Jan Manek's update
IOTA/IOTA-ES occultation update for
(663) Gerlinde / TYC 4814-00668-1 = SAO 134182 on February 13/14, 2003
visible from India, middle East, Cyprus, SW Turkey, NE Greece, Macedonia,
S Serbia, Bosna, Croatia, Slovenia, NE Italy, W Austria, SW Germany,
very NE France, Belgium, England and north Ireland
Summary
In the night of February 13/14, 2003 a bright 9.0 mag star TYC 4814-00668-1 = SAO 134182
will be occulted by a 104 km asteroid (663) Gerlinde. This update is based on
USNO/Flagstaff and TMO astrometry for the asteroid and recent UCAC star position.
The updated path shows large ~1" SW shift with time 2.4 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over India ~19:33.5 UT, middle East ~19:42.5 UT, Cyprus ~19:435 UT, SW Turkey ~19:44.5 UT,
NE Greece ~19:45.6 UT, Macedonia ~19:46.0 UT, S Serbia ~19:46.4 UT, Bosnia ~19:46.7 UT, Croatia ~19:47.0 UT,
Slovenia ~19:47.3 UT, very NE Italy ~19:47.6 UT, W Austria ~19:47.6 UT, SW Germany ~19:48.0 UT with Munich just north of path,
very NE France ~19:48.4 UT with Strasbourg and Lille in path, Belgium ~19:48.7 UT with Brussels in path, England ~19:49.5 UT
with London on south limit and Liverpool in path and finally north Ireland ~19:50.0 UT.
Please check the path chart for details.
Almost full Moon is exactly north of target star making target star location bit harder.
However I count this as a favorable event due to bright star, low uncertainty, good path location,
long event duration and large brightness drop.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: February 12, 2003 @ 19:33 UT (India)
19:47 UT (Europe)
* magnitude of target star: 9.0
* magnitude drop [mag]: 4.7
* estimated maximum duration [s]: 13.4
* path description: given above
* Goffin's original chart reference: A03_0244
The occultation path:
* approximate ground width [km]: 125
* uncertainty [path widths]: 0.9
* uncertainty in time [s]: 12
* 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 4814-00668-1 = SAO 134182 = PPM 176667
* constellation: Monoceros
* J2000 position [h,m,s; o,',"]: 07h 06m 02.2698s; -01o 18' 13.146"
* position source: recent UCAC position combined with Tycho-2 proper motion
* estimated accuracy ["]: 0.02" (0.01", 0.02")
* V mag [mag]: 9.01
* B-V [mag]: +0.02
* remarks:
Target star is in middle Monoceros, about 1.7 degrees SW of 4.1 mag star delta Monocerotis = SAO 134330 or
8' SE of 7.8 mag star SAO 134173.
!!! 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 3.0x3.0 degrees
* limiting magnitude is 12.0
* labeled stars have indicated SAO numbers
* remarks: Second chart shows 30' blowup to show correctly the star in Milky Way field.
Data for the minor planet:
