Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 291 Issued at 2200Z on 18 Oct 2015
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
17/2335Z from Region 2437 (S19E74). 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 (19 Oct, 20 Oct, 21 Oct).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 490 km/s at 18/1804Z. Total IMF reached 12 nT at 18/0656Z. The
maximum southward component of Bz reached -11 nT at 18/0758Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 770
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (19 Oct, 21 Oct)
and quiet to unsettled levels on day two (20 Oct).
