IOTA/IOTA-ES occultation update for (41) Daphne / TYC 0133-01056-1 event on 2021 Jan 18, 04:08 UT Visible from South America Summary ------- On 2021 Jan 18 UT, the 186.1 km diameter asteroid (41) Daphne will occult a 10.7 mag star in the constellation Monoceros for observers along a path across South America. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.55 mag to 11.95 mag (the magnitude of the asteroid) for at most 13.7 seconds.
