IOTA/IOTA-ES occultation update for (345) Tercidina / UCAC4 486-023796 event on 2021 Jan 28, 20:53 UT Visible from Africa Summary ------- On 2021 Jan 28 UT, the 98.5 km diameter asteroid (345) Tercidina will occult a 12.3 mag star in the constellation Monoceros for observers along a path across Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.64 mag to 12.03 mag (the magnitude of the asteroid) for at most 15.9 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.
