IOTA/IOTA-ES occultation update for (2158) Tietjen / TYC 6230-00891-1 event on 2024 Apr 01, 08:58 UT Visible from Summary ------- On 2024 Apr 01 UT, the 22.226158149108 km diameter asteroid (2158) Tietjen will occult a 10.5 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 6.02 mag to 16.54 mag (the magnitude of the asteroid) for at most 3.740 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).
