IOTA/IOTA-ES occultation update for (174567) Varda / UCAC4 440-072597 event on 2023 Mar 18, 09:46 UT Visible from Summary ------- On 2023 Mar 18 UT, the 700 km diameter asteroid (174567) Varda will occult a 15.0 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 5.22 mag to 20.21 mag (the magnitude of the asteroid) for at most 58.200 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).
