I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 03.03.2026 at 23:00 UTC was 144 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 March 01-03.
An equatorial coronal hole (CH1348) will likely rotate into an Earth facing position on March 04.
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 440 Km/s on March 03 at 21:20 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 -10 nT on March 03 at 20:45 UT during the last 24 hours.
The geomagnetic field was at quiet to minor storm (G1) 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 active levels on March 04-05 and at quiet to unsettled levels on March 06.
