Lightcurves and period determination for 817 Annika
Abstract
Minor planet 817 Annika was observed from several sites across Australia over a period of 14 days (29 rotations) during Oct. and Nov., 2002. Lightcurves obtained on 9 nights with unfiltered CCDs have yielded a rotational (synodic) period of 10.560 ± 0.004 hrs. The complete lightcurve exhibits two maxima and two minima, with a total amplitude range of 0.29 ± 0.02 magnitudes.
