Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado, in 2007 gave a light curve with a period of 23.852 ± 0.003 hours and a brightness variation of 0.60 ± 0.03 in magnitude.[3]References1. ^1 2 {{Citation | last1 = Warner | first1 = Brian D. | title = Asteroid Lightcurve Analysis at the Palmer Divide Observatory - March-May 2007 | work = The Minor Planet Bulletin | volume = 34 | issue = 4 | pages = 104–107 |date=December 2007 | bibcode = 2007MPBu...34..104W | postscript= .}} [1]}} External links
