IOTA/IOTA-ES occultation update for (519) Sylvania / TYC 5269-00817-1 event on 2024 Jun 26, 05:46 UT Visible from Summary ------- On 2024 Jun 26 UT, the 45.0348697885354 km diameter asteroid (519) Sylvania will occult a 9.3 mag star in the constellation Cetus for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 4.25 mag to 13.55 mag (the magnitude of the asteroid) for at most 2.300 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).
