The onset of geomagnetic disturbances has been recorded on Earth, which in the coming hours may develop into a moderate magnetic storm — level G1–G2 on the international scale. According to the space weather laboratories of IKI and ISZF, the main reason was a coronal hole on the Sun.
At the same time, attention to flare activity is growing. A large active region is emerging on the visible side of the Sun — the same group of spots that generated the only X-ray flare in two months at the end of March. Now it is shifting to the center of the solar disk, and this changes the risk assessment: any new plasma ejection from this zone is highly likely to be directed towards Earth. In this scenario, the threat of a radiation storm increases, which could affect satellite communications, navigation systems, and the operation of high-latitude power grids.
For users of technical systems sensitive to space weather, it is recommended to monitor operational reports: short-term disruptions in shortwave radio communications and errors in satellite navigation at high latitudes are the most likely consequences of the current storm. The peak of disturbances is expected within the next 12–18 hours, after which the geomagnetic situation should gradually stabilize, unless new emissions come from the central active region.
