Earth Hour March 26th 2011
Earth Hour ran from 20:30 to 21:30 EDT saturday night and we participated by turning off all lights and a lot of other electrical equipment around the house. We spent the time outside in the -5 to -10 degree temps observing the stars and imaging the Kingston Light Pollution Dome.
At approx 20:30, 21:00 and 21:30 we imaged the Kingston light dome in our southeast with our Canon Powershot A540 digital camera on a tripod, with 15 and 64 second exposures. The idea was to see if we could identify any lighting changing due to Earth Hour.
Time (EDT) | 15 second | 64 second |
approx 20:30 | ![]() | ![]() |
approx 21:00 | ![]() | ![]() |
approx 21:30 | ![]() | ![]() |
After a careful inspection of the images, we could find no noticeable change in the light dome due to earth hour participation in the cityof Kingston.
