IOTA/IOTA-ES occultation update for (381) Myrrha / UCAC4 400-073020 event on 2022 May 28, 05:55 UT Visible from USA, SE Canada Summary ------- On 2022 May 28 UT, the 124.8 km diameter asteroid (381) Myrrha will occult a 13.8 mag star in the constellation Ophiuchus for observers along a path across USA, SE Canada. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.36 mag to 12.81 mag (the magnitude of the asteroid) for at most 12.780 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.
