Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 73 Issued at 2200Z on 14 Mar 2019
IA. Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: 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 (15 Mar, 16 Mar, 17 Mar).
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 367 km/s at 14/1609Z. Total IMF reached 6
nT at 14/1644Z. The maximum southward component of Bz reached -5 nT at
14/0959Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 376 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (15 Mar) and quiet to
unsettled levels on days two and three (16 Mar, 17 Mar).
