IOTA/IOTA-ES occultation update for (738) Alagasta / TYC 1338-01759-1 event on 2023 Dec 22, 23:11 UT Visible from Africa, India Summary ------- On 2023 Dec 22 UT, the 61 km diameter asteroid (738) Alagasta will occult a 10.6 mag star in the constellation Gemini for observers along a path across Africa, India. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.75 mag to 14.31 mag (the magnitude of the asteroid) for at most 4.790 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.
