15391 Steliomancinelli           Discovered 1997 Oct. 3 by A. Vagnozzi at Stroncone.
Stelio Mancinelli Degli Esposti (1931-2017) was a professor of chemistry in Terni. Deeply keen on mathematics, physics and astronomy, he designed and implemented large sundials in various Italian cities. He was well known for giving lectures about the history of astronomy and for training courses for teachers.
