IOTA/IOTA-ES occultation update for (41) Daphne / UCAC4 456-019244 event on 2021 Jan 16, 01:31 UT Visible from S USA Summary ------- On 2021 Jan 16 UT, the 186.1 km diameter asteroid (41) Daphne will occult a 13.7 mag star in the constellation Monoceros for observers along a path across S USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.20 mag to 11.93 mag (the magnitude of the asteroid) for at most 13.5 seconds.
