Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, and navigation signals, and pose risks to spacecraft and astronauts. This flare is classified as an X1.2 flare. An X-class solar flare is the most powerful type of solar flare, and it is classified based on the peak flux of X-rays emitted by the flare. X-class flares are further divided into subclasses, with X1 being the weakest and X9 being the strongest.
An X1.2 solar flare is a solar flare that falls into the X1 class, but is slightly stronger than an average X1 flare. Specifically, an X1.2 solar flare has a peak flux of 1.2 x 10. This is still a very powerful event, and it can cause significant disruptions to radio communications andsignals on Earth. It can also produce a significant amount of solar energetic particles , which can pose a hazard to spacecraft and astronauts in space.
