IOTA/IOTA-ES occultation update for
(726) Joella / UCAC4 366-065130 event on 2021 Jun 19, 13:36 UT
Visible from Australia, China
Summary
-------
On 2021 Jun 19 UT, the 45.2 km diameter asteroid (726) Joella will occult a
12.1 mag star in the constellation Libra for observers along a path across
Australia, China.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 3.00 mag to 15.04 mag (the magnitude of the asteroid) for at most
6.2 seconds.
This update is based on, astrometry for the asteroid kindly provided by the IAU
Minor Planet Center.
This work has made use of data from the European Space Agency (ESA)
mission Gaia (http://www.cosmos.esa.int/gaia), processed by the
Gaia Data Processing and Analysis Consortium
(DPAC, http://www.cosmos.esa.int/web/gaia/dpac/consortium).
Funding for the DPAC has been provided by national institutions, in
particular the institutions participating in the Gaia Multilateral Agreement.
