IOTA/IOTA-ES occultation update for (227) Philosophia / UCAC4 462-128166 event on 2022 Jun 16, 08:10 UT Visible from South America Summary ------- On 2022 Jun 16 UT, the 96.6 km diameter asteroid (227) Philosophia will occult a 11.6 mag star in the constellation Pisces for observers along a path across South America. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.57 mag to 15.13 mag (the magnitude of the asteroid) for at most 5.580 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.
