39678 Ammannito           Discovered 1996 June 12 by A. Boattini and L. Tesi at San Marcello.
Eleonora Ammannito (b. 1979) recently joined a doctoral program at the University of Padua, working on setting up and calibrating the spear model of VIR-MS, the imaging spectrometer of the Dawn mission. As a student in Rome, she wrote on the calibration of VIRTIS, the imaging spectrometer of the Rosetta mission.
