Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 227 Issued at 2200Z on 15 Aug 2015
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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
15/1236Z from Region 2401 (S11E22). There are currently 2 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 (16 Aug,
17 Aug, 18 Aug).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet to severe storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 550 km/s at 15/1433Z. Total IMF reached 27 nT at 15/0815Z. The
maximum southward component of Bz reached -21 nT at 15/1008Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 192
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (16 Aug), quiet to
active levels on day two (17 Aug) and quiet to unsettled levels on day
three (18 Aug).
