IOTA/IOTA-ES occultation update for (5628) Preussen / UCAC4 526-049833 event on 2024 Oct 15, 01:44 UT Visible from Summary ------- On 2024 Oct 15 UT, the 13.061 km diameter asteroid (5628) Preussen will occult a 11.3 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 7.38 mag to 18.65 mag (the magnitude of the asteroid) for at most 0.460 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.
