Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 150 Issued at 2200Z on 29 May 2020
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (30 May,
31 May, 01 Jun).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 318 km/s at 29/2049Z. Total IMF reached 5 nT at
29/2057Z. The maximum southward component of Bz reached -3 nT at
29/1116Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 167 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (30 May, 31 May)
and quiet levels on day three (01 Jun).
