Paper Abstract

NOAA's Geostationary Operational Environmental Satellites (GOES) include instruments focused on both terrestrial weather patterns as well as solar activity. These solar X-ray measurements enable the NWS Space Environment Center to perform operational specification and to forecast Space Weather phenomenon. The disk-integrated solar X-ray flux has been recorded for more than three decades by the GOES X-ray Sensor (XRS). GOES-12 Solar X-ray Imager (SXI) has provided real-time images of the Sun and lower corona since 2003. In October 2004, a sounding rocket underflight was undertaken with the Avalanche X-ray Spectrometer (AXS) to provide reference or "solar truth" spectra and these data are being used to provide absolute calibration for the XRS and SXI instruments. We present a report on the progress of this effort, including results of the data reduction and analysis for the XRS, SXI and AXS. This calibration effort will increase our understanding of SXI and XRS instrument response functions and will improve the accuracy of space weather forecasting.
