IOTA/IOTA-ES occultation update for (98943) 2001 CC21 / UCAC4 622-031787 event on 2024 Apr 21, 10:42 UT Visible from Summary ------- On 2024 Apr 21 UT, the 0.603 km diameter asteroid (98943) 2001 CC21 will occult a 13.1 mag star in the constellation Auriga for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 6.68 mag to 19.82 mag (the magnitude of the asteroid) for at most 0.170 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.
