J/AJ/107/1814       Chiron occultations                             (Bus+, 1994)

Chiron stellar occultation candidates: 1993-1996 BUS S.J., WASSERMAN L.H., ELLIOT J.L. <Astron. J. 107, 1814 (1994)> =1994AJ....107.1814B (SIMBAD/NED Reference)
ADC_Keywords: Occultations Abstract: A photographic search was conducted for stars that may be occulted by the unusual solar system object (2060) Chiron during the period from fall 1993 through summer 1996. 44 candidates were identified to a limiting V magnitude of 16, and for which the minimum appulse separation with Chiron is predicted to be less than 2.5arcsec. The successful observation of a stellar occultation by Chiron would give a direct measure of its diameter (currently estimated to be between 60 and 300km), and would help considerably in constraining Chiron's surface properties and volatile makeup. If at the time of the occultation, Chiron exhibits a significant coma, there is also the potential for measuring the optical-depth profile of the dust in its inner coma. File Summary:
