IOTA/IOTA-ES occultation update for (726) Joella / UCAC4-512-008209 event on 2019 Feb 22, 17:29 UT Visible from China, Russia, Europe Summary ------- On 2019 Feb 22 UT, the 45.6 km diameter asteroid (726) Joella will occult a 9.9 mag star in the constellation Orion for observers along a path across China, Russia, Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 5.47 mag to 15.32 mag (the magnitude of the asteroid) for at most 3.3 seconds.
