SDF Number 78 Issued at 2200Z on 18 Mar 2020
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: 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 (19 Mar, 20 Mar, 21 Mar).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 441 km/s at 18/1942Z. Total IMF reached 7
nT at 18/1205Z. The maximum southward component of Bz reached -4 nT at
18/1706Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 148 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (19 Mar) and quiet levels
on days two and three (20 Mar, 21 Mar).
