Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 74 Issued at 2200Z on 15 Mar 2019
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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 (16 Mar, 17 Mar, 18 Mar).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 414 km/s at 15/1358Z. Total IMF reached 8
nT at 15/0601Z. The maximum southward component of Bz reached -6 nT at
15/0124Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 276 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (16 Mar, 17 Mar)
and quiet levels on day three (18 Mar).
