IOTA/IOTA-ES occultation update for (399) Persephone / UCAC4 497-054736 event on 2023 May 13, 09:07 UT Visible from Australia, New Zealand Summary ------- On 2023 May 13 UT, the 45.9 km diameter asteroid (399) Persephone will occult a 12.0 mag star in the constellation Leo for observers along a path across Australia, New Zealand. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.33 mag to 14.22 mag (the magnitude of the asteroid) for at most 3.890 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.
