According to information provided by TASS, citing the Institute of Applied Geophysics, strong flares of the second-to-last class of intensity (M) may occur on the Sun on January 26 and 27.
The institute noted that solar activity will generally be low on these days; however, there is still a possibility of M-class flares.
Solar flares are classified according to the level of X-ray radiation into five categories: A, B, C, M, and X. The lowest class, A0.0, corresponds to radiation at a level of 10 nanowatts per square meter in Earth's orbit. As one moves to the next category, the intensity increases tenfold. These flares can be accompanied by solar plasma ejections, which, upon reaching Earth, can cause magnetic storms.
