I. Solar activity
--Current Status
Solar Flux (10.7cm) measured on 04.08.2025 at 23:00 UTC was 142 sfu.br>The background X-Ray flux is at the class C1.4 level.
One M1.7-class solar flare erupted on August 04 at 05:00 UT producing a radio blackout of category R1.
No obviously Earth directed CMEs were observed in available LASCO imagery on August 02-04.
A coronal hole (CH1310) will likely rotate across the central meridian on August 05-09.
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 552 Km/s on August 04 at 07:35 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 nT on August 05 at 02:05 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 unsettled levels with Kp=3.
IV. 3-day Geomagnetic Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on August 05-08.
