Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 15 Issued at 2200Z on 15 Jan 2021
IA. Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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 (16 Jan, 17 Jan, 18 Jan).
IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 324 km/s at 14/2109Z. Total IMF reached 5 nT at
14/2121Z. The maximum southward component of Bz reached -4 nT at
15/1814Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 223 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (16 Jan), quiet to active levels on day
two (17 Jan) and unsettled levels on day three (18 Jan).
