IOTA/IOTA-ES occultation update for (182) Elsa / UCAC4 538-007981 event on 2023 Nov 05, 03:53 UT Visible from Europe, S USA, Mexico Summary ------- On 2023 Nov 05 UT, the 42.5 km diameter asteroid (182) Elsa will occult a 12.4 mag star in the constellation Taurus for observers along a path across Europe, S USA, Mexico. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.35 mag to 11.33 mag (the magnitude of the asteroid) for at most 7.750 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.
