IOTA/IOTA-ES occultation update for (598) Octavia / TYC 0068-00101-1 event on 2023 Oct 20, 13:32 UT Visible from Australia Summary ------- On 2023 Oct 20 UT, the 76.1 km diameter asteroid (598) Octavia will occult a 10.7 mag star in the constellation Taurus for observers along a path across Australia. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.03 mag to 12.52 mag (the magnitude of the asteroid) for at most 15.780 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.
