Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 77 Issued at 2200Z on 18 Mar 2018
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 to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 575 km/s at 18/2027Z. Total IMF
reached 10 nT at 18/2001Z. The maximum southward component of Bz reached
-9 nT at 18/1953Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 7111 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (19 Mar), quiet to unsettled
levels on day two (20 Mar) and unsettled to active levels on day three
(21 Mar).
