IOTA/IOTA-ES occultation update for (805) Hormuthia / UCAC4 493-045651 event on 2023 Mar 03, 07:50 UT Visible from Canada, USA, Mexico Summary ------- On 2023 Mar 03 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 Canada, USA, Mexico. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.88 mag to 15.92 mag (the magnitude of the asteroid) for at most 7.150 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.
