Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 59 Issued at 2200Z on 28 Feb 2017
IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (01 Mar,
02 Mar, 03 Mar).
IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 453 km/s at 28/0752Z. Total IMF reached 8
nT at 28/0754Z. The maximum southward component of Bz reached -5 nT at
28/0000Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 111 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on days one and two (01 Mar, 02
Mar) and unsettled to active levels on day three (03 Mar).
