According to forecasts, the meteorological phenomenon will begin to storm the magnetosphere from six o'clock in the evening on November 28. Throughout the following night, November 29, the storm will gain full strength and by six in the morning will reach a peak of six points, which corresponds to the G2 category — a "moderate storm."
The magnetic storm forecast has been revised: their start is expected not tomorrow, as previously assumed, but already this evening. This clarification was made by specialists from the Solar Astronomy Laboratory of IKI RAN and ISZF SO RAN, who initially predicted the storm for November 29–30, but adjusted the data, shifting the event a day earlier.
The event will apparently be accompanied by a mass ejection, which is 100% likely to pass by Earth. Other scenarios are not being considered, as the main energy of the flare is concentrated on the far side beyond the edge of the solar disk. Only radiation from high-lying flare loops visible from behind the solar limb has reached Earth.
The duration of the phenomenon — almost a day — makes it potentially dangerous to health, especially for people with cardiovascular diseases. During storms, doctors advise weather-sensitive people to reduce their consumption of coffee, salt, and heavy food. It is also recommended to avoid strong stress and anxiety.
