IOTA/IOTA-ES occultation update for (1994) Shane / HIP 28166 event on 2023 Aug 31, 08:24 UT Visible from Canada, W USA Summary ------- On 2023 Aug 31 UT, the 21.2873770367242 km diameter asteroid (1994) Shane will occult a 5.6 mag star in the constellation Orion for observers along a path across Canada, W USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 12.07 mag to 17.67 mag (the magnitude of the asteroid) for at most 1.660 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.
