I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 09.06.2026 at 23:00 UTC was 130 sfu.
The background X-Ray flux is at the class B8.6 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on June 07-08.
An equatorial coronal hole (CH1373) will rotate to an Earth facing position on June 09-10.
A CME was observed on June 06 at 14:11 UT.The source is an M1.9-class flare.This CME was expected to reach Earth on June 08 between at 01:00 UT and 23:02 UT according to EAM predictions.
II. Solar Energetic Particle Events
Protons fluxes are quiet.
The greater than 2 MeV electron flux at geosynchronous orbit reached minor storm level on April 09.
III. Interplanetary and Geomagnetic conditions
The solar wind speed measured by ACE satellite reached the max value 479 Km/s on June 09 at 20:55 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 -8 nT on June 09 at 18:05 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=2.
IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on June 10 and at quiet to active levels on June 11-12 due to the effect of the recurrent coronal hole high speed stream.
