SDF Number 156 Issued at 2200Z on 05 Jun 2019

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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 (06 Jun, 07 Jun, 08 Jun).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 365 km/s at 05/0414Z. Total IMF reached 6 nT at
05/0018Z. The maximum southward component of Bz reached -5 nT at
05/0411Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 178 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (06 Jun) and quiet to unsettled levels
on days two and three (07 Jun, 08 Jun).
