IOTA/IOTA-ES occultation update for (203) Pompeja / TYC 6867-00322-1 event on 2023 Jun 08, 05:16 UT Visible from Central America Summary ------- On 2023 Jun 08 UT, the 117.6 km diameter asteroid (203) Pompeja will occult a 11.9 mag star in the constellation Sagittarius for observers along a path across Central America. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.57 mag to 13.13 mag (the magnitude of the asteroid) for at most 12.240 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.
