Jan Manek's update
IOTA/IOTA-ES occultation update for
(366) Vincentina / TYC 2411-00003-1 on February 11/12, 2003
visible from Serbia, Slovenia, N Italy, Switzerland, middle France
and east Brasil
Summary
In the night of February 11/12, 2003 a faint 11.6 mag star TYC 2411-00003-1
will be occulted by a 98 km asteroid (366) Vincentina. This update is based on
USNO/Flagstaff and TMO astrometry for the asteroid and recent UCAC star position.
The updated path shows ~1 path width NW shift with time 0.7 minutes later compared to
Edwin Goffin's nominal prediction.
Updated path runs over Serbia ~1:50.0 UT, Slovenia ~1:50.5 UT, N Italy ~1:51.0 UT, Switzerland ~1:51.4 UT,
middle France ~1:52.0 UT and east Brasil 2:11-2:13 UT.
Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: February 12, 2003 @ 01:51 UT (Europe)
02:12 UT (Brasil)
* magnitude of target star: 11.6
* magnitude drop [mag]: 2.6
* estimated maximum duration [s]: 17.4
* path description: given above
* Goffin's original chart reference: A03_0229
The occultation path:
* approximate ground width [km]: 150
* uncertainty [path widths]: 1.0
* uncertainty in time [s]: 20
* map: below
* remarks: Path uncertainties are given according to nominal star
position errors and expected asteroid positional accuracy.
Data for the target star:
* name: TYC 2411-00003-1
* constellation: Auriga
* J2000 position [h,m,s; o,',"]: 05h 25m 56.1371s; +35o 18' 29.568"
* position source: recent UCAC position combined with Tycho-2 proper motion
* estimated accuracy ["]: 0.02" (0.01", 0.01")
* V mag [mag]: 11.59
* B-V [mag]: +0.18
* remarks:
Target star is in mid-south Auriga, about 6.6 degrees north of 1.7 mag star beta Tauri = SAO 77168 or
0.8 degree SW of open cluster M38.
!!! 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 GUIDE7):
* occulted star is in center - labeled with cross
* field is 2.0x2.0 degrees
* limiting magnitude is 13.0
* labeled stars have indicated SAO numbers
* remarks: Second chart shows 30' blowup to show correctly the star in Milky Way field.
