IOTA/IOTA-ES occultation update for
(34) Circe / TYC 0745-01060-1 on January 5/6, 2004
visible from Siberia, N Russia, Finland, Sweden and Norway
Summary
In the night of January 5/6, 2004 a faint 10.7 mag star TYC 0745-01060-1 will be occulted by a 118 km asteroid (34) Circe. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and UCAC2 star position.
The updated path shows ~0.5 path width north shift with time 0.5 minutes later compared to Edwin Goffin's nominal prediction.
Updated path runs due to north shift over N Japan ~20:27.5 UT, NE China ~20:28.2 UT, NE Mongolia ~20:29.4 UT, Siberia ~20:30-20:34.0 UT, Russia around 20:35 UT, S Finland ~20:36.7 UT, middle Sweden ~20:37.6 UT and S Norway ~20:38.0 UT. Please check the path chart for details.
Here is current station list for European cities.
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.
