Lightcurve results for Asteroid 6327 1991 GP1.
No reasonable period was derived.
Asteroid 6327 1991 GP1 is a main belt asteroid that was discovered on 9 April, 1991 by E. F. Helin at Palomar. The semi-major axis is 2.44 AU and the eccentricity is 0.227 and the inclination is 14.44 degrees.
I observed this asteroid on 1 night during June 2005 when it was in the field of another asteroid I was observing. Although the asteroid showed a good change in brightness, the lightcurve was too incomplete for a reasonable period to be derived.
