IOTA/IOTA-ES occultation update for (5274) Degewij / TYC 6391-01290-1 event on 2024 Jul 20, 06:27 UT Visible from Summary ------- On 2024 Jul 20 UT, the 16.4071683744475 km diameter asteroid (5274) Degewij will occult a 9.7 mag star in the constellation Aquarius for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 7.37 mag to 17.06 mag (the magnitude of the asteroid) for at most 2.170 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).
