IOTA/IOTA-ES occultation update for (205) Martha / UCAC4 514-018989 event on 2023 Nov 11, 15:53 UT Visible from Japan, SE Asia Summary ------- On 2023 Nov 11 UT, the 81.3 km diameter asteroid (205) Martha will occult a 10.7 mag star in the constellation Orion for observers along a path across Japan, SE Asia. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.19 mag to 13.87 mag (the magnitude of the asteroid) for at most 11.090 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.
