International Dark Sky Week

From April 4 through April 10, 2010, International Dark Sky Week celebrates the heritage of the nighttime sky by encouraging people to turn of unnecessary lights. The event began in 2003 as National Dark-Sky Week in the United States and officially became international in 2009, the International Year of Astronomy. The key to success is the broadest possible participation.

Here are some suggestions on how to participate in International Dark Sky Week:

• Turn out your outdoor lights during the week whenever it is safe to do so.
• Light only when and where needed.
• Encourage friends and neighbors to do the same.
• Change lights to a more energy-efficient type and install shielded fixtures where possible.
• Look for nearby star parties or events at a local observatory during the week where you can promote dark skies awareness.
