I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 09.01.2026 at 23:00 UTC was 117 sfu.
The background X-Ray flux is at the class B4.2 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on January 07.
An equatorial coronal hole (CH1338) will like become Earth facing on January 06-09.
A CME was observed on January 08 at 17:00 UT. This CME is expected to reach Earth between on January 10 at 23:53 UT and on Jnuary 11 at 09:40 UT according to EAM predictions.
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 561 Km/s on January 09 at 09:10 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 -8 nT on January 10 at 02:50 UT during the last 24 hours.
The geomagnetic field was at quiet to active levels during the last 24 hours.
The Kp index now is at unsettled levels with Kp=3.
IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm (G1) levels on January 10-11 due to the effects of the recurrent coronal hole high speed stream and the CME and at quiet to unsettled levels on January 12.
