IOTA/IOTA-ES occultation update for (806) Gyldenia / UCAC4 621-021229 event on 2022 Nov 29, 23:08 UT Visible from Russia, E Canada Summary ------- On 2022 Nov 29 UT, the 69.6 km diameter asteroid (806) Gyldenia will occult a 12.2 mag star in the constellation Auriga for observers along a path across Russia, E Canada. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.77 mag to 14.87 mag (the magnitude of the asteroid) for at most 5.030 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.
