IOTA/IOTA-ES occultation update for (1356) Nyanza / TYC 6854-01485-1 event on 2022 Jul 05, 01:54 UT Visible from Africa, South America Summary ------- On 2022 Jul 05 UT, the 61.3 km diameter asteroid (1356) Nyanza will occult a 10.6 mag star in the constellation Sagittarius for observers along a path across Africa, South America. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.12 mag to 14.70 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.
