IOTA/IOTA-ES occultation update for (284) Amalia / UCAC4 510-037700 event on 2022 Feb 03, 06:52 UT Visible from USA Summary ------- On 2022 Feb 03 UT, the 56.8 km diameter asteroid (284) Amalia will occult a 12.3 mag star in the constellation Canis Minor 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 2.41 mag to 14.63 mag (the magnitude of the asteroid) for at most 4.710 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.
