On July 3, two powerful solar flares of class M were recorded on the Sun. This was reported to TASS by the Institute of Applied Geophysics.
The first M1.2 flare was recorded at 03:12 Baku time and lasted 13 minutes. The second M1.5 flare occurred at 17:13 Baku time, also lasting 13 minutes.
Solar flares are classified by X-ray intensity into A, B, C, M, and X classes. The weakest A0.0 class corresponds to 10 nanowatts per square meter at Earth orbit. Each subsequent class increases intensity tenfold. Flares can be accompanied by coronal mass ejections, which can cause geomagnetic storms when they reach Earth.
