IOTA/IOTA-ES occultation update for (8181) Rossini / TYC 1766-00423-1 event on 2024 Oct 11, 19:06 UT Visible from Summary ------- On 2024 Oct 11 UT, the 10.93 km diameter asteroid (8181) Rossini will occult a 11.5 mag star in the constellation Aries for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 5.13 mag to 16.63 mag (the magnitude of the asteroid) for at most 1.370 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).
