Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 223 Issued at 2200Z on 11 Aug 2014
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: 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
10/2134Z from Region 2137 (S19W23). 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 days one, two, and three (12 Aug,
13 Aug, 14 Aug).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: 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 463 km/s at
10/2320Z. Total IMF reached 11 nT at 10/2103Z. The maximum southward
component of Bz reached -5 nT at 11/1414Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 565 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and three (12 Aug, 14 Aug) and quiet
to unsettled levels on day two (13 Aug).
