What is this?
This is a visual history of the Northern Lights (Aurora Borealis) from 00:00 to 06:00 UTC on Jan 20, 2026.
How to read it:
- Each Line: Shows a 5-minute snapshot of the aurora's power.
- The Stack: Time flows downwards. The lines at the top are from the past, and the bottom line is happening right now.
- Height & Color: The taller and brighter the line, the stronger the aurora was at that moment.
Green lines mean it's quiet. Purple or tall waves mean the aurora is active and strong.
