IOTA/IOTA-ES occultation update for (34) Circe / UCAC4 374-101115 event on 2023 Jul 24, 06:36 UT Visible from SE Canada, USA, Mexico Summary ------- On 2023 Jul 24 UT, the 118.5 km diameter asteroid (34) Circe will occult a 11.8 mag star in the constellation Serpens for observers along a path across SE Canada, USA, Mexico. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.57 mag to 13.06 mag (the magnitude of the asteroid) for at most 15.690 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.
