Go Lights Out 2020
Mark your calendars for the 5th annual Lights Out Portland, an event to kick off fall lights out where residential households and commercial buildings dim their lighting in order to raise awareness about the impact of light pollution on migrating birds, about wasted energy in the form of light thrown up into the sky, and about preserving our ability to see stars from the city.
Building owners, businesses, and residents are encouraged to keep joining us from dusk to dawn each night from September 19 through October 19–the period during which peak numbers of birds will be moving through our airspace.
Visit CSU’s Lights Out Alerts page for Red Alert nights when we really need to take action! We will also post Red Alert nights on our Facebook Page.
