Description: This timelapse video, taken at the Teide Observatory on Saturday, 22 June, 2013, captures in a few minutes the activities and movements of around 1500 people during the Open Days. The video was filmed from the top of the GREGOR solar tower (the largest solar telescope in Europe). Images were taken every 35 seconds and cover the time interval from dawn to just after sunset. Since the date was so close to summer solstice (21 June), a total of 16 hours' activity was covered.
