Milky Way over sunflowers

It's a panorama image of 7 individual photoes taken at a sunflower field near Veszprem, Hungary. There's some orange coloured light pollution of Veszprem visible on the small clouds at the left side but between and above these clouds the very faint purple colouration is an aurora. (The aurora was also seen in the Czech Republic on the night of 15/16th July, and of course at many other places being closer to the magnetic north pole). I could not see the aurora but when checking my pics I noticed it on many of them taken in about 30 minutes. Later it disappeared. Crops were lit by a small pocket flashlight.
A cold front sweeped my sky clear so the seeing was very good that's why the Milky Way was so bright despite being only at 3 kms distance of my hometown.
Here's a bigger size version of the panorama pic:
