IOTA/IOTA-ES occultation update for (76) Freia / UCAC4-347-094170 event on 2023 Jun 22, 00:49 UT Visible from Africa, South America, Central America Summary ------- On 2023 Jun 22 UT, the 166.8 km diameter asteroid (76) Freia will occult a 12.4 mag star in the constellation Ophiuchus for observers along a path across Africa, South America, Central America. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.56 mag to 13.69 mag (the magnitude of the asteroid) for at most 10.970 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.
