Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 267 Issued at 2200Z on 24 Sep 2014
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
23/2316Z from Region 2172 (S11E36). There are currently 5 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (25 Sep, 26 Sep,
27 Sep).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at unsettled to active levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 474 km/s at 24/2014Z. Total IMF reached 8 nT at 24/1803Z. The
maximum southward component of Bz reached -7 nT at 24/1827Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 333
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (25 Sep) and quiet to
unsettled levels on days two and three (26 Sep, 27 Sep).
