I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 09.09.2026 at 23:00 UTC was 109 sfu.
The background X-Ray flux is at the class B3.6 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on September 06-08.
A small equatorial coronal hole (CH1397) rotated across the central meridian on September 08.
II. Solar Energetic Particle Events
Protons fluxes are quiet.
The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm level on September 09.
III. Interplanetary and Geomagnetic conditions
The solar wind speed measured by ACE satellite reached the max value 506 Km/s on September 09 at 22:27 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 -6.81 nT on September 09 at 13:43 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 unsettled levels with Kp=3.
IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on September 10-12.
