SDF Number 55 Issued at 2200Z on 24 Feb 2020
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: 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 (25 Feb, 26 Feb, 27 Feb).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 453 km/s at 24/0648Z. Total IMF reached 5 nT at
23/2104Z. The maximum southward component of Bz reached -4 nT at
23/2139Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1568 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (25 Feb) and quiet to unsettled levels
on days two and three (26 Feb, 27 Feb).
