Jan Manek's update
IOTA/IOTA-ES occultation update for
(510) Mabella / TYC 0789-01787-1 on April 26/27, 2003
visible from Scotland, S Denmark, N Germany, N Poland,
S Belarus, NE Ukraine and S Russia
Summary
In the night of April 26/27, 2003 a faint 10.8 mag star TYC 0789-01787-1
will be occulted by a 59 km asteroid (510) Mabella. 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 south shift with time ~0.1 minute later compared to
Edwin Goffin's nominal prediction.
Updated path runs over Scotland ~21:06.2 UT with Glasgow in path, S Denmark ~21:06.6 UT, N Germany ~21:06.8,
N Poland ~21:07.1 UT, S Belarus ~21:07.4 UT, NE Ukraine ~21:07.6 UT and S Russia ~21:07.7 UT at low altitudes.
Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: April 26, 2003 @ 21:07 UT (Europe)
* magnitude of target star: 10.8
* magnitude drop [mag]: 4.7
* estimated maximum duration [s]: 3.5
* path description: given above
* Goffin's original chart reference: A03_0443
The occultation path:
* approximate ground width [km]: 85

* uncertainty in time [s]: 6
* 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 0789-01787-1
* constellation: Cancer
* J2000 position [h,m,s; o,',"]: 08h 05m 11.3920s; +11o 27' 17.708"
* position source: recent UCAC position combined with Tycho-2 proper motion
* estimated accuracy ["]: 0.02" (0.02", 0.01")
* V mag [mag]: 10.79
* B-V [mag]: +0.58
* remarks:
Target star is in southwest Cancer, about 3.6 degrees NW of 3.5 mag star beta Cancri = SAO 116569 or
12' north of 8.6 mag star SAO 97544.
!!! 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 GUIDE8):
* 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
* remarks: Second chart shows 30' blowup to show correctly the star in Milky Way field.
