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 Jul 13 2200 UTC
Preparati dal SWPC della NOAA© ed elaborati da SpaceWeatherLive.comRapporto Congiunto USAF/NOAA dell'Attività Solare e Geofisica
SDF Numero 194 Emesso alle 2200Z il Jul 13 2003
IA. Analisi delle Regioni Solari Attive e Attività dalle 2100Z-12 alle 2100Z-13
Solar activity was low. Today's activity consisted of a
few, low-level C-class subflares. Newly assigned Region 409 (N16E66)
rotated more fully into view today and was one of the most active
regions. This group is currently the largest on the disk and was the
source of recent flare activity observed on and near the northeast
limb during the last couple of days. Region 401 (S10W31) showed some
development of new spots in the central part of the group but was
stable and quiet. Two additional regions were assigned today: Region
408 (N13E23), a small newly emerged group, and Region 410 (S13E63),
also a small group that has just rotated into view. A thirteen
degree filament located near N26W08 disappeared between 0100-0900
UTC. Post-eruption arcades were visible in SXI and EIT-195 images.
IB. Previsione dell'Attività Solare
Solar activity is expected to be
mostly low, but there is a chance for an isolated M-class event over
the next three days, with Regions 409 and 401 the most likely
sources.
IIA. Sommario dell'Attività Geofisica dalle 2100Z-12 alle 2100Z-13
The geomagnetic field was unsettled to active during the past 24
hours. Solar wind speeds remain somewhat elevated today (around
500-600 km/s), but are lower than yesterday and show an overall
declining trend. The greater than 2 MeV electron fluxes were at high
levels today.
IIB. Previsione dell'Attività Geofisica
The geomagnetic field is
expected to be mostly active over the next three days. Some
persistence of today's activity is expected to linger into tomorrow.
It is possible that transient flow may arrive sometime during the
next three days from the M3 flare of 10 July or from any of the
recent filament eruptions. However, ACE EPAM data do not indicate
the presence of a strong interplanetary shock at this time, making
transient drivers seem less probable than previously. The onset of
effects from another high speed wind stream are expected on day two
or day three as a new coronal hole will be rotating into favorable
position.
