Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 181 Issued at 2200Z on 30 Jun 2013

IA.  Analysis of Solar Active Regions and Activity from 29/2100Z to
30/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
30/1517Z from Region 1780 (S13W45). There are currently 6 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 (01 Jul,
02 Jul, 03 Jul).

IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z: 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
601 km/s at 30/1649Z. Total IMF reached 11 nT at 29/2204Z. The maximum
southward component of Bz reached -9 nT at 29/2158Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 934 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (01 Jul, 03
Jul) and quiet levels on day two (02 Jul).
