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 226 publicerat klockan 2200Z på 14 Aug 2010IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z Solar activity was low. Region 1099 (N18W58) produced a
C4/Sf flare at 14/1005Z with an associated CME. The STEREO-A
spacecraft observed a full-halo signature first visible on COR2 at
14/1109Z. A Type II radio sweep (estimated velocity 406 km/s) was
also observed with this event.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low, with a chance for C-class flares.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field was at quiet levels. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today. The greater than 10 MeV protons at geosynchronous orbit
exceeded threshold at 14/1230Z with a peak flux of 14 pfu at
14/1245Z. The event ended at 14/1410Z. The source is believed to be
region 1099.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be unsettled to active for the next three days. The
increase in activity is in response to a coronal hole high-speed
stream on days one and two (15 - 16 August). The activity on day
three (17 August) is in response to the CME observed on 14 August.
