Aurora chasers are on high alert for possible geomagnetic storm conditions Oct.3 through Oct. 5 with northern lights possible as far south as Illinois and Oregon.

For prime northern lights viewing in the United States, the strongest activity is forecasted to arrive late Friday night to Saturday morning. Clouds may also clear through the night to provide good vantages for the majority of the country, especially in the Midwest and Mid-Atlantic.

Dark sky destinations perfect for seeing the Northern Lights includes an an International Dark Sky Place (U.S./worldwide), a Dark-Sky Preserve (Canada) or a Starlight Reserve (Spain). Or just look at a light pollution map because anywhere with a dark northern horizon will potentially give you a good view.
