Larimer County Department of Natural Resources, city of Fort Collins and other open space programs in Northern Colorado will coordinate a regionwide effort to measure the quality of our night skies at 10-11 p.m. Wednesday, Aug. 23, in designated open space locations.

Volunteers are welcome to help in the effort.

The data collected will help inform night sky education programs and contribute toward efforts to designate some area parks and open spaces as certified dark-sky parks.

Dates for orientation, training and distribution of sky quality meters are to be determined.
