Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 298 Issued at 2200Z on 25 Oct 2014
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a X3 event observed at
24/2141Z from Region 2192 (S12W21), followed by an X1/3b at 25/1708 UTC.
There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (26 Oct, 27
Oct, 28 Oct).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
466 km/s at 24/2210Z. Total IMF reached 6 nT at 25/0516Z. The maximum
southward component of Bz reached -5 nT at 25/1859Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1967 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (26 Oct, 28
Oct) and quiet to active levels on day two (27 Oct). Protons have a
chance of crossing threshold on day one (26 Oct), have a chance of
crossing threshold on day two (27 Oct) and have a chance of crossing
threshold on day three (28 Oct).
