IOTA/IOTA-ES occultation update for
(806) Gyldenia / UCAC4-345-072973 event on 2019 Jun 04, 15:08 UT
Visible from Taiwan, China, India
Summary
-------
On 2019 Jun 04 UT, the 71.1 km diameter asteroid (806) Gyldenia will occult a
11.5 mag star in the constellation Libra for observers along a path across
Taiwan, China, India.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 3.51 mag to 14.94 mag (the magnitude of the asteroid) for at most
6.8 seconds.
This update is based on UNSO/Flagstaff astrometry for the asteroid kindly

Owen, 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
