IOTA/IOTA-ES occultation update for (1446) Sillanpaa / TYC 1240-00340-1 event on 2024 Jul 27, 07:01 UT Visible from Summary ------- On 2024 Jul 27 UT, the 8.03966976792534 km diameter asteroid (1446) Sillanpaa will occult a 10.3 mag star in the constellation Aries for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 7.46 mag to 17.77 mag (the magnitude of the asteroid) for at most 0.330 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.
