IOTA/IOTA-ES occultation update for (127) Johanna / TYC 0645-01001-1 event on 2023 Aug 21, 10:09 UT Visible from Canada, USA Summary ------- On 2023 Aug 21 UT, the 125.3 km diameter asteroid (127) Johanna will occult a 9.9 mag star in the constellation Aries for observers along a path across Canada, USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.83 mag to 13.68 mag (the magnitude of the asteroid) for at most 14.260 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.
