These pictures are from the IAP web cameras located at the Leibniz-Institute of Atmospheric Physics at 54.12°N, 11.77°E. The left picture is from a Canon Powershot G6 (technical data), while the right one is from an Axis 211 network camera (technical data). Both cameras are looking towards the North-East so that you can see the Baltic Sea and parts of the sea-side resort Kühlungsborn. During the summer, the G6 is running in the NLC mode, i.d. it's taking a picture every 40s during civil twilight when the sun is more than 5 degrees below the horizon to study noctilucent clouds.
The time base is 'Universal time' (UT), i.e. in winter the time is CET - 1h and in summer CEST - 2h.
