Asteroid occultation event on 2019 April 19

I've prepared finder charts from:
Digital Sky Survey (15 x 15 arcmin) and The Sky 6 (15x11 arcmin)
---------------------------------------------------------------------------------------------------

IOTA/IOTA-ES occultation update for
(345) Tercidina / TYC 5755-00447-1 event on 2019 Apr 19, 19:18 UT
Visible from Japan, China


Summary
-------
On 2019 Apr 19 UT, the 98.6506464917348 km diameter asteroid (345) Tercidina
will occult a 9.3 mag star in the constellation Capricornus for observers along
a path across Japan, China.

In the case of an occultation, the combined light of the asteroid and the star
will drop by 4.46 mag to 13.76 mag (the magnitude of the asteroid) for at most
4.4 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.

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.
