I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 02.07.2025 at 23:00 UTC was 130 sfu.
The background X-Ray flux is at the class B9.4 level.
No obviously Earth directed CMEs were observed in available LASCO imagery on June 29-July 01.
A coronal hole (CH1304) at southern hemisphere will rotate into an Earth facing position on June 29 - July 04.
---CME arrival forecast
A CME was observed on June 28 at 21:00 UT. This CME was expected to reach Earth between on July 01 at 21:18 UT and on July 02 at 02:06 UT according to EAM predictions.

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 405 Km/s on July 2 at 07:45 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 July 03 at 05:25 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 unsettled levels with Kp=3.

IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet to minor storm (G1) levels on July 03 due to the effects of the CME on June 28 and the recurrent coronal hole high speed stream, at quiet to active levels on July 04 and at quiet to unsettled levels on July 05.

Date	Ap index forecast	Geomagnetic Activity level	
03.07.2025	20	Quiet to Minor storm (G1)	
04.07.2025	12	Quiet to Active	
05.07.2025	10	Quiet to Unsettled
