Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 270 Issued at 2200Z on 27 Sep 2014
IA. Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
27/0837Z. There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(28 Sep, 29 Sep, 30 Sep).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: 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
481 km/s at 27/0306Z. Total IMF reached 7 nT at 27/2035Z. The maximum
southward component of Bz reached -6 nT at 27/0022Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1167 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (28 Sep) and quiet to
unsettled levels on days two and three (29 Sep, 30 Sep). Protons have a
slight chance of crossing threshold on days one, two, and three (28 Sep,
29 Sep, 30 Sep).
