IOTA/IOTA-ES occultation update for (404) Arsinoe / UCAC4 553-009906 event on 2023 Mar 25, 03:12 UT Visible from Canada, USA Summary ------- On 2023 Mar 25 UT, the 95.4 km diameter asteroid (404) Arsinoe will occult a 10.9 mag star in the constellation Taurus for observers along a path across Canada, USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 3.97 mag to 14.88 mag (the magnitude of the asteroid) for at most 3.520 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.
