The northern part of the country could see pink and red streaks in the skies this week, just in time for New Year's Eve, according to NOAA.
If you go outside after dark to clear skies and are unable to see the color of the aurora, take out your cell phone, brace your arms against your body (to keep the phone motionless), point your lens towards the sky and take a photo. Cell phones often capture more color than humans are able to see with the unaided eye.
