IOTA/IOTA-ES occultation update for (403) Cyane / TYC 0743-01251-1 event on 2021 Feb 08, 23:28 UT Visible from Africa, E USA Summary ------- On 2021 Feb 08 UT, the 48.1 km diameter asteroid (403) Cyane will occult a 13.2 mag star in the constellation Orion for observers along a path across Africa, E USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.68 mag to 13.06 mag (the magnitude of the asteroid) for at most 14.4 seconds.
