IOTA/IOTA-ES occultation update for (938) Chlosinde / UCAC4 549-010576 event on 2022 Dec 27, 00:12 UT Visible from Europe, SE Canada, USA Summary ------- On 2022 Dec 27 UT, the 29.5 km diameter asteroid (938) Chlosinde will occult a 13.6 mag star in the constellation Taurus for observers along a path across Europe, SE Canada, USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.50 mag to 15.99 mag (the magnitude of the asteroid) for at most 2.750 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.
