    Summary 

    In the night of February 8/9, 2004 a faint 12.1 mag star TYC 0810-02126-1 will be occulted by a 61 km asteroid (119) Althaea. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.

    The updated path shows ~4 path widths south shift with time 0.2 minutes later compared to Edwin Goffin's nominal prediction.

    Updated path runs over India around 22:59.5 UT, Iraq ~23:03 UT, middle East ~23:04.0 UT, Cyprus ~23:04.4 UT, SW Turkey ~23:04.8 UT, Greece ~23:05.8 UT, S Albania ~23:06.1 UT, Italy from SE to NW around 23:07 UT and France from SE to NW around 23:08.1 UT. Please check the path chart for details.

    Here is current station list for European cities and observatories plus other sites.

     * occulted star is in center - labeled with cross
     * labeled stars have indicated SAO numbers
     * square box shows 30' field in all wider field charts
     * remarks:
       Target star is in south Cancer, about 2.8 degrees N of 3.4 mag star epsilon Hydrae = SAO 117112.
       Target star is ~6' south of double star J2063 (9.3+11.0, PA 115, sep. ~7").
       !!! 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.
