Learn to Measure the Darkness of Sky Island Skies

April 1, 2021, 4:30 pm - 5:30 pm

Join Globe at Night leader Connie Walker to learn how to measure night sky darkness around you by counting the number of stars visible to the unaided eye in easily recognizable constellations! 

By contributing these simple Globe at Night community science data, you can help identify where the best dark corridors are for migrating wildlife. Then, once trained in the Globe at Night method, Sky Island Alliance invites you to help document the night sky quality along the U.S.-Mexico border between April 3-13th so that we can work to protect the border from new wall lighting.

This event will be held at 4:30 p.m. Arizona Time/PDT.
