IOTA/IOTA-ES occultation update for (1128) Astrid / UCAC4-330-104973 event on 2023 Sep 06, 13:20 UT Visible from Australia Summary ------- On 2023 Sep 06 UT, the 41.8 km diameter asteroid (1128) Astrid will occult a 12.4 mag star in the constellation Ophiuchus 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 3.56 mag to 15.92 mag (the magnitude of the asteroid) for at most 3.410 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.
