I. Solar activity--Current StatusSolar Flux (10.7cm) measured on 04.07.2025 at 23:00 UTC was 119 sfu.
The background X-Ray flux is at the class B5.7 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on July 01-03.
A coronal hole (CH1304) at southern hemisphere rotated into an Earth facing position on June 29 - July 04.
II. Solar Energetic Particle EventsProtons and electrons fluxes are quiet.
III. Interplanetary and Geomagnetic conditionsThe solar wind speed measured by ACE satellite reached the max value 440 Km/s on July 05 at 03:10 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 -9 nT on July 04 at 21:15 UT during the last 24 hours.
The geomagnetic field was at quiet to active levels during the last 24 hours.
The Kp index now is at unsettled levels with Kp=3.
IV. 3-day Geomagnetic Activity ForecastThe geomagnetic field is expected to be at quiet to unsettled levels on July 05-07.
