Auroras to be Visible Across Whole US
A stronger than expected magnetic storm will make auroras visible across the whole of the northern hemisphere Saturday night. On Friday night, the sky glowed red in the US soutwest and west, and into Mexico. In Norway, the auroras were so bright that they changed night into day. The best time to see auroras is in the deepest part of the night, around midnight. City lights will obliterate subtle displays, but many Americans could enjoy a dramatic display tonight.
