Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 142 Issued at 2200Z on 22 May 2017
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 4 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 (23
May, 24 May, 25 May).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 619 km/s at 22/1940Z. Total IMF reached 6
nT at 22/0736Z. The maximum southward component of Bz reached -5 nT at
22/1634Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 26098 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (23 May, 24 May)
and quiet levels on day three (25 May).
