IOTA/IOTA-ES occultation update for (19639) 1999 RO63 / TYC 5230-01374-1 event on 2024 Aug 02, 12:48 UT Visible from Summary ------- On 2024 Aug 02 UT, the 8.75695506643504 km diameter asteroid (19639) 1999 RO63 will occult a 8.2 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 9.47 mag to 17.67 mag (the magnitude of the asteroid) for at most 1.000 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.
