IOTA/IOTA-ES occultation update for (1191) Alfaterna / TYC 0177-00951-1 event on 2023 Nov 05, 18:38 UT Visible from Japan, China, Russia Summary ------- On 2023 Nov 05 UT, the 45.1 km diameter asteroid (1191) Alfaterna will occult a 10.9 mag star in the constellation Canis Minor for observers along a path across Japan, China, Russia. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.54 mag to 10.39 mag (the combined magnitude of the asteroid and the close companion star) for at most 8.370 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.
