Instrumented readings from the National Park Service Night Sky Program, providing the most accurate SQM and Bortle classifications.
Dune Trail
Sleeping Bear Dunes NL
"No clouds, but high moisture in atmosphere is creating poor transparency. Stars are soft, with a ring of moisture visible around bright stars. High airglow apparent. Milky Way just visible, no detials apparent. Travese City light dome dominates the eastern horizon. Reflection of Travese City dome is visible on Glen Lake, further impacting dark adaptation in that direction. Transparency improved over the night, with the best conditions at the end of data collection. Bortle Class would be better under better atmospheric conditions."
