    Summary 

    In the night of November 18/19, 2002 a 9.6 mag star TYC 3358-00173-1 will be occulted by a 58 km asteroid (1049) Gotho. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and Tycho-2 position.

    The updated path shows ~6 path width west shift with time correction +1.3 minutes compared to Edwin Goffin's nominal prediction.

    Updated path runs over Japan ~19:55 UT, China ~19:57 UT, far East and Siberia ~19:59->20:03 UT, N Russia ~20:04->20:06 UT, Finland ~20:06.6 UT, S Sweden ~20:07.6 UT, very S Norway ~20:08.0 UT and England ~20:09.0 UT. Please check the path chart for details.

    Clear sky and good luck !!!

        !!! IMPORTANT !!!
        Purple stars in identification chart are so called 'non-star' objects in GSC; in dense fields
        the 'non-stars' are often real stars or blends of close pairs. Be careful about this.
