IOTA/IOTA-ES occultation update for (670) Ottegebe / UCAC4 498-054864 event on 2023 Feb 24, 01:21 UT Visible from Africa, S USA Summary ------- On 2023 Feb 24 UT, the 35 km diameter asteroid (670) Ottegebe will occult a 11.7 mag star in the constellation Leo for observers along a path across Africa, S USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.48 mag to 14.07 mag (the magnitude of the asteroid) for at most 2.550 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.
