IOTA/IOTA-ES occultation update for 2013 GN158 / UCAC4 383-070094 event on 2023 Apr 16, 05:24 UT Visible from Summary ------- On 2023 Apr 16 UT, the 75.2 km diameter asteroid 2013 GN158 will occult a 14.8 mag star in the constellation Libra 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 24.29 mag (the magnitude of the asteroid) for at most 3.420 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).
