M-class solar flare erupts on the Sun, shows NASA; blackouts triggered on Earth, solar storm possible
Yesterday, a massive sunspot spanning 200,000 kilometers containing as many as 12 dark cores was reported on the Sun. As per information from the NASA Solar Dynamic Observatory (SDO), there was a high chance that it could explode at any moment, and that is exactly what happened just an hour ago. An M-class solar flare was seen erupting on the sunspot, whose extreme ultraviolet radiation sparked a short-wave radio blackout on the Earth. While NASA has not been able to confirm the presence of any Earth-bound coronal mass ejection (CME), this information should be revealed in a few hours' time.
