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 205 publicerat klockan 2200Z på 24 Jul 2011IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity was very low during the past 24 hours.
New region 1260 (N20E71) was numbered today, and is initially
classified as an Axx type spot group. Region 1254 (S23W67) and
Region 1259 (N25W10) both decreased in area and remained quiet.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low with a slight chance for C-class activity for the next three
days (25-27 July).
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was quiet during the past 24 hours. Solar wind
data observed at the ACE spacecraft indicated a continued decrease
in solar wind velocity to about 400 km/s. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet on day one (25 July). Quiet to unsettled with a
slight chance for isolated active conditions are expected on days
two and three (26-27). The activity is forecast due to the expected
arrival of a coronal hole high speed stream.
