                  IOTA/IOTA-ES occultation update for
        (231) Vindobona / TYC 2389-01522-1 on December 13/14, 2003
       visible from Egypt, Malta, Mallorca, Spain, E Canada and USA


Summary

In the night of December 13/14, 2003 a faint 11.1 mag star TYC 2389-01522-1 will be occulted by a 85 km asteroid (231) Vindobona. This update is based on USNO/Flagstaff astrometry for the asteroid and UCAC2 star position.

The updated path shows ~9 path width north shift with time 0.7 minutes earlier compared to Edwin Goffin's nominal prediction.

Updated path runs due to north shift over Egypt 3:28.1 UT, Malta ~3:28.9 UT, Mallorca ~3:29.6 UT, Spain around 3:30.1 UT, E Canada ~3:35 UT and USA from NE to SW at 3:36 to 3:39 UT. Please check the path chart for details.

Here is current station list for observers and European cities.

Clear sky and good luck !!!

The event at one glimpse: * date and approx.

Data for the target star: * name: TYC 2389-01522-1 * constellation: Auriga * J2000 position [h,m,s; o,',"]: 05h 13m 24.7559s; +30o 13' 21.337" * position source: UCAC2 * estimated accuracy ["]: 0.03" (0.02", 0.02") * V mag [mag]: 11.05 * B-V [mag]: +1.16 * remarks: Target star is in south Auriga, about 3.2 degrees northwest of 1.7 mag star beta Tauris = SAO 77168. !!! 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 GUIDE8): * occulted star is in center - labeled with cross * field is 3.0x3.0 degrees * limiting magnitude is 12.5 * labeled stars have indicated SAO numbers * remarks: Second chart shows 3 degrees blowup to show correctly the star in field.
