IOTA/IOTA-ES occultation update for (7896) Svejk / TYC 6863-00024-1 event on 2024 Jun 05, 04:33 UT Visible from Summary ------- On 2024 Jun 05 UT, the 15.2730792432067 km diameter asteroid (7896) Svejk will occult a 8.5 mag star in the constellation Sagittarius for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 8.78 mag to 17.30 mag (the magnitude of the asteroid) for at most 1.630 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).
