Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 157 Issued at 2200Z on 06 Jun 2018
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
06/1100Z from Region 2712 (N14, L=179). 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 (07 Jun, 08 Jun, 09 Jun).
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 462 km/s at 06/1655Z. Total IMF reached 9
nT at 06/2100Z. The maximum southward component of Bz reached -7 nT at
06/1822Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 19491 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (07 Jun) and quiet levels
on days two and three (08 Jun, 09 Jun).
