How this works
Cloud, transparency and a seeing proxy come from forecast weather. Site darkness comes from the 2020 skyglow model and is not multiplied into the conditions score. The live sky is illustrated, not photographed. Positions track the selected time; marker presence is not guaranteed visibility. Inputs refresh while the page is visible.
