What is this?

These live sky charts show the sky overhead each observatory at the time you're viewing the page. If you see the Sun symbol on the chart, it means it's daytime at the observatory. You can match what you see in the sky charts to the live AllSky cameras that take continuous images of the skies over the observatories.
