***********************************************************************
1. Solar activity
Solar activity was increasing during the past 24 hours.
Solar Flux (10.7 cm) measured on 21.01.2022 at 20:00 UTC was 97 sfu.
The background X-Ray flux is at the class B2.5 level.
The geomagnetic field was at very quiet to unsettled levels on Jan 21.
AR12929 erupted again on Jan 20 at 06:01 peak time producing a strong M5.5 class solar flare and a radioblackout of category R1. The associated CME is expected to miss Earth but a glancing blow is still possible. According to EAM predictions the arrival of a component from this CME is expected on Jan 23 between 09:10 and 16:15.
A new CME possibly associated with a filament eruption observed on Jan 22 09:53. This CME is expecting to produce a glancing blow at Earth on Jan 24 between 01:23 and 05:22 according to EAM predictions.
The Kp index now is at unsettled levels with Kp=3.
2. Solar Wind Geomagnetic Activity
Solar Wind speed from ACE: 415 km/s.
Solar Wind speed from STEREO A: 320 km/s.
Solar Wind speed from STEREO B: --- km/s.
The southward component Bz is: 2 nT south.
3. Solar Energetic Particle Events
GOES Proton Flux for particles with energies above 10 MeV exceed the SWPC 10 MeV warning threshold on Jan 20 at 08:00 due to the M5.5 solar flare. A solar radiation storm of level S1 was also observed.
4. Coronal Holes
Two new coronal holes (CH1055, CH1056) on the northern hemisphere of the visible solar disk will be in Earth facing position on Jan 20 and 21 respectively.
5. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on Jan 22-23 and at almost quiet levels on Jan 24.
