Jan Manek's update
IOTA/IOTA-ES occultation update for
(301) Bavaria / TYC 4669-00528-1 on November 30, 2002
visible from Morocco, NW Algeria, S Sardegna, Italy, frm.Yugoslavia,
Romania and S Ukraine
Summary
In the evening of November 30, 2002 a faint 11.3 mag star TYC 4669-00528-1
will be occulted by a 56 km asteroid (301) Bavaria. This update is based on
USNO/Flagstaff and TMO astrometry for the asteroid and recent UCAC star position.
The updated path shows ~6 path width south shift with time 0.9 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over Morocco from SW to NE ~21:26->21:38 UT, NW Algeria ~21:39 UT, S Sardegna ~21:39.8 UT,
Italy south of Rome ~21:40.4 UT, frm.Yugoslavia ~21:41 UT, Romania just N of Bucharest ~21:41.3 UT and
S Ukraine ~21:41.7 UT with Odesa on north limit. 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.
Close finding chart (prepared in GUIDE7):
* occulted star is in center - labeled with cross
* field is 2.0x2.0 degrees
* limiting magnitude is 13.5
* labeled stars have indicated SAO numbers
