LIGHTCURVE ANALYSIS OF NEA (331471) 1984 QY1: A TUMBLING ASTEROID.
Analysis of CCD photometric observations of the near-Earth asteroid (331471) 1984 QY1 show that it is likely in non-principal axis rotation (NPAR), or tumbling. A single period analysis found a dominant period of 45.5 ± 0.5 h, but the true periods of rotation and precession could not be determined.
