IOTA/IOTA-ES occultation update for (1911) Schubart / TYC 0826-00944-1 event on 2023 Feb 21, 10:46 UT Visible from Mexico, W USA, Russia Summary ------- On 2023 Feb 21 UT, the 73.7 km diameter asteroid (1911) Schubart will occult a 10.6 mag star in the constellation Leo for observers along a path across Mexico, W USA, Russia. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.38 mag to 14.99 mag (the magnitude of the asteroid) for at most 6.110 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.
