Jan Manek's update
IOTA/IOTA-ES occultation update for
(1107) Lictoria / TYC 1898-00944-1 on March 9, 2002
visible from NW Spain, middle France, Switzerland, S Germany,
Austria, Slovakia, Ukraine, S Russia, Khazachstan and China
Summary
In the evening of March 9, 2002 a 11.4 mag star TYC 1898-00944-1
will be occulted by a 81 km asteroid (1107) Lictoria. This update is based on
USNO/Flagstaff astrometry for the asteroid and UCAC star position.
The updated path shows ~9 path width north shift with time ~0.1 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over very NW Spain ~19:00.5 UT, France from SW to NE - just north of Bordeaux ~19:02 UT,
Limoges is in path ~19:02.6 UT, Clermont-Ferrand is on south limit ~19:03 UT while Besancon is on north limit
~19:03.7 UT, north Switzerland follows with Bern and Zurich in path, south Germany with Munich on north limit ~19:05 UT,
north Austria with Vienna on central line around 19:05.9 UT, whole Slovakia around ~19:06.5 UT, Ukraine from east to west
from 19:07 to 19:10 UT, south Russia ~19:11 UT with Volgograd in path. Follows Khazachstan with Alma-Ata ~19:16.5 UT and
finally China 19:17-19:19 UT.
Larger area is covered taking uncertainty into consideration.
Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: March 9, 2002 @ 19:05 UT (Euro)
* magnitude of target star: 11.4
* magnitude drop [mag]: 2.7
* estimated maximum duration [s]: 13.3
* path description: given above
* Goffin's original chart reference: A02_0343
The occultation path:
* approximate ground width [km]: 90
* uncertainty [path widths]: 1.6
* uncertainty in time [s]: 25
* 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 1898-00944-1
* constellation: Gemini
* J2000 position [h,m,s; o,',"]: 06h 52m 21.4382s; +24o 26' 36.953"
* position source: UCAC combined with Tycho-2 proper motion
* estimated accuracy ["]: 0.014" (0.010", 0.010")
* V mag [mag]: 11.44
* B-V [mag]: +0.39
* remarks:
Recent UCAC position was provided by Marion and Norbert Zacharias.
Target star is in middle Gemini, about 2 degrees ESE of 3.0 mag epsilon Geminorum = SAO 78682.
About 50' south of target is 5.7 mag star SAO 78816. It is a dense star field, be sure to
have enough time to locate the correct star. 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.
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
