IOTA/IOTA-ES occultation update for (1000) Piazzia / UCAC4 677-042617 event on 2022 Dec 20, 22:02 UT Visible from Russia, Europe Summary ------- On 2022 Dec 20 UT, the 50.7 km diameter asteroid (1000) Piazzia will occult a 12.0 mag star in the constellation Auriga for observers along a path across Russia, Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.33 mag to 16.35 mag (the magnitude of the asteroid) for at most 2.930 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.
