IOTA/IOTA-ES occultation update for (709) Fringilla / UCAC4 509-146985 event on 2023 Sep 20, 02:46 UT Visible from Europe, Canada, N USA Summary ------- On 2023 Sep 20 UT, the 98.2 km diameter asteroid (709) Fringilla will occult a 13.9 mag star in the constellation Pegasus for observers along a path across Europe, Canada, N USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.32 mag to 12.71 mag (the magnitude of the asteroid) for at most 8.480 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.
