IOTA/IOTA-ES occultation update for (339) Dorothea / UCAC4 489-047699 event on 2024 Dec 16, 01:10 UT Visible from Summary ------- On 2024 Dec 16 UT, the 44.883 km diameter asteroid (339) Dorothea will occult a 11.0 mag star in the constellation Cancer for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 3.74 mag to 14.68 mag (the magnitude of the asteroid) for at most 6.160 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.
