IOTA/IOTA-ES occultation update for (570) Kythera / TYC 0265-00842-1 event on 2023 Mar 28, 00:40 UT Visible from South America Summary ------- On 2023 Mar 28 UT, the 97.4 km diameter asteroid (570) Kythera will occult a 11.6 mag star in the constellation Leo for observers along a path across South America. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.84 mag to 14.39 mag (the magnitude of the asteroid) for at most 7.290 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.
