Report of Solar-Geophysical Activity 2023 Jan 06 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 6 Issued at 2200Z on 06 Jan 2023IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z
Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a X1 event observed at
06/0057Z from Region 3182 (S16E59). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (07 Jan, 08 Jan, 09 Jan).
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 546 km/s at 06/0903Z. Total IMF reached 12
nT at 06/0841Z. The maximum southward component of Bz reached -6 nT at
06/1235Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 149 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (07 Jan,
08 Jan, 09 Jan). Protons have a slight chance of crossing threshold on
days one, two, and three (07 Jan, 08 Jan, 09 Jan).
