Last September, a massive new region of magnetic field erupted on the Sun’s surface next to an existing sunspot. The powerful collision of magnetic fields 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 New Jersey Institute of Technology’s (NJIT) recently expanded Owens Valley Solar Array (EOVSA).

With 13 antennas now working together, EOVSA was able to make images of the flare in multiple radio frequencies simultaneously for the first time...
