Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 75 Issued at 2200Z on 17 Mar 2018
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (18 Mar, 19 Mar, 20 Mar).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at unsettled to active levels for the past 24 hours.
Solar wind speed reached a peak of 537 km/s at 15/2208Z. Total IMF
reached 13 nT at 16/1755Z. The maximum southward component of Bz reached
-9 nT at 16/1606Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 13732 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (17 Mar, 18 Mar) and
quiet to unsettled levels on day three (19 Mar).
