IOTA/IOTA-ES occultation update for (29665) 1998 WD24 / UCAC4 297-134862 event on 2024 Sep 19, 00:39 UT Visible from Summary ------- On 2024 Sep 19 UT, the 21.2964215174324 km diameter asteroid (29665) 1998 WD24 will occult a 11.8 mag star in the constellation Scorpius for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 6.09 mag to 17.88 mag (the magnitude of the asteroid) for at most 1.150 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.
