IOTA/IOTA-ES occultation update for (16834) 1997 WU22 / TYC 583-00369-1 event on 2024 Jan 24, 03:23 UT Visible from Summary ------- On 2024 Jan 24 UT, the 2.29314591447377 km diameter asteroid (16834) 1997 WU22 will occult a 9.8 mag star in the constellation Pisces for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 10.19 mag to 20.01 mag (the magnitude of the asteroid) for at most 0.060 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.
