The Solar X-ray Imager (SXI) instrument, designed and built by the Lockheed Martin Solar and Astrophysics Laboratory, was launched on May 24, 2006 on the National Oceanic and Atmospheric Administration (NOAA) GOES-13 spacecraft. The SXI is operated by NOAA's Space Environment Center (SEC) in Boulder, CO and its X-ray images of the Sun are used by space weather forecasters to monitor solar activity. The GOES-13 SXI has better resolution than either the Yohkoh SXT or the GOES-12 SXI and its active internal jitter compensation system is performing as expected to provide stable viewing even when the GOES-13 spacecraft is moving. The SXI observes between 6 and 60A with broad-band filter photometry. Full-disk images covering a 42 arcmin x 42 arcmin field of view with 5-arcsec pixels are normally returned each minute. The instrument is capable of viewing solar flares, active regions, and coronal hole boundaries. We present updated computations of the response of the SXI to thermal plasmas assuming Chianti V5.2 and present early results from temperature and differential emission measure analyses of solar active regions.
