IOTA/IOTA-ES occultation update for (4821) Bianucci / HIP 51802 event on 2024 Oct 26, 11:46 UT Visible from Summary ------- On 2024 Oct 26 UT, the 15.0000811222162 km diameter asteroid (4821) Bianucci will occult a 5.8 mag star in the constellation Leo for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 12.67 mag to 18.46 mag (the magnitude of the asteroid) for at most 0.450 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.
