Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico, gave a light curve with a short rotation period of 3.8548 ± 0.0001 hours and a brightness variation of 0.43 ± 0.04 in magnitude.[3]References1. ^1 2 {{Citation | last1 = Pilcher | first1 = Frederick | title = Period Determinations for 26 Proserpina, 34 Circe 74 Galatea, 143 Adria, 272 Antonia, 419 Aurelia, and 557 Violetta | work = The Minor Planet Bulletin | volume = 35 | issue = 3 | pages = 135–138 |date=September 2008 | bibcode = 2008MPBu...35..135P | postscript= .}} [1]}} External links
