Solar physicists and space weather experts expect some powerful storms to be generated by the Sun over the coming days or weeks. They have recently observed a massive sunspot on the surface of the star, which may start producing solar flares at any moment.
Dubbed AR 1476, the sunspot cluster is made up of at least ... |
