This image may not be used to state or imply the endorsement by NRAO, AUI or NSF of any company or product False colour radio image of the Sun at a wavelength of 20 cm, taken by the Very Large Array (VLA) radio telescope, New Mexico, on September 26, 1980. The bright regions, which form 2 bands along the solar equator, are hot, dense gas in the solar corona. These occur above sunspots where the hot hydrogen and helium are confined & held above the Sun's surface by strong magnetic fields. The brightest areas, where the gas is densest, are white. The dark blue areas are regions of very low brightness. These are regions, known as coronal holes, where the solar corona is of extremely low density. Observers: G. Dulk & D. Gary. VLA in D-configuration using 27 antennae. Resol- ution 40 arcsec, field of view This picture may not be used to state or imply the endorsement by NRAO, AUI or NSF of any company or product.
