IOTA/IOTA-ES occultation update for (22978) Nyrola / TYC 6219-00010-1 event on 2024 Oct 11, 09:59 UT Visible from Summary ------- On 2024 Oct 11 UT, the 11.4082045417531 km diameter asteroid (22978) Nyrola will occult a 9.2 mag star in the constellation Ophiuchus for observers along a path across . In the case of an occultation, the combined light of the asteroid and the star will drop by 10.03 mag to 19.25 mag (the magnitude of the asteroid) for at most 0.370 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.
