Visible from S China, SE Asia, India
Summary
-------
On 2011 Jul 06 UT, the 12 km diameter asteroid (1188) Gothlandia will occult a
9.8 mag star in the constellation Pisces for observers along a path across S
China, SE Asia, India.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 5.3 mag to 15.1 mag (the magnitude of the asteroid) for at most 0.8
seconds.
This update is based on UNSO/Flagstaff astrometry for the asteroid kindly
provided by Hugh Harris, historical astrometry from the MPC files (via AstDys),
and the following catalogs for the star position: UCAC.
