IOTA/IOTA-ES occultation update for
(241) Germania / HIP 50299 = SAO 118193 on February 10/11, 2004
visible from N Turkey, Bulgaria, S Romania, frm.Yugoslavia, Slovenia, NE Italy,
SW Austria, Switzerland, SW Germany, N France, SW England and SW Ireland
Summary
In the night of February 10/11, 2004 a bright 8.6 mag star HIP 50299 = SAO 118193 will be occulted by a 169 km asteroid (241) Germania. This update is based on USNO/Flagstaff and TMO astrometry for the asteroid and Hipparcos star position.
The updated path shows ~1.5 path widths north shift with time 0.8 minutes earlier compared to Edwin Goffin's nominal prediction.
Updated path runs over N Turkey ~4:01 UT, Bulgaria ~4:01.5 UT, S Romania ~4:01.6 UT, frm.Yugoslavia ~4:01.8 UT, Slovenia ~4:02.1 UT, NE Italy ~4:02.2 UT, SW Austria ~4:02.3 UT, Switzerland ~4:02.5 UT, SW Germany ~4:02.6 UT, N France ~4:02.9 UT, SW England ~4:03.5 UT and SW Ireland ~4:03.9 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 north Sextant, about 8.6 degrees SSE of 1.4 mag star alpha Leonis = Regulus = SAO 98967.
!!! 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.
