IOTA/IOTA-ES occultation update for (489) Comacina / UCAC4 499-055777 event on 2023 Jun 15, 13:49 UT Visible from China Summary ------- On 2023 Jun 15 UT, the 136.5 km diameter asteroid (489) Comacina will occult a 11.5 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 2.86 mag to 14.26 mag (the magnitude of the asteroid) for at most 6.520 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.
