Solar activity report
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.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 160 Issued at 2200Z on 09 Jun 2014IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z
Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C9 event observed at
09/1229Z from Region 2085 (S20W16). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (10 Jun, 11 Jun, 12 Jun).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 645 km/s at
08/2205Z. Total IMF reached 5 nT at 09/0213Z. The maximum southward
component of Bz reached -3 nT at 09/0721Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (10 Jun, 11 Jun, 12
Jun). Protons have a slight chance of crossing threshold on days one,
two, and three (10 Jun, 11 Jun, 12 Jun).
