IOTA/IOTA-ES occultation update for (336) Lacadiera / UCAC4 542-004459 event on 2024 Oct 19, 21:36 UT Visible from Summary ------- On 2024 Oct 19 UT, the 69.738 km diameter asteroid (336) Lacadiera will occult a 10.9 mag star in the constellation Aries for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 2.17 mag to 12.94 mag (the magnitude of the asteroid) for at most 6.490 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.
