Coronal holes are openings in the sun's atmosphere where solar wind escapes into space. Magnetic force fields guide the wind into a well-defined stream blowing a million miles per hour. There's no danger when the stream hits; Earth's planetary magnetic field protects us. All you have to worry about is missing the auroras.
