IOTA/IOTA-ES occultation update for (1330) Spiridonia / UCAC4 393-101886 event on 2023 Sep 23, 18:01 UT Visible from Africa Summary ------- On 2023 Sep 23 UT, the 64.8 km diameter asteroid (1330) Spiridonia will occult a 10.7 mag star in the constellation Scutum for observers along a path across Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 5.34 mag to 15.98 mag (the magnitude of the asteroid) for at most 5.280 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.
