Details:
As the Kp was quite high I used my town light cancellation method. Two photos from same position 40 minutes apart.Took the difference and increased brightness.
Only lights which have changed show i.e. clouds, planes, house lights, star positions and hopefully aurora.
Can someone please try this to confirm method is valid.
Each exposure 20s, f2, iso 800.
