Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 29 Issued at 2200Z on 29 Jan 2023

IA.  Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
29/0012Z. There are currently 6 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (30
Jan, 31 Jan, 01 Feb).

IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 544 km/s at 28/2140Z. Total IMF reached 5 nT at
29/0246Z. The maximum southward component of Bz reached -3 nT at
29/1238Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 606 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (30 Jan, 31 Jan, 01
Feb).
