IOTA/IOTA-ES occultation update for (95) Arethusa / UCAC4 576-012121 event on 2023 Oct 05, 00:43 UT Visible from Europe, Arabia Summary ------- On 2023 Oct 05 UT, the 143.8 km diameter asteroid (95) Arethusa will occult a 12.3 mag star in the constellation Taurus for observers along a path across Europe, Arabia. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.95 mag to 12.63 mag (the magnitude of the asteroid) for at most 28.290 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.
