Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 1 Issued at 2200Z on 01 Jan 2019
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: 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 (02 Jan, 03 Jan, 04 Jan).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 476 km/s at 31/2204Z. Total IMF reached 5
nT at 01/0556Z. The maximum southward component of Bz reached -4 nT at
01/0949Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1700 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (02 Jan, 03 Jan) and quiet to
active levels on day three (04 Jan).
