Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 178 Issued at 2200Z on 27 Jun 2014

IA.  Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: 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
27/0114Z. There are currently 6 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 on day one (28 Jun) and likely to be
low with a slight chance for an M-class flare on days two and three (29
Jun, 30 Jun).

IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z: 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 379 km/s at
27/2034Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (28 Jun), quiet to unsettled
levels on day two (29 Jun) and quiet levels on day three (30 Jun).
