Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 57 Issued at 2200Z on 26 Feb 2020
IA. Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27 Feb, 28 Feb, 29 Feb).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 369 km/s at 26/0427Z. Total IMF reached 7 nT at
26/1026Z. The maximum southward component of Bz reached -4 nT at
26/1808Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 1141 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (27 Feb, 28 Feb, 29
Feb).
