Sorry i am late to reply...
Muslims here are a mix. The biggest groups are Pakistanis, Iraqis, Somalis, Turks and people from Balkan, roughly. But also we have lebanese, Syrians, Kurds, North-African, list is endless really.
My home is not so far from Tromso but now i live in the South west in the second biggest city in Norway. When i go home, we pray after Mekkah time or after nearest city, we dont have sunset or anything there hehe.
Nothern lights are visible mainly in the North of the country, above the Artic Circle, but its possible to see it sometimes in the south too. Its nice.
We can smell flowers almost in middle of town most parts of the country :D
