I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 10.01.2026 at 23:00 UTC was 114 sfu.
The background X-Ray flux is at the class B5.2 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on January 07 and 09.
An equatorial coronal hole (CH1338) was Earth facing on January 06-10.
An equatorial coronal hole (CH1339) rotated across the central meridian on January 10.
A CME was observed on January 08 at 17:00 UT. This CME was 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 614 Km/s on January 10 at 20:05 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 -17 nT on January 10 at 20:25 UT during the last 24 hours.
The geomagnetic field was at unsettled to moderate storm (G2) 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 11 due to the effects of the recurrent coronal hole high speed stream (CH1338) and the CME and at quiet to active levels on January 12-13.
