According to forecasts, solar activity may remain high for several more days.
On January 17, a powerful earthquake occurred in active area 3964. solar flare magnitude M7.4. It began at 13:24 UTC and lasted until 13:39 UTC. It was the largest of five medium-class (M) flares that occurred that day.

Astronomers say no coronal mass ejections (CMEs) were recorded during this flare, meaning the powerful solar flares did not directly impact Earth. However, solar activity continues to increase, with four more M-class flares observed between 02:11 UTC and 13:35 UTC on January 17.

Active region 3964 is currently in a "Beta" magnetic configuration, indicating the possibility of further powerful flares. However, as this region moves toward the western edge of the Sun, the likelihood of solar flares directed at Earth is decreasing with each passing day.
The greatest degradation of radio frequency communications is predicted to occur over the southern Atlantic Ocean, parts of Africa, and South America.
Forecast for the coming days: the probability of M-class solar flares is 55%, and X-class - 15%. The level of solar activity is expected to remain at a low to moderate level until January 19.
Regarding the solar wind, the last 24 hours have shown the influence of the high-speed flow from the coronal hole. The solar wind speed gradually decreased from 480 to 450 km/s, and then increased again to 525 km/s at 07:00 UTC on January 18. These enhanced conditions are forecast to persist until January 19.
During this time, the Earth's geomagnetic field has varied from quiescent to active. Active conditions are expected on January 17 and 18, as well as periods of quiescence or weak activity on January 19.
Powerful solar flares can seriously disrupt technological infrastructure and threaten human health. Electromagnetic emissions affect satellites, navigation systems and radio communications, and magnetic storms can damage power grids. In addition, increased radiation is dangerous for astronauts who do not have sufficient protection.
