The northern lights are relatively common in Southern Finland when activity is increased (once a month to a few times a week depending on the year) but they are almost always visible low in the northern horizon. Seeing them above the head here is rare, maybe a few dozen times a decade so I was quite excited to see them like this.
The thing is that auroras are not a local phenomenon. Aurora arch is 100 to 200 km tall and the bottom part is at the edge of space so with good conditions they’re visible from a 1000 km range from the point they’re above the head. The same arch visible here was seen all the way in [Northern Germany](https://spaceweathergallery.com/indiv_upload.php?upload_id=181584) last night.

My brain refuses to try to work out how fast that’s actually moving when its so far up and so big.
Absolutely mesmerising.
Hello everyone. This video was shot with Laowa 15mm F/2 and Sony A7III using ISO 25600 and a shutter speed of 1/15 in Tampere last night. Geomagnetic activity was increased due to fast solar wind coming from a [coronal hole](https://sdo.gsfc.nasa.gov/assets/img/browse/2022/01/13/20220113_234753_2048_0193.jpg).

Saw them, the best ones I’ve ever seen.
