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 165 publicerat klockan 2200Z på 14 Jun 2005IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity was low. Region 775 (N09W59) produced
two C-class flares, a C4.2/1f at 0730 UTC and a C7.4/Sf at 1548 UTC.
LASCO imagery showed an asymmetric full halo CME associated with
the C4.2 flare.
IB. Prognos för solaktivitet
Solar activity is expected to be low.
There is a slight chance of an M-class flare from Region 775 or 776
(S06W48).
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field was at quiet to unsettled levels. A minor
transient from the CME seen on 12 June was observed by ACE at 1750
UTC, followed by an increase in solar wind speed from 450 km/s to
550 km/s. However, Bz remained stable at +/- 5 nT. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly unsettled levels. Active conditions
may be expected on 15 June due to the effects of today's shock
passage. Isolated minor to major storming is possible on 16 and 17
June due to a recurrent coronal hole high speed stream and the
effects of today's full halo CME.
