Report of Solar Geophysical Activity (RSGA)


Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 164 Issued at 2200Z on 13 Jun 2013

IA.  Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (14 Jun,
15 Jun, 16 Jun).

IIA.  Geophysical Activity Summary 12/2100Z to 13/2100Z: 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 439 km/s at
13/0331Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 786 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (14 Jun, 15 Jun, 16
Jun).
