Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 155 Issued at 2200Z on 04 Jun 2014

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: 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
04/0136Z from Region 2077 (S05E03). There are currently 5 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 (05 Jun,
06 Jun, 07 Jun).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: 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 395 km/s at
04/0654Z. Total IMF reached 8 nT at 04/0508Z. The maximum southward
component of Bz reached -5 nT at 04/1915Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (05 Jun) and quiet to unsettled levels
on days two and three (06 Jun, 07 Jun).
