IOTA/IOTA-ES occultation update for (3548) Eurybates / UCAC4 608-031607 event on 2023 Feb 02, 01:11 UT Visible from South America Summary ------- On 2023 Feb 02 UT, the 67.2 km diameter asteroid (3548) Eurybates will occult a 12.3 mag star in the constellation Auriga for observers along a path across South America. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.46 mag to 16.78 mag (the magnitude of the asteroid) for at most 6.860 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.
