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 in Astronomy.[1]


The Making of star charts

During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, sixth year Astronomy students were tasked with the making of star charts in class.[3]

Badeea Ali owned a star chart in the 1980s.[4]

During the 1994–1995 school year at Hogwarts School of Witchcraft and Wizardry, Professor Sybill Trelawney had fourth year Divination students complete star charts in class, as part of their studies in Astrology.[2]

In the 1995–1996 school year, fifth year O.W.L students at Hogwarts 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]
