Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 77 Issued at 2200Z on 18 Mar 2019
IA. Analysis of Solar Active Regions and Activity from 17/2100Z to
18/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (19 Mar, 20 Mar, 21 Mar).
IIA. Geophysical Activity Summary 17/2100Z to 18/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 408 km/s at 17/2142Z. Total IMF reached 6 nT at
18/0047Z. The maximum southward component of Bz reached -3 nT at
18/0111Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 685 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and three (19 Mar, 21 Mar) and quiet
to unsettled levels on day two (20 Mar).
