IOTA/IOTA-ES occultation update for (737) Arequipa / UCAC4 473-126428 event on 2024 Jul 17, 13:55 UT Visible from Summary ------- On 2024 Jul 17 UT, the 45.823 km diameter asteroid (737) Arequipa will occult a 12.0 mag star in the constellation Equuleus for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 0.50 mag to 11.37 mag (the magnitude of the asteroid) for at most 12.230 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.
