Professor Aurora Sinistra serves as Hogwarts School of Witchcraft and Wizardry’s Astronomy teacher, guiding students through the mysteries of celestial observation and magical star charts. Her expertise in astronomical phenomena makes her an essential member of the school’s faculty, though she maintains a relatively low profile compared to some of her more prominent colleagues.
The professor conducts her lessons atop the Astronomy Tower, the castle’s highest point, where students gather at midnight to study the movements of planets, stars, and other celestial bodies through telescopes. Her classes require precise observation skills and detailed note-taking, as astronomical calculations prove crucial for various branches of magic, including potion-making and divination.
During the tumultuous period of Voldemort’s return, Sinistra demonstrated remarkable courage when faced with her greatest fear. Her boggart takes the form of the Dark Lord himself, revealing the psychological impact his reign of terror had on even the more reserved staff members. Despite this fear, she remained at her post throughout the dangerous years, continuing to educate young witches and wizards in her specialised field.
Her wand specifications remain unknown, as does her former Hogwarts house, though her dedication to precise, methodical teaching suggests qualities that could align with several houses. The professor’s non-corporeal Patronus indicates either incomplete mastery of this advanced spell or a deeply private nature that keeps her most personal magical expressions hidden from others.
