With a geomagnetic storm incoming after the most powerful solar flare of the current solar cycle, here's how to image the Northern Lights with a phone and manual camera.

Two strong solar flares in the space of 48 hours will bring stunning auroras to northern states and the Midwest over the next few days.

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.
