IOTA/IOTA-ES occultation update for
(94) Aurora / TYC 1947-00021-1 on January 25/26, 2004
visible from Russia, E Ukraine, E Belarus, E Lithuania, Latvia,
W Estonia, middle Sweden, mid-south Norway, greenland and Canada
Summary
In the night of January 25/26, 2004 a faint 11.7 mag star TYC 1947-00021-1 will be occulted by a 212 km asteroid (94) Aurora. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.
The updated path shows ~0.6 path widths north shift with time 0.2 minutes earlier compared to Edwin Goffin's nominal prediction.
Updated path runs over Russia from S nto NW ~2:41 to 2:42.8 UT, E Ukraine ~2:41.6 UT, E Belarus ~2:42.3 UT, E Lithuania ~2:42.6 UT, Latvia ~242.7 UT, W Estonia ~2:42.9 UT, middle Sweden ~2:43.5 UT, mid-south Norway ~2:43.9 UT, Greenland ~2:47 UT and Canada around 2:50 UT. Please check the path chart for details.
Here is current station list for European cities.
Clear sky and good luck !!!

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 north Cancer, about 3.8 degrees east of 4.0 mag star iota Cancri = SAO 80416.
!!! 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.
