Abstract:
    The Flagstaff Astrometric Scanning Transit Telescope was used to scan
    the sky in search of occultation candidates through which the Centaur
    10199 Chariklo (formerly 1997 CU_26_) will pass in 1999-2005.
    Positions for 96,397 stars (magnitudes 7.5<V<17.3) were determined
    using differential reductions to the ACT catalog of star positions and
    proper motions, and accuracies of +/-30mas were achieved for
    well-exposed images. The ephemeris for 10199 Chariklo was improved by
    including the new positions presented in this paper and, second, by
    correcting older positions taken from the literature for systematic
    errors. During this time period, 10199 Chariklo passes within 2" of
    117 of these stars, which are identified as occultation candidates in
    this paper. Among these, 28 candidates have magnitudes V<15.0, making
    them the best choices for observing programs using portable
    telescopes. Circumstances for each occultation are given. Because the
    angular radius of 10199 Chariklo is only about 15mas, the astrometry
    provided in this paper is only accurate enough for identifying
    possible occultation events and is not sufficient for predicting
    individual shadow paths across the surface of Earth, although
    representative cases are given. Last-minute astrometry with a
    large-aperture telescope will be needed to refine each prediction.
