A Star chart was a written document. It was used to represent the positions and movements of the stars, pretty much like an ordinary map. Astronomers usually use these for research or study. An O.W.L.-level wizard or witch should be able of fill in a blank star chart based on some hours of sky gazing.[1]


In the 1995–1996 school year, Fifth year O.W.L students at Hogwarts School of Witchcraft and Wizardry had to "fill in a blank star chart" based on a few hours of observing the night sky as part of their O.W.L exam.[1]
