IOTA/IOTA-ES occultation update for (25) Phocaea / UCAC4 395-036742 event on 2023 Jan 09, 15:46 UT Visible from China Summary ------- On 2023 Jan 09 UT, the 72.3 km diameter asteroid (25) Phocaea will occult a 12.5 mag star in the constellation Monoceros 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 0.82 mag to 12.63 mag (the magnitude of the asteroid) for at most 4.850 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.
