I regularly record noctilucent cloud [around summer solstice] and brighter stars with a regular [and thus cheap sub £100] digital compact camera and it should serve to record the Northen Lights [=aurora] when set on 'night mode' [= exposure 3s-6s] and high ISO [say 800-1600 ISO setting] and of course on a tripod - an mini pocketable tripod will serve set on a wall etc. To remove shake [from touching the cam] use the 'delayed action' eg self portrait setting.
Aurora are huge and need a wideangle lens setting and this also uses the lens at its fastest to let in more light than when the cam is fully 'zoomed out' for narrow angle shots.
You can test your cam now on the night sky before you holiday
PS: looking at the spec at

the wideangle =35mm equiv @ f/3.5; exp max=16s and ISO 100-1600 so it should do fine - good luck
