IOTA/IOTA-ES occultation update for (115) Thyra / TYC 2330-00241-1 event on 2023 Jan 07, 17:23 UT Visible from India, Russia Summary ------- On 2023 Jan 07 UT, the 81.9 km diameter asteroid (115) Thyra will occult a 9.9 mag star in the constellation Perseus for observers along a path across India, Russia. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.29 mag to 10.77 mag (the magnitude of the asteroid) for at most 9.980 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.
