Asteroid occultation event on 2019 January 22

I've prepared finder charts from:
Digital Sky Survey (15 x 15 arcmin and 30 x 30 arcmin) and The Sky 6 (15x11 arcmin)

IOTA/IOTA-ES occultation update for
(2) Pallas / UCAC4-432-057458 event on 2019 Jan 22, 21:34 UT
Visible from SE Asia


Summary
-------
On 2019 Jan 22 UT, the 572.3 km diameter asteroid (2) Pallas will occult a 12.2
mag star in the constellation Virgo for observers along a path across SE Asia.

In the case of an occultation, the combined light of the asteroid and the star
will drop by 0.05 mag to 8.75 mag (the magnitude of the asteroid) for at most
31.2 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.
