Toward the end of 2017, a massive new region of magnetic field erupted on the Sun’s surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of potent solar flares, causing turbulent space weather conditions at Earth. These were the first flares to be captured, in their moment-by-moment progression, by NJIT’s then recently opened Expanded Owens Valley Solar Array (EOVSA) radio telescope.
