last thunderstorm of the year ?

Sunday evening, September 19th, a coldfront came in from the west-northwest. On the front edge of the precipitation area thunderstorms developed. For the time of year they were rather active thunderstorms. Lightning activity was around 15-20 flashes per minute at it's peak. Also there were a few exceptionally bright CG's (cloud to ground lightning) nearby. Even with a setting of f/10 on my photo-camera they caused a completely white-out of the image.....
Because of the heavy rain and because the thunderstorms were a bit unexpected, I couldn't make much images.


















Autumn is a short season in Transylvania, so it is likely that this was the last thunderstorm of the year.
