Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 207 Issued at 2200Z on 26 Jul 2014

IA.  Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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
26/1320Z from Region 2123 (S15E13). 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 (27 Jul,
28 Jul, 29 Jul).

IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z: 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 427 km/s at
26/1350Z. Total IMF reached 8 nT at 26/0640Z. The maximum southward
component of Bz reached -7 nT at 26/0619Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (27 Jul), quiet to active levels on day
two (28 Jul) and quiet to unsettled levels on day three (29 Jul).
