Instrument Overview
The Compact Coronagraph 1, or CCOR-1, is designed to image the solar corona (the outer layer of the sun’s atmosphere) to detect and characterize coronal mass ejections, which can disrupt Earth's magnetosphere, leading to geomagnetic storms, auroras, and potential disruptions to technology, including electricity and satellite communications. CCOR-1 will be the primary source for critical information about impending geomagnetic storm conditions, allowing NOAA’s Space Weather Prediction Center (SWPC) to issue warnings one to three days in advance.
The below image provides a schematic view of CCOR1.
