IOTA/IOTA-ES occultation update for (874) Rotraut / TYC 0043-00490-1 event on 2021 Jan 27, 21:41 UT Visible from Europe Summary ------- On 2021 Jan 27 UT, the 57 km diameter asteroid (874) Rotraut will occult a 11.4 mag star in the constellation Cetus for observers along a path across Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 4.85 mag to 16.24 mag (the magnitude of the asteroid) for at most 3.3 seconds.
