IOTA/IOTA-ES occultation update for (1524) Joensuu / UCAC4 658-030549 event on 2022 Dec 09, 07:29 UT Visible from USA Summary ------- On 2022 Dec 09 UT, the 44.4 km diameter asteroid (1524) Joensuu will occult a 10.9 mag star in the constellation Auriga for observers along a path across USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.35 mag to 15.27 mag (the magnitude of the asteroid) for at most 3.360 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.
