Abstract:
GOES-12 Solar X-ray Imager (SXI) took its first official image on September 7th, 2001 after successfully concluding the first phase of post-launch testing. This SXI is a culmination of more than twenty years of effort. NOAA wishes to acknowledge and thank the USAF for funding the SXI and NASA Marshall for building this fine instrument as well as its in-kind support. The instrument is a broadband imager operating in the 0.6-6.0 nm bandpass. It has a full width at half maximum (FWHM) of ~10 arcsec sampled with 5 arcsec pixels in a 512x512 array. When operational, it will provide full-disk solar images at a 1-minute cadence around the clock, except for brief periods during orbital eclipse seasons. Available combinations of exposures and filters allow the entire dynamic range of solar x-ray features to be covered: from coronal holes to X-class flares. In addition, using ratio images from different filters allows temperature and emission measure estimates to be made. To meet operational goals, flexible observing strategies are implemented as recurring sequences of images. Sequences can be selected or modified based on solar activity levels. The operational goals are to: - Locate coronal holes for geomagnetic storm forecasts, - Detect and locate flares for forecasts of solar energetic particle (SEP) events related to flares, - Monitor changes in the corona that indicate coronal mass ejections (CMEs), - Detect active regions beyond east limb for F10.7 forecasts, and - Analyze active region complexity for flare forecasts. NOAA/SEC receives the data, which is being shared with the US Air Force, and NASA in real-time. Products available to the research community are described as Level 0 (raw data) and Level 1. The level 1 data consist of single calibrated images which have had defects removed. All levels of data will be archived at the NOAA National Geophysical Data Center (NGDC). The latest images can be found on SEC's Latest SXI Images web page. SXI testing is proceeding and images are being put on the Web in near real time, i.e., within a minute or so of being taken. Some of the testing, of course, produces rather indecipherable images. However, we also anticipate long periods of relatively 'normal' imaging. Currently, only 'browse' images in PNG format are available for downloading. SolarSoft compatible FITS files will be available in near real-time when the instrument has been fully checked out.
