SDF Number 156 Issued at 2200Z on 05 Jun 2018

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 495 km/s at 04/2106Z. Total IMF reached 9 nT at
05/1140Z. The maximum southward component of Bz reached -2 nT at
05/1618Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 21164 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (06 Jun, 07 Jun, 08
Jun).
