IOTA/IOTA-ES occultation update for (524049) 2000 CQ105 / TYC 1430-00917-1 event on 2023 Apr 12, 14:13 UT Visible from Summary ------- On 2023 Apr 12 UT, the 181.9 km diameter asteroid (524049) 2000 CQ105 will occult a 11.0 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 11.74 mag to 22.72 mag (the magnitude of the asteroid) for at most 10.090 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.
