Scientists measure the intensity of the flares in five classes viz., A, B, C, M, and X, with the first three being low-intensity flares classes, M being a moderate intensity class and X-class flares being the most powerful of all.
On Sunday, October 2, the Sun had a busy day sending out an X-class flare followed by two M-class flares and particulate matter alongside, which scientists refer to as coronal mass ejection (CMEs).The bulk of solar activity did not come to a close with the weekend, with astronomers forecasting a 99 percent chance of C-class flares, 70 percent chance of M-class flares, and 30 percent chance of X-class flares following them.
