Lightcurve results for 5064 Tanchozuru.
Derived period 4.44 +/- 0.01 hours. Amplitude 0.33 +/- 0.05 magnitude.
Asteroid 5064 Tanchozuru is a main belt asteroid with an estimated diameter of about 15 km. It was discovered on March 16, 1990 by Masanori Matsuyama and Watanabe at Kushiro. The semi-major axis is 2.25 AU, the eccentricity is 0.184 and the inclination is 6.56 degrees.
Four nights of observations showed This asteroid was observed on four nights during June 2004. Analysis of the data indicated that the asteroid has a very asymmetric lightcurve, with the second peak being only about half the amplitude of the first peak. The derived period was 4.44 hours. However the result is very uncertain and more work is required on this asteroid.
