IOTA/IOTA-ES occultation update for (10658) Gretadevries / TYC 5250-00918-1 event on 2024 Dec 15, 22:35 UT Visible from Summary ------- On 2024 Dec 15 UT, the 13.564 km diameter asteroid (10658) Gretadevries will occult a 10.9 mag star in the constellation Aquarius for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 7.92 mag to 18.80 mag (the magnitude of the asteroid) for at most 0.680 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).
