The auroras won't be super vivid near larger cities in Central Europe, with a lot of light around you. It's just not north enough and not dark enough. Up north, rural Lapland or so, it can get very vivid during a winter.
Cameras tend to add their extra though.
A surprising thing to me was how the aurora can sometimes be still and sometimes move so fast. It is a strange experience. One would expect something that covers such a large part of the visible sky-dome to move slowly, but instead it can swipe around quite quickly ("like a fox's tail").
Alas, in the northern hemisphere, we've been pretty good eradicating nighttime darkness (and a lot else besides ...).
It really does look like a river of starlight across the sky, once you are a few hundred miles away from shore.
