Earth Hour Chania Crete Greece 28-3-2009


This is a small documentary of Earth Hour in Chania, Crete Greece. The Crete Astronomy Friends Club recorded the event using a Sony videocamera using two modes. The first using the CMOS of the video camera and the second using the infrared receiver which gave much better detail of the city lights. We also measured light pollution using an Unihedron, Sky Quality Meter (SQM-L) which recorded a difference of 1 mag (from 18.82 to 20.01 Mag/arcsec2. The Electricity company reported a drop of 10% in consumption for the hour between 20:30 to 21:30 for the city of Chania and an average of 3% drop in consumption for the island of Crete. There is a small introduction of the project in Greek followed by video recordings and photographs.
