IOTA/IOTA-ES occultation update for (65803) Didymos / HIP 37693 event on 2023 Jan 01, 01:13 UT Visible from SW Asia, Europe, E Canada, N USA Summary ------- On 2023 Jan 01 UT, the 0.780881857921375 km diameter asteroid (65803) Didymos will occult a 9.0 mag star in the constellation Gemini for observers along a path across SW Asia, Europe, E Canada, N USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 7.47 mag to 16.44 mag (the magnitude of the asteroid) for at most 0.250 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.
