Named in memory of Monica De Magistris (1977-1998), a student of physics at Perugia University and a great lover of astronomy who sometimes visited the Santa Lucia observatory. She organized an astronomy exposition as part of Italy's "Scientific and Technological Culture Week" in 1995, giving lectures on the subject to visitors. In her struggle with illness, she was an example of strength, intelligence and passion throughout her short life.
