A CME hit Earth’s magnetic field on May 27th with a day of delay.
At first, the seemingly weak impact barely disturbed our planet’s magnetic environment. Then the storms began and managed to spark G3 – Strong geomagnetic storms and bright auroras.

As Earth passed through the CME’s wake, energetic particles poured through a crack in Earth’s magnetosphere, sparking strong G3-class geomagnetic storms and bright auroras. Here some displays recorded around the world:
You can watch more pictures of the amazing auroras produced around the world here.
The aurora show is not over. Earth is still inside the CME’s wake, and G1-class storms are underway on May 28th. High-latitude sky watchers should remain alert for auroras.
