IOTA/IOTA-ES occultation update for (568) Cheruskia / TYC 2311-02182-1 event on 2023 Oct 11, 04:41 UT Visible from Europe, Central America Summary ------- On 2023 Oct 11 UT, the 80.5 km diameter asteroid (568) Cheruskia will occult a 12.0 mag star in the constellation Triangulum for observers along a path across Europe, Central America. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.43 mag to 13.07 mag (the magnitude of the asteroid) for at most 9.030 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.
