Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 147 Issued at 2200Z on 27 May 2018
IA. Analysis of Solar Active Regions and Activity from 26/2100Z to
27/2100Z: 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 (28
May, 29 May, 30 May).
IIA. Geophysical Activity Summary 26/2100Z to 27/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 376 km/s at 27/2003Z. Total IMF reached 6 nT at
27/1808Z. The maximum southward component of Bz reached -3 nT at
27/1000Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 320 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (28 May, 29 May)
and quiet levels on day three (30 May).
