Jan Manek's update
IOTA/IOTA-ES occultation update for
(509) Iolanda / TYC 0110-00178-1 on December 28/29, 2002
visible from Khazachtan, S Russia, Crymean peninsula, Romania,
frm. Yugoslavia, mid-north Italy, S France, N Spain, N Portugal and Florida
Summary
In the night of December 28/29, 2002 a faint 12.2 mag star TYC 0110-00178-1
will be occulted by a 59 km asteroid (509) Iolanda. This update is based on
USNO/Flagstaff and TMO astrometry for the asteroid and recent UCAC star position.
The updated path shows ~10 path width south shift with time 0.3 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over Khazachtan ~22:44 UT, S Russia ~22:45 UT, Crimean peninsula 22:46 UT, Romania ~22:47 UT,
frm. Yugoslavia ~22:47.6 UT with Belgrade in path, mid-north Italy ~22:48.5 UT, S France ~22:49 UT with Nice and Marseille on north limit,
N Spain ~22:50 UT, N Portugal ~22:50.9 UT with Porto in path and finally south Florida ~22:58.6 UT in evening twilight.
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):
