Jan Manek's update
IOTA/IOTA-ES occultation update for
(759) Vinifera / TYC 5233-01441-1 on August 11/12, 2002
visible from India, Turkey, Romania, E Slovakia, Poland,
NE Germany and Denmark
Summary
In the night of August 11/12, 2002 a faint 11.0 mag star TYC 5233-01441-1
will be occulted by a 53 km asteroid (759) Vinifera. This update is based on
USNO/Flagstaff for the asteroid and recent UCAC star position.
The updated path shows ~6 path widths north shift with time ~0.4 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over India between 23:36 UT and 23:38 UT, followed by countries without observer and
heading to Europe. Around 23:43 UT path runs over Turkey, around 23:45 UT over NE Romania, very eastern tip
of Ukraine ~23:45.3 UT, east Slovakia ~23:45.5 UT, SW Poland ~23:46, NE Germany ~23:46.5 UT, Denmark ~23:46.8 UT
and finally also Iceland in twilight ~23:48.6 UT.
Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse:

23:45 UT (Europe)
* magnitude of target star: 11.0
* magnitude drop [mag]: 2.2
* estimated maximum duration [s]: 5.0
* path description: given above
* Goffin's original chart reference: A02_0843
The occultation path:
* approximate ground width [km]: 75
* uncertainty [path widths]: 1.8
* uncertainty in time [s]: 10
* 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 5233-01441-1
* constellation: Aquarius
* J2000 position [h,m,s; o,',"]: 22h 32m 08.9567s; -01o 12' 30.738"
* position source: UCAC combined with Tycho-2 proper motion
* estimated accuracy ["]: 0.02" (0.022", 0.008")
* V mag [mag]: 11.00
* B-V [mag]: +0.92
* remarks:
Recent UCAC position was provided by Marion and Norbert Zacharias.
Target star is in NE Aquarius, about 1.4 degrees southwest of 4.0 mag star eta Aquarii = SAO 146181.
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 13.0
* labeled stars have indicated SAO numbers
