There's another reason to go outside, next to the State Fair, this weekend: The Northern Lights will be visible throughout Minnesota, including the Twin Cities.
According to the Space Weather Prediction Center of the National Oceanic and Atmospheric Administration, moderate geomagnetic storm conditions over the weekend are expected to bring the Aurora borealis to several northern US states.
The best time to watch the spectacle is on Sunday evenings, when the lights are likely to reach as far as South Minnesota ̵
1; the farther you go north, the better the view is a darker area near you. You can also monitor the chances of seeing the Aurora on the website of the Space Weather Prediction Center. In case you do not notice the sight this weekend, the Alaskan Geophysical Institute will broadcast a livestream of the night sky.
