IOTA/IOTA-ES occultation update for (125) Liberatrix / UCAC4 539-030677 event on 2023 Oct 17, 19:55 UT Visible from Japan, China Summary ------- On 2023 Oct 17 UT, the 44.6 km diameter asteroid (125) Liberatrix will occult a 10.5 mag star in the constellation Gemini for observers along a path across Japan, China. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.86 mag to 14.35 mag (the magnitude of the asteroid) for at most 5.510 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.
