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 161 Issued at 2200Z on 10 Jun 2013IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z
Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
10/1424Z from Region 1765 (N09W50). There are currently 1 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one and two (11 Jun, 12 Jun) and expected to be very low
with a chance for a C-class flares on day three (13 Jun).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
420 km/s at 10/1553Z. Total IMF reached 10 nT at 10/0342Z. The maximum
southward component of Bz reached -8 nT at 10/0310Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1479 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Jun, 12 Jun, 13
Jun).
