IOTA/IOTA-ES occultation update for (230) Athamantis / UCAC4 505-001720 event on 2022 Dec 21, 17:50 UT Visible from SW Asia, Europe Summary ------- On 2022 Dec 21 UT, the 111.5 km diameter asteroid (230) Athamantis will occult a 12.3 mag star in the constellation Pisces for observers along a path across SW Asia, Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.45 mag to 11.58 mag (the magnitude of the asteroid) for at most 11.860 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.
