IOTA/IOTA-ES occultation update for (505) Cava / TYC 1388-01560-1 event on 2022 Nov 18, 00:01 UT Visible from Africa Summary ------- On 2022 Nov 18 UT, the 108.4 km diameter asteroid (505) Cava will occult a 10.8 mag star in the constellation Cancer for observers along a path across Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.78 mag to 12.34 mag (the magnitude of the asteroid) for at most 15.640 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.
