IOTA/IOTA-ES occultation update for (1081) Reseda / HIP 17608 event on 2021 Jan 25, 22:33 UT Visible from Africa Summary ------- On 2021 Jan 25 UT, the 36.7 km diameter asteroid (1081) Reseda will occult a 4.1 mag star in the constellation Taurus for observers along a path across Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.94 mag to 8.00 mag (the combined magnitude of the asteroid and the close companion star) for at most 6.0 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).
