IOTA/IOTA-ES occultation update for (805) Hormuthia / TYC 0191-00967-1 event on 2023 Feb 11, 12:14 UT Visible from New Zealand, Australia Summary ------- On 2023 Feb 11 UT, the 71.8 km diameter asteroid (805) Hormuthia will occult a 12.1 mag star in the constellation Canis Minor for observers along a path across New Zealand, Australia. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.60 mag to 15.62 mag (the magnitude of the asteroid) for at most 4.830 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.
