IOTA/IOTA-ES occultation update for (61) Danae / UCAC4-655-046340 event on 2022 Jan 27, 03:52 UT Visible from Africa, USA, Mexico Summary ------- On 2022 Jan 27 UT, the 81.7 km diameter asteroid (61) Danae will occult a 12.2 mag star in the constellation Auriga for observers along a path across Africa, USA, Mexico. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.95 mag to 12.58 mag (the magnitude of the asteroid) for at most 6.040 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.
