Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 290 Issued at 2200Z on 17 Oct 2015
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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
17/2042Z. There are currently 5 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be moderate on
days one, two, and three (18 Oct, 19 Oct, 20 Oct).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: 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
380 km/s at 16/2330Z. Total IMF reached 7 nT at 17/1106Z. The maximum
southward component of Bz reached -6 nT at 17/1921Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 10702 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (18 Oct, 19 Oct)
and quiet levels on day three (20 Oct).
