IOTA/IOTA-ES occultation update for (2507) Bobone / UCAC4 542-014187 event on 2024 Apr 03, 10:00 UT Visible from Summary ------- On 2024 Apr 03 UT, the 14.4942051541657 km diameter asteroid (2507) Bobone will occult a 11.3 mag star in the constellation Taurus for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 6.33 mag to 17.60 mag (the magnitude of the asteroid) for at most 0.540 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). Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.
