Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 302 Issued at 2200Z on 29 Oct 2014
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M1 event observed at
29/1433Z from Region 2192 (S12W84). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a chance for X-class flares on day one (30 Oct) and likely to be
low with a chance for M-class flares and a slight chance for an X-class
flare on day two (31 Oct) and likely to be low with a slight chance for
an M-class flare on day three (01 Nov).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
454 km/s at 28/2128Z. Total IMF reached 6 nT at 28/2143Z. The maximum
southward component of Bz reached -5 nT at 28/2349Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1466 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (30 Oct) and quiet to
unsettled levels on days two and three (31 Oct, 01 Nov). Protons greater
than 10 Mev have a chance of crossing threshold on day one (30 Oct) and
have a slight chance of crossing threshold on day two (31 Oct).
