Aurora Alert for September 26 and 27!


Skywatchers in northern Europe are already seeing some aurora activity as a strong-to-severe geomagnetic storm is in progress, according to the NOAA Space Weather Prediction Center and The fuel for this storm was a coronal mass ejection over the weekend that has now reached Earth. This is great news for skywatchers, as both the Northern and Southern lights should be spectacular. But this is not so good news for satellite companies. The Goddard Space Weather Lab reports a “strong compression of Earth’s magnetosphere. Simulations indicate that solar wind plasma [has penetrated] close to geosynchronous orbit starting at 13:00 UT.” Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields.

The active region on the Sun will be pointed straight at Earth in few days as the Sun rotates, so this could be a week of high auroral activity. If you are able to capture images, send the to Universe Today via email or upload them to our Flickr page, and we’ll share them!

  1. Awesome! It’s like a Death Star’s superlaser pointing at us! Will it shoot? Place your bets. 😉

      1. That was nothing yet buddy as it was not pointing at us directly. As for now… if it shoots it’s going to get really colorful, not only at far north/south. NOAA bets 40% for X-flare in next 24h! Raise?

  2. Just an aside: Since UT has also readers from other parts of the world, would it be possible to show a map with the predictions for the rest of the world?

    Thank you!
