (SWPC). A causa del fattore di scala del SWPC, i brillamenti solari sono segnalati come ridotti del 42%, rispetto ai dati di qualità scientifica. Il fattore di scala è stato rimosso dai nostri dati archiviati sui brillamenti solari, per riflettere le unità fisiche reali.
Rapporto dell'Attività Geofisica Solare 2003 Jun 20 2200 UTC
Preparati dal SWPC della NOAA© ed elaborati da SpaceWeatherLive.comRapporto Congiunto USAF/NOAA dell'Attività Solare e Geofisica
SDF Numero 171 Emesso alle 2200Z il Jun 20 2003
IA. Analisi delle Regioni Solari Attive e Attività dalle 2100Z-19 alle 2100Z-20
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. Previsione dell'Attività Solare
Solar activity is expected to range
from low to moderate levels. Region 386 remains capable of
producing an isolated major event.
IIA. Sommario dell'Attività Geofisica dalle 2100Z-19 alle 2100Z-20
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. Previsione dell'Attività Geofisica
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.

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. Further details can be found at http://www.sec.noaa.gov/GOES.html.
