A beautiful display of colors lit up the sky on Tuesday night as the Aurora Borealis dipped as far south as Michigan and Wisconsin, and intense displays of northern lights were seen at higher latitudes.

This week’s heightened aurora activity is being caused by the arrival of a coronal mass ejection from August 22, with some interesting enhancements. Space.com explains:

As NOAA analysts predicted, the solar wind speed did not change much in response to the CME. However, the storm cloud contained a south-pointing magnetic field that opened a crack in Earth’s magnetosphere. Solar wind is pouring in to fuel the ongoing display.

The resulting aurora photos were fantastic, as seen on Flickr and social media:

The aurora was also cranking in the southern hemisphere:
