53 Kalypso, a Difficult Asteroid
Abstract
Previous observations of 53 Kalypso have not resolved a rotation period ambiguity between near 9.035 hours and twice that value. New observations very strongly support the 9.035 hour period, with amplitude 0.10 magnitudes and 3 unequal maxima and minima per cycle in the interval 2011 April ñ July.
