Earth Hour, 19 March 2016, 8.30 p.m. Local Time


On 19 March 2016, 8.30 p.m. local time, Earth Hour sweeps across the globe, as people turn out their lights for one hour. Pittsburghers are called to turn off non-essential lighting for one hour beginning at 8:30 p.m. Earth Hour has become a worldwide call to “shine a light on climate action.” From astronomy there is shared interest in reduction of light pollution which also saves evergy. There is also interest to see if there is a noticeable difference in the sky during Earth Hour.

Amateur Astronomers Association of Pittsburgh is a strong supporter of dark sky conservation and encourages light pollution education. Light pollution not only takes away the stars and interfers with vision and sleep, it is also an economic drain.  Please look ahead to International Dark Sky Week, April 4-10, 2016.  For more information visit
