Report of Solar Geophysical Activity

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 184 Issued at 2200Z on 03 Jul 2014

IA.  Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: 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
03/0359Z. There are currently 8 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(04 Jul, 05 Jul, 06 Jul).

IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
392 km/s at 03/0450Z. Total IMF reached 7 nT at 03/0235Z. The maximum
southward component of Bz reached -7 nT at 03/0457Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (04 Jul, 05 Jul) and quiet to
unsettled levels on day three (06 Jul).
