IOTA/IOTA-ES occultation update for (174) Phaedra / TYC 2353-01481-1 event on 2023 Nov 14, 21:00 UT Visible from SE Asia, India, Africa Summary ------- On 2023 Nov 14 UT, the 66.1 km diameter asteroid (174) Phaedra will occult a 10.5 mag star in the constellation Perseus for observers along a path across SE Asia, India, Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.74 mag to 13.16 mag (the magnitude of the asteroid) for at most 4.520 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.
