SDF Number 169 Issued at 2200Z on 17 Jun 2020
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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 (18 Jun, 19 Jun, 20 Jun).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of approximately 340 km/s at 17/0709Z. Total IMF reached
5 nT at 17/0021Z. The maximum southward component of Bz reached -5 nT at
17/1308Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 165 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (18 Jun, 19 Jun, 20
Jun).
