Jan Manek's update
IOTA/IOTA-ES occultation update for
(415) Palatia / TYC 1371-01852-1 on January 24/25, 2003
visible from India, S Pakistan, Iran, SW Russia, Estonia
SW Finland, N Sweden and Norway
Summary
In the night of January 24/25, 2003 a faint 10.7 mag star TYC 1371-01852-1
will be occulted by a 80 km asteroid (415) Palatia. This update is based on
USNO/Flagstaff astrometry for the asteroid and recent UCAC star position.
The updated path shows ~2 path width east shift with time 0.1 minutes later compared to
Edwin Goffin's nominal prediction.
Updated path runs over India around 22:18.5 UT, S Pakistan ~22:20 UT, Iran around 22:22 UT,
SW Russia ~23:24 to 23:28 UT, Estonia, ~23:28.3 UT, SW Finland ~23:28.6 UT with Helsinki in path, N Sweden ~23:29.7 UT
and Norway ~23:30 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.
Close finding chart (prepared in GUIDE7):
