Asteroid occultation event on 2019 January 20

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
(671) Carnegia / UCAC4-623-036921 event on 2019 Jan 20, 20:38 UT
Visible from China, SW Asia, Africa


Summary
-------
On 2019 Jan 20 UT, the 61.3 km diameter asteroid (671) Carnegia will occult a
11.8 mag star in the constellation Gemini for observers along a path across
China, SW Asia, Africa.

In the case of an occultation, the combined light of the asteroid and the star
will drop by 2.81 mag to 14.52 mag (the magnitude of the asteroid) for at most
5.7 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.
