IOTA/IOTA-ES occultation update for (1977) Shura / TYC 2424-00475-1 event on 2023 Jan 17, 07:16 UT Visible from USA Summary ------- On 2023 Jan 17 UT, the 17.1 km diameter asteroid (1977) Shura will occult a 11.3 mag star in the constellation Auriga for observers along a path across USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.91 mag to 16.18 mag (the magnitude of the asteroid) for at most 1.450 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.
