SDF Number 282 Issued at 2200Z on 09 Oct 2018
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (10 Oct, 11 Oct, 12 Oct).
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 632 km/s at 09/0943Z. Total IMF reached 5
nT at 09/0040Z. The maximum southward component of Bz reached -5 nT at
09/0541Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 39176 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (10 Oct) and quiet to
unsettled levels on days two and three (11 Oct, 12 Oct).
