Aurora Dashboard Information

Image of the Aurora

When and where can you see the northern and southern lights also known as the aurora? This page provides a prediction of the aurora’s visibility tonight and tomorrow night in the charts below. The animations further down show what the aurora’s been up to over the last 24 hours and estimates what the next 30 minutes will be like. The aurora’s colorful green, red, and purple light shifts gently and often changes shape like softly blowing curtains.
