SDF Number 244 Issued at 2200Z on 01 Sep 2018
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: 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 (02 Sep, 03 Sep, 04 Sep).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 415 km/s at 01/1149Z. Total IMF reached 5 nT at
31/2200Z. The maximum southward component of Bz reached -3 nT at
01/1330Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 24184 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and three (02 Sep, 04 Sep) and quiet
to unsettled levels on day two (03 Sep).
