IOTA/IOTA-ES occultation update for (11351) Leucus / UCAC4 509-045671 event on 2023 Sep 09, 11:12 UT Visible from Mexico Summary ------- On 2023 Sep 09 UT, the 35.7 km diameter asteroid (11351) Leucus will occult a 13.2 mag star in the constellation Cancer for observers along a path across Mexico. In the case of an occultation, the combined light of the asteroid and the star will drop by 5.60 mag to 18.82 mag (the magnitude of the asteroid) for at most 1.010 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.
