IOTA/IOTA-ES occultation update for (6710) Apostel / TYC 1323-01922-1 event on 2024 Sep 09, 20:23 UT Visible from Summary ------- On 2024 Sep 09 UT, the 11.681 km diameter asteroid (6710) Apostel will occult a 10.8 mag star in the constellation Gemini for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 8.47 mag to 19.28 mag (the magnitude of the asteroid) for at most 0.510 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).
