309 Fraternitas Light Curve

Discovered 1891 April 6 by J. Palisa at Vienna. This is the Latin word for fraternity. The asteroid was named to commemorate the 25th anniversary of the Maturitaetspruefung Fraternity. With H = 10.4, this asteroid is probably 21-52 Km. in diameter.
A total of 235 observations were collected over five different nights, September 2 and 3 and October 16, 18, and 20, 2001. The period of the lightcurve was determined to be 13.2h +/-0.1h and the amplitude 0.13m +/-0.03m. There is a small gap at one minimum so the coverage is not complete.
