IOTA/IOTA-ES occultation update for (1194) Aletta / UCAC4-614-020383 event on 2023 Oct 04, 10:16 UT Visible from SE Canada, USA, Mexico Summary ------- On 2023 Oct 04 UT, the 40.6 km diameter asteroid (1194) Aletta will occult a 12.3 mag star in the constellation Auriga 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 3.79 mag to 16.05 mag (the magnitude of the asteroid) for at most 6.290 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.
