IOTA/IOTA-ES occultation update for (122) Gerda / TYC 0625-00141-1 event on 2023 Oct 24, 07:32 UT Visible from E Canada, USA Summary ------- On 2023 Oct 24 UT, the 78 km diameter asteroid (122) Gerda will occult a 11.0 mag star in the constellation Pisces for observers along a path across E Canada, USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.47 mag to 12.18 mag (the magnitude of the asteroid) for at most 5.780 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.
