IOTA/IOTA-ES occultation update for (523700) 2014 GM54 / UCAC4 542-116473 event on 2023 Jul 30, 12:26 UT Visible from Summary ------- On 2023 Jul 30 UT, the 125.8 km diameter asteroid (523700) 2014 GM54 will occult a 12.6 mag star in the constellation Sagitta for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 9.21 mag to 21.77 mag (the magnitude of the asteroid) for at most 4.990 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.
