A New Investigation of the Rotation Period and Size of 71 Niobe
Abstract
New lightcurves of 71 Niobe show a synodic rotation period of 35.864 ± 0.001 hours, amplitude 0.15 ± 0.02 magnitudes. Six isolated occultation chords have lengths 13 - 76 kilometers. This makes a size significantly larger than the IRAS value of 87 km, and a rotation period near 72 hours allowed by the photometric data, extremely unlikely.
