Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 50 Issued at 2200Z on 19 Feb 2018
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: 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 (20 Feb, 21 Feb, 22 Feb).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 669 km/s at 19/0807Z. Total IMF
reached 7 nT at 19/1249Z. The maximum southward component of Bz reached
-5 nT at 19/0330Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 13452 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (20 Feb) and quiet to
unsettled levels on days two and three (21 Feb, 22 Feb).
