Storm S4: the most powerful in the 21st century

According to NOAA data, a radiation storm of level S4 is currently observed, the strongest in the twentieth century. Its intensity is believed to have already exceeded the famous 'Halloween' storms of 2003.

The duration of the next peak could last up to one or two days. The population can expect GPS failures, flight delays and issues, as well as unstable radio communication and navigation. In addition, many people may experience fatigue, irritability, and reduced concentration due to the strong magnetic storm.

Despite the fact that this event may create difficulties for aviation and satellite navigation, it also provides an opportunity to observe bright auroras even at mid and southern latitudes, which is considered a 'pleasant bonus' for viewers around the world.

Context

S4-level storms are considered a rare phenomenon. The most famous example is the 'Halloween Storm' of 2003, when powerful solar flares caused disruptions in satellite communications.
