Visibility IV / V
The last night cloud play started as a modest little area at about 11.30pm north-northeast, but at midnight it became clear that this would suddenly be really awesome. So nothing more than the back of a city bike and touring the center of Helsinki as a night cloud tourist. The night clouds were really bright and of all shapes. And the show just got better as the night progressed - at least until 4am when I took the last picture of the dawn morning despite the clearly visible night clouds. The main direction was north all the time, but at about 3 o'clock the night clouds covered the whole west.
