I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 06.02.2025 at 23:00 UTC was 188 sfu.
The background X-Ray flux is at the class C1.7 level.
Two M-class solar flares were produced on February 06 and the largest was the M7.6.
AR3981 erupted on February 06 at 11:04 UT peak time producing a M7.6-class solar flare and a radio blackout of category R2.
No obviously Earth directed CMEs were observed in available LASCO imagery on February 03-05.
An equatorial coronal hole (CH1269) will rotate across the central meridian on February 06-07.

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 522 Km/s on February 06 at 14:35 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 -6 nT on February 06 at 11:55 UT during the last 24 hours.
The geomagnetic field was at quiet to unsettled 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 to unsettled levels on February 07-08 and at quiet levels on February 09.
