SDF Number 132 Issued at 2200Z on 11 May 2020
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: 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 (12 May, 13 May, 14 May).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 354 km/s at 11/0522Z. Total IMF reached 5
nT at 11/0257Z. The maximum southward component of Bz reached -4 nT at
11/0224Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 177 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (12 May, 13 May, 14
May).
