IOTA/IOTA-ES occultation update for (128) Nemesis / UCAC4 561-047042 event on 2023 Nov 03, 07:19 UT Visible from Europe, Canada, USA Summary ------- On 2023 Nov 03 UT, the 175 km diameter asteroid (128) Nemesis will occult a 11.9 mag star in the constellation Cancer for observers along a path across Europe, Canada, USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.29 mag to 12.83 mag (the magnitude of the asteroid) for at most 13.190 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.
