Jan Manek's update
IOTA/IOTA-ES occultation update for
(582) Olympia / TYC 5452-01110-1 = SAO 154849 on January 13/14, 2003
visible from NE Africa, Egypt, E Greece, W Bulgaria, E Serbia,
W Romania, E Hungary, E Slovakia, Poland and N Sweden
Summary
In the night of January 13/14, 2003 a bright 8.8 mag star TYC 5452-01110-1 = SAO 154849
will be occulted by a 47 km asteroid (582) Olympia. This update is based on
USNO/Flagstaff and TMO astrometry for the asteroid and Tycho-2 star position.
The updated path shows ~11 path width east shift with time 0.1 minutes earlier compared to
Edwin Goffin's nominal prediction.
Updated path runs over NE Africa, Egypt around 01:10 UT~, E Greece ~01:12.4 UT, W Bulgaria ~01:12.6 just west of Sofia,
E Serbia ~01:13.0 UT, W Romania ~01:13.3 UT, E Hungary ~01:13.5 UT with Debrecen in path, E Slovakia 01:13.6 UT with
Kosice in path, Poland around 01:14.0 UT with path running between Warszawa and Lodz. And finally N Sweden ~01:15.2 UT.
Please check the path chart for details.
Good event, worth of travel effort. As the event lasts only ~5 seconds, video is recommended.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: January 14, 2003 @ 01:14 UT (Europe)
* magnitude of target star: 8.8
* magnitude drop [mag]: 3.2
* estimated maximum duration [s]: 4.9
* path description: given above
* Goffin's original chart reference: A03_0149
The occultation path:
* approximate ground width [km]: 65
* uncertainty [path widths]: 1.8
* uncertainty in time [s]: 9
* map: below
* remarks: Path uncertainties are given according to nominal star
position errors and expected asteroid positional accuracy.
Data for the target star:
* name: SAO 154849 = PPM 220957 = TYC 5452-01110-1
* constellation: Hydra
* J2000 position [h,m,s; o,',"]: 09h 01m 42.6025s; -11o 15' 31.71 "
* position source: Tycho-2 including parallax
* estimated accuracy ["]: 0.02" (0.01", 0.02")
* V mag [mag]: 8.84
* B-V [mag]: +0.16
* remarks:
Target star is in Hydra, about 6.9 degrees SW of 2.0 mag star alpha Hydrae = SAO 136871.
Only 4' WNW of target star is another 8.3 mag star SAO 154842 forming nice pair.
!!! 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 12.5
* labeled stars have indicated SAO numbers
