A medium-sized coronal hole is observed on the Sun, located almost exactly on the solar equator — in the same plane as the orbits of the planets, including Earth. This position makes it particularly significant for the geomagnetic situation on our planet.
The high-speed solar wind flow emanating from this hole has already begun to reach Earth. According to forecasts, further intensification of the solar wind is expected within the next 24 hours — its speed may reach 600 km/s, which is approximately 50% above normal. This creates conditions for the occurrence of a minimal, first-level magnetic storm.
The peak of geomagnetic disturbances is predicted for tomorrow, Wednesday, July 23, with possible instability persisting through Thursday, July 24. Overall, the duration of geomagnetic activity should not exceed two days. The probability of stronger storms is estimated as low — about 6%.
