IOTA/IOTA-ES occultation update for
(372) Palma / TYC 0562-01044-1 on October 12/13, 2005
visible from S Russia, Ukraine, S Poland, N Slovakia, Czechia,
middle Germany, Luxembourg, Belgium, N France and S England
Summary
In the night of October 12/13, 2005 a faint 12.4 mag star TYC 0562-01044-1 will be occulted by a 195 km asteroid (372) Palma. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.
The updated path shows ~0.6 path width south shift with time ~1.7 minutes earlier compared to Edwin Goffin's nominal prediction.
Updated path runs over S Russia ~21:34 UT, Ukraine ~21:35.0 UT, S Poland ~21:36.5 UT, N Slovakia ~21:36.4 UT, Czechia ~21:37.0 UT, middle Germany ~21:37.8 UT, Luxembourg ~21:38.3 UT, Belgium ~21:38.5 UT, N France ~21:38.8 UT and S England ~21:39.5 UT. Please check the path chart for details.

Finding charts (prepared in GUIDE8):
* occulted star is in center - labeled with cross
* labeled stars have indicated SAO numbers
* (smaller) square box shows 30' field in all wider field charts
* (larger) square box shows 3° field in wide field charts
* remarks:
Target star is in SW Pegasus, about 2.8 degrees SSE of 3.5 mag star theta Pegasi = SAO 127340.
!!! 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.
