IOTA/IOTA-ES occultation update for (1687) Glarona / UCAC4 556-042668 event on 2022 Oct 25, 10:28 UT Visible from Canada Summary ------- On 2022 Oct 25 UT, the 36.2 km diameter asteroid (1687) Glarona will occult a 12.4 mag star in the constellation Gemini for observers along a path across Canada. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.53 mag to 15.87 mag (the magnitude of the asteroid) for at most 2.790 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.
