These observations ultimately will lead to better predictions for space weather because the evolution of the magnetic field in the solar atmosphere drives all solar eruptions. These eruptions can reach Earth's atmosphere and affect operations of Earth-orbiting communication and navigation satellites.The images were made possible by a set of innovations on Hi-C's optics array. The telescope's mirrors were approximately 9 1/2 inches across. New techniques for grinding the optics and polishing the surfaces were developed for the mirrors. Scientists and engineers worked to complete alignment of the mirrors, maintaining optic spacing to within a few ten-thousandths of an inch.
