SDF Number 245 Issued at 2200Z on 02 Sep 2018
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 Sep, 04 Sep, 05 Sep).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 384 km/s at 02/1358Z. Total IMF reached 5 nT at
02/1457Z. The maximum southward component of Bz reached -4 nT at
02/1621Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 19396 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (03 Sep) and quiet levels
on days two and three (04 Sep, 05 Sep).
