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 194 publicerat klockan 2200Z på 13 Jul 2011IA. Analys av solfläcksgrupper och solaktivitet från 12-2100Z till 13-2100Z Solar activity was very low during the past 24 hours.
New Regions 1252 (N25E62) and 1253 (N14W12) were numbered today and
are Cso-beta and Bxo-beta type groups respectively. Region 1247
(S18W54) produced a few B-class events early in the period but has
since decayed to an Hsx-alpha group and remained quiet. All other
regions remained quiet and stable.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low with isolated C-class activity likely for the next three days
(14-16 July).
IIA. Sammanfattning av geofysisk aktivitet 12-2100Z till 13-2100Z
The geomagnetic field was quiet to unsettled for the past 24 hours
due to residual effects from a recurrent coronal hole high speed
stream (CH HSS). 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 unsettled to active with a slight chance for isolated
minor storm periods on day one (14 July) due to the anticipated
arrival of the CME observed on 11 July. Quiet to unsettled
conditions are expected on day two (15 July) as effects from the CME
subside. Mostly quiet conditions are expected on day three (16
July).
