Sweden in November

Heya! My friend and I are planning a 10 day trip to Sweden this November, with a focus on seeing the northern lights and skating on outdoor rinks and/or frozen lakes. We'll be visiting Stockholm, Gothenburg, and Abisko, and we're aiming for the 2nd and 3rd weeks of November.

Is that a good time to visit for these activities? What are some must-see landmarks or hidden gems that we shouldn’t miss?

Also, if you have recommendations for specific rinks, frozen lakes, or groups we can join for chasing the northern lights, that would be really appreciated!
