IOTA/IOTA-ES occultation update for (890) Waltraut / TYC 5042-00937-1 event on 2024 Apr 27, 21:10 UT Visible from Summary ------- On 2024 Apr 27 UT, the 27.9464080511643 km diameter asteroid (890) Waltraut will occult a 9.5 mag star in the constellation Ophiuchus for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 5.40 mag to 14.89 mag (the magnitude of the asteroid) for at most 3.030 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.
