IOTA/IOTA-ES occultation update for (546) Herodias / UCAC4-680-049069 event on 2022 Dec 27, 19:44 UT Visible from China, SW Asia, Europe Summary ------- On 2022 Dec 27 UT, the 65 km diameter asteroid (546) Herodias will occult a 12.5 mag star in the constellation Lynx for observers along a path across China, SW Asia, Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.12 mag to 13.13 mag (the magnitude of the asteroid) for at most 7.100 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.
