IOTA/IOTA-ES occultation update for
(284) Amalia / TYC 0782-00761-1 on February 18/19, 2004
visible from Turkey, Bulgaria, Serbia, W Hungary, Austria,
Germany from SE to NW, S Netherlands, NE England and SW Scotland
Summary
In the night of February 18/19, 2004 a faint 11.0 mag star TYC 0782-00761-1 will be occulted by a 55 km asteroid (284) Amalia. This update is based on USNO/Flagstaff astrometry for the asteroid and UCAC2 star position.
The updated path shows no path shift with time 0.4 minutes later compared to Edwin Goffin's nominal prediction.
Updated path runs over Turkey ~23:10.0UT, Bulgaria ~23:11.3 UT, Serbia ~23:11.9 UT, W Hungary ~23:12.4 UT, Austria ~23:12.8 UT, Germany from SE to NW around 23:13.4 UT, S Netherlands ~23:14.0, NE England ~23:14.8 UT and SW Scotland ~23:15.3 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
* square box shows 30' field in all wider field charts
* remarks:
Target star is in N Canis Minor, about 5.0 degrees north of 0.5 mag star alpha Canis Minoris = Procyon = SAO 115756.
!!! 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.
