RASC Dark-Sky Sites

RASC-Designated Dark-Sky Sites

The RASC has developed formal guidelines and requirements for three types of light-restricted protected areas: Dark-Sky Preserves, Nocturnal Preserves, Urban Star Parks.

 

Dark-Sky Preserve (DSP)

A Dark-Sky Preserve is an area in which no artificial lighting is visible and active measures are in place to educate and promote the reduction of light pollution to the public and nearby municipalities. Sky glow from beyond the borders of the Preserve will be of comparable intensity, or less, to that of natural sky glow.

 

 

Nocturnal Preserve (NP)

The primary focus is to protect the nighttime environment, and astronomical access is not a prerequisite.

 

Urban Star Park (USP)

Sky glow from beyond the borders of the Reserve may be visible to observers within the area, but the skies are still usable for astronomy.

 

Many sites have been designated across Canada - to find the one nearest you, see the list of sites.

The focus of our Dark-Sky Sites Program primarily is to protect the nocturnal environment, with outdoor lighting requirements that are stringent and effective. We officially recognize Canadian parks and other areas that meet these guidelines and successfully apply for one of these designations.

For technical information or for those interested in applying, please refer to these resources. If you have a favourite dark site, please encourage them to start the designation process by sending an email to the RASC National Office or the Light-Pollution Abatement Committee.
