NOAA's next-generation GOES-R weather satellite will carry several instruments designed to measure extreme ultraviolet (EUV) and X-ray portions of the solar spectrum that are known to have significant impacts on space weather. The Solar UltraViolet Imager (SUVI) will produce high-resolution, high-cadence images of the full solar disk in six narrow spectral bands centered primarily on EUV iron lines. High-dynamic range (HDR) composite images will be generated from multiple exposures, which will in turn be used to produce difference images that identify and track fast dynamic features in the solar corona, thematic maps that associate pixels with known solar features, and automated reports that describe spatial and spectral characteristics of these features. In addition, whole-disk irradiances will be measured by the EUV and X-Ray Irradiance Sensors (EXIS). EXIS is comprised of two primary components: the Extreme UltraViolet Sensor (EUVS), and X-Ray Sensor (XRS). These will provide both novel (e.g., 5nm-resolution EUV spectra from 5-127nm), and legacy (X-ray flux) data products. This presentation summarizes GOES-R's new solar instruments' capabilities, and discusses how they are expected to enhance the space weather products and services currently offered by NOAA's Space Weather Prediction Center (SWPC) and other space weather enterprises.
