Solar Imaging Suite

(Abbreviated SIS.) SIS is comprised of a Solar X-ray Imager (SXI), a solar x-ray sensor (XRS) for detecting flares, and an extreme ultraviolet sensor (EUVS) for monitoring the main energy sources for the thermosphere and ionosphere. SIS will be flown on the GOES-R series of satellites.
