SDF Number 158 Issued at 2200Z on 07 Jun 2019

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: 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 (08 Jun, 09 Jun, 10 Jun).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 312 km/s at 07/1118Z. Total IMF reached 6 nT at
07/1308Z. The maximum southward component of Bz reached -5 nT at
07/1600Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 205 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (08 Jun, 09 Jun)
and quiet levels on day three (10 Jun).
