IOTA/IOTA-ES occultation update for (202) Chryseis / UCAC4 390-074561 event on 2023 Jun 05, 22:34 UT Visible from India, SW Asia, Africa Summary ------- On 2023 Jun 05 UT, the 88.3 km diameter asteroid (202) Chryseis will occult a 10.9 mag star in the constellation Serpens for observers along a path across India, SW Asia, Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.61 mag to 12.22 mag (the magnitude of the asteroid) for at most 6.700 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.
