SDF Number 159 Issued at 2200Z on 08 Jun 2015

IA.  Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 7 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (09
Jun, 10 Jun, 11 Jun).

IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic
field has been at unsettled to major storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 712 km/s at 08/1128Z. Total IMF reached 22 nT at 08/0505Z. The
maximum southward component of Bz reached -21 nT at 08/0505Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (09 Jun), quiet to
unsettled levels on day two (10 Jun) and quiet levels on day three (11
Jun).
