IOTA/IOTA-ES occultation update for (46) Hestia / UCAC4 505-051717 event on 2023 Oct 23, 22:15 UT Visible from China Summary ------- On 2023 Oct 23 UT, the 121.8 km diameter asteroid (46) Hestia will occult a 11.8 mag star in the constellation Leo for observers along a path across China. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.46 mag to 14.18 mag (the magnitude of the asteroid) for at most 4.310 seconds. This update is based on, astrometry for the asteroid kindly provided by the IAU Minor Planet Center. This work has made use of data from the European Space Agency (ESA) mission Gaia (http://www.cosmos.esa.int/gaia), processed by the Gaia Data Processing and Analysis Consortium (DPAC, http://www.cosmos.esa.int/web/gaia/dpac/consortium). Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.
