SDF Number 168 Issued at 2200Z on 17 Jun 2018
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 1 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 820 km/s at 16/2202Z. Total IMF reached 8 nT at
17/1845Z. The maximum southward component of Bz reached -6 nT at
17/1851Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 816 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (18 Jun, 19 Jun)
and quiet levels on day three (20 Jun).
