I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 01.02.2026 at 23:00 UTC was 162 sfu.
The background X-Ray flux is at the class M7.2 level.
A number of M-class and X-class solar flares were produced on February 01 and the biggest was the X8.1.
An X8.1-class solar flare erupted on February 01 at 23:57 UT peak time producing a radio blackout of category R3.
No obviously Earth directed CMEs were observed in available LASCO imagery on January 30-31.
An equatorial coronal hole (CH1342) could rotate across the central meridian on February  03-04.

II. Solar Energetic Particle Events
Protons fluxes are quiet.
The greater than 2 MeV electron flux at geosynchronous orbit mainted at minor storm level on February 01.

III. Interplanetary and Geomagnetic conditions
The solar wind speed measured by ACE satellite reached the max value 351 Km/s on February 01 at 11:00 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 -5 nT on February 01 at 23:25 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 02-04.
