IOTA/IOTA-ES occultation update for (2376) Martynov / UCAC4 438-56847 event on 2020 Dec 31, 03:29 UT Visible from Europe Summary ------- On 2020 Dec 31 UT, the 41.3 km diameter asteroid (2376) Martynov will occult a 9.1 mag star in the constellation Virgo 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 8.07 mag to 17.17 mag (the magnitude of the asteroid) for at most 2.5 seconds.
