A star chart of the entire Northern Sky, centered on the north celestial pole. The northern celestial hemisphere, also called the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator. This arbitrary sphere appears to rotate westward around a polar axis due to Earth's rotation.
The northern lights are expected to be strongest between Friday, Jan. 31, and Saturday, Feb. 1. The best time to view them is from 10:00 p.m. and 2 a.m. local time.
