First Annual One Dark Hour Event Set for April 22

One Dark Hour logoThe Fairfax County Park Authority is encouraging participation in the first annual One Dark Hour event. This April 22, 2022, event will be the kickoff to the celebration of International Dark Sky Awareness Week. The Park Authority is committed to raising awareness to the importance of dark skies as our region continues to grow and urbanize. Dark skies are important to wildlife and plant resources that we all depend on for a healthy ecosystem with clean air and water. Following the county’s outdoor lighting standards would make all our homes dark sky friendly. Dark skies do not demand that we get rid of all the lights, only to have light where and when it is needed. 

To participate in One Dark Hour, simply turn off your outdoor lights between 9 and 10 p.m. on Friday, April 22, 2022. We encourage you to tell your neighbors to magnify the effect. As more people participate each year, we hope to see a demonstration of the power of collective action.

While the lights are out, please look up at the sky and see what you might have been missing. It takes up to 15 minutes for our eyes to become adapted to the dark after looking at the glare of a light. So be patient and wait for the stars to appear. You can also consider visiting Observatory Park at Turner Farm for their free Friday viewing and observance of One Dark Hour. If it is raining or completely cloudy, the observation session will be postponed until April 29, 2022.

Observatory Park at Turner Farm is located at 925 Springvale Road in Great Falls, Virginia. For
