Solar X-ray Imager

(Abbreviated SXI.) An imager designed to observe the sun?s x-ray emissions providing earth detection and location of flares, loops, coronal holes and coronal mass ejections from the sun that are important for forecasting space weather. The SXI instrument captures a full disk solar image every minute. First flown on the GOES-12 satellite, this device will be included on the GOES-R series of satellites.
