IOTA/IOTA-ES occultation update for (196) Philomela / UCAC4 592-042146 event on 2021 Jan 20, 17:42 UT Visible from Japan, China, Russia, Europe Summary ------- On 2021 Jan 20 UT, the 140.1 km diameter asteroid (196) Philomela will occult a 12.5 mag star in the constellation Gemini for observers along a path across Japan, China, Russia, Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.25 mag to 10.99 mag (the magnitude of the asteroid) for at most 10.3 seconds. This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, astrometry for the asteroid kindly provided by Bill Owen, 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).
