Aurora movement


Recommended Posts

As a newbie here, thanks for the great community.


Yesterday was amazing and I saw it from Scotland. But one thing that struck me was that the show was quite static with far far less movement in the aurora compared with shows I have seen in the Arctic (and with a much lower Kp). Maybe we just missed it!
 

Does anyone know why this is? What is causing the movement if it is not high solar wind speed/density/IMF/Bt/Bz which we got loads of yesterday ?

This is a resource in partnership with NASA that I learned a lot from, I hope it helps. (The name is cute but I assure you legitimate source),  the part about shapes explains some of the different types
