DarkSky Oregon has established a network of continuously recording Sky Quality Meters (SQMs) in Oregon to measure skyglow. Skyglow is literally the glowing sky at night, due to both man-made artificial light and natural light. SQMs measure the brightness of the night sky and provide a measure of both light pollution and natural light at night. 

The project’s primary aim is to quantitatively measure, interpret, and share skyglow measurements in Oregon to better understand the current level of light pollution in comparison to other regions and to document any changes over a five-year period. The skyglow data will help to inform action toward healthier and safer communities with less light pollution. The data will also support local efforts to nominate sites under DarkSky International’s Dark Sky Place Program.

We are adding SQM sites monthly with new volunteers. You can help to install and maintain a new site.  A goal is to install at least one SQM in each county of Oregon. Contact hello@darkskyoregon.org.
