If you really believe what the travel blogs and travel agencies been telling you, go ahead. But it will not disappear, just that chances of seeing will be lower as you go into the middle and third quarter of the cycle.
At the lowest point, unless you are staying an extended stay - like the entire winter season, in those locations, chances are you will not be able to catch it because it could be, at best, appear only once a month.
Although i have heard from people in the arctic circle that they could still see some faint auroras even during the lowest point - how true it is, I have no idea since I have not spend a winter season there (too cold for me). I only know that to them aurora is like normal experience, which they find it interesting that people like us will travel so far to see it (and in doves lately).
