IOTA/IOTA-ES occultation update for (250) Bettina / TYC 7348-00894-1 event on 2023 May 05, 02:51 UT Visible from Africa, South America Summary ------- On 2023 May 05 UT, the 99.1 km diameter asteroid (250) Bettina will occult a 10.5 mag star in the constellation Scorpius 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 1.43 mag to 11.60 mag (the combined magnitude of the asteroid and the close companion star) for at most 7.870 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.
