IOTA/IOTA-ES occultation update for (624) Hektor / UCAC4 627-040447 event on 2023 Aug 12, 11:43 UT Visible from W USA Summary ------- On 2023 Aug 12 UT, the 249.818124920389 km diameter asteroid (624) Hektor will occult a 9.6 mag star in the constellation Lynx for observers along a path across W USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 5.82 mag to 15.40 mag (the magnitude of the asteroid) for at most 6.530 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.
