Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 88 Issued at 2200Z on 29 Mar 2018
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 expected to be very low
on days one, two, and three (30 Mar, 31 Mar, 01 Apr).
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 451 km/s at 29/1727Z. Total IMF reached 9 nT at
29/1702Z. The maximum southward component of Bz reached -4 nT at
29/1846Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 43686 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (30 Mar), quiet to unsettled
levels on day two (31 Mar) and quiet levels on day three (01 Apr).
