Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 136 Issued at 2200Z on 16 May 2017
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare on days one, two, and three (17
May, 18 May, 19 May).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 678 km/s at 16/0601Z. Total IMF reached 7
nT at 15/2305Z. The maximum southward component of Bz reached -4 nT at
15/2112Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 112 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at active to major storm levels on days one, two, and three (17
May, 18 May, 19 May).
