YES!

While you hunt for aurora borealis even five minutes are history Northern lights can change every single second, they can flow slowly over the sky for few hours or change rapidly in seconds. Biggest, strongest waves usually take just few minutes, but when there is really big solar activity it can last longer. Remember that its all a matter of luck!

TIPS:
- check forecast/solar activity just before you go.
- always check weather forecast for your location. i recommend yr.no
- dress warm, be prepared to stay in one place for long time.

Good luck with you hunting, wish you many succesfull nights with aurora, one of the most fanstastic phenomens on earth.
