The big blast from the sun on Thursday, known scientifically as a coronal mass ejection, may bring some excitement for skywatchers today and tomorrow. Having stalked the aurora last month in Lapland, I can testify that it's a thrilling, thrilling moment when you spot the beginning of a display.
Just on the off chance that you can't travel to the far north tonight, here are a couple of web resources: AuroraMAX, from the Canadian Space Agency, has a live, 180 degree view of the sky over Yellowknife, Northwest Territories. And I learned something in Lapland – use Spaceweather.com. Here's its aurora gallery for this month.
