IOTA/IOTA-ES occultation update for (424) Gratia / HIP 7732 event on 2021 Jan 29, 21:00 UT Visible from Europe Summary ------- On 2021 Jan 29 UT, the 91.4 km diameter asteroid (424) Gratia will occult a 8.6 mag star in the constellation Pisces 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 6.15 mag to 14.71 mag (the magnitude of the asteroid) for at most 3.5 seconds. This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, astrometry for the asteroid kindly provided by Bill Owen, astrometry for the asteroid kindly provided by the IAU Minor Planet Center.
