Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 177 publicerat klockan 2200Z på 26 Jun 2005IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity was at low levels. A C1 flare was
observed late in the period from a source area near N15 on the east
solar limb. The flare occurred at 26/2035Z. Several B-class flares
during the period were also attributed to this yet visible region in
H-alpha. Another full halo CME was observed today on SOHO/LASCO
imagery and it appears to be back-sided. The visible disk is
currently spotless. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low to low levels. An active source region that is just beyond
the northeast limb appears to have the capability of producing
isolated C-class flares.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was at quiet to unsettled levels today. Solar
winds speeds have dropped to 500 km/sec and it appears the weak
coronal hole is waning. The greater than 2 MeV electrons at
geosynchronous orbit reached high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels. Isolated active
conditions are possible on 28 June due to the CME activity seen
yesterday that was related to disappearing solar filaments.
