IOTA/IOTA-ES occultation update for (405) Thia / TYC 5517-01194-1 event on 2023 Jun 25, 13:26 UT Visible from China Summary ------- On 2023 Jun 25 UT, the 117.3 km diameter asteroid (405) Thia will occult a 9.5 mag star in the constellation Crater for observers along a path across China. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.20 mag to 12.61 mag (the magnitude of the asteroid) for at most 5.290 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.
