“Radio waves from the solar coro have long wavelengths, and as resolution is proportiol to wavelength, our images ordirily have rather low spatial resolution. But we can capture sharper images as we move in the direction of the Moon’s motion as it blocks different parts of the Sun at different times,” said Dale Gary, professor at the New Jersey Institute of Technology (NJIT). “Radio waves are sensitive to the otherwise invisible coro of the Sun, especially its magnetic field, so we will use the eclipse to make high-resolution images of the coro above active regions.” Using the NJIT’s Expanded Owens Valley Solar Array (EOVSA) and from the Jansky Very Large Array (VLA) radio telescope, the researchers will be able to cover between 75 to 80 per cent of the sunspots at microwave radio wavelengths.
