Solar X-ray Imager (SXI) are full-disc X-ray instruments observing the Sun aboard GOES satellites. The SXI on GOES 12 was the first of its kind and allows the U.S. NOAA to better monitor and predict space weather.

Operation

radio communications and satellite communications systems.[2][3]

Failure and termination of the GOES 12 instrument

The XSI and XRS sensors on GOES 12 failed due to a problem with the electrical system which controls the north-south motion functionality of the instruments on April 12, 2007. The SXI and XRS currently have the ability to capture and record images. Due to limited field of view of the x-ray instrumentation, the XSI and XRS and been permanently deactivated.[4]
