I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 06.01.2026 at 23:00 UTC was 145 sfu.
The background X-Ray flux is at the class B9.8 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on January 03-05.
An equatorial coronal hole (CH1338) will like become Earth facing on January 06-09.

II. Solar Energetic Particle Events
Protons and electrons fluxes are quiet.

III. Interplanetary and Geomagnetic conditions
The solar wind speed measured by ACE satellite reached the max value 394 Km/s on January 06 at 12:15 UT during the last 24 hours.
The solar wind speed from STEREO A was detected 400 Km/s during the last 24 hours.
The vertical component of IMF Bz reached the max value -4 nT on January 06 at 09:15 UT during the last 24 hours.
The geomagnetic field was at quiet levels during the last 24 hours.
The Kp index now is at quiet levels with Kp=1.

IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet levels on January 07-08 and at at quiet to minor storm (G1) levels on January 09 due to the effect of a recurrent coronal hole high speed stream.

Date	Ap index forecast	Geomagnetic Activity level	
07.01.2026	05	Quiet	
08.01.2026	05	Quiet	
09.01.2026	25	Quiet to Minor Storm (G1)
