IOTA/IOTA-ES occultation update for (5) Astraea / UCAC4 541-019927 event on 2023 Sep 10, 01:24 UT Visible from Europe, N Africa Summary ------- On 2023 Sep 10 UT, the 108 km diameter asteroid (5) Astraea will occult a 12.0 mag star in the constellation Orion for observers along a path across Europe, N Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.68 mag to 11.90 mag (the magnitude of the asteroid) for at most 4.410 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.
