Timelapse: Aurora and noctilucent clouds together

I found a great time-lapse video I’d like to share with you. It shows both aurora and noctilucent clouds at the same time, something I’m not sure that was shot before. The photographer who captured it isĀ Maciej Winiarczyk from the Caithness Astronomy Group.

I guess all of you are familiar with aurora and how it is created, but noctilucent clouds are still somewhat unknown phenomena. These are the clouds in a very high part of Earth’s atmosphere at altitudes of around 76 to 85 kilometers (47-53 miles). They are normally too faint to be seen but become visible when illuminated by sunlight below horizon. You can read more about them on Wikipedia.

Anyway, here’s the video, enjoy:
