On 12 April 2007 the ability to point the SXI and XRS solar sensors aboard the GOES-12 spacecraft was lost due to the failure of a component in the electronics box that controls the north-south motion of both instruments. Although the SXI and XRS instruments continue to function, the Sun now enters the field of view only for a brief period twice a year at the equinoxes.
Since it appears highly unlikely that the pointing functionality can be ever be recovered, routine GOES-12 SXI and XRS observations have been suspended indefinitely. Some limited imaging may be attempted for engineering purposes during the equinoxes, but there is no plan at present to reactivate SXI and XRS in operational mode.
