Jan Manek's PRELIMINARY update
IOTA/IOTA-ES occultation update for
(420) Bertholda / TYC 5757-00353-1 = SAO 144929 on August 26/27, 2003
visible from N Russia, SE Estonia, Latvia, Lithuania, NW Poland, NW Czechia,
Germany, NW Switzerland, France, NW Spain and N Portugal
Summary
In the night of August 26/27, 2003 a bright 8.6 mag star TYC 5757-00353-1 = SAO 144929
will be occulted by a 146 km asteroid (420) Bertholda. This update is based on
USNO/Flagstaff astrometry for the asteroid and UCAC2-beta star position.
The updated path shows ~3 path width north shift with time ~1.0 minutes later compared to
Edwin Goffin's nominal prediction
or ~2.5 path width north and 0.4 minutes later compared to Eric Frappa's prediction.
Updated path runs due to north shift over N Russia ~21:42 UT with St.Petersburg on north limit, SE Estonia ~21:42.5 UT,
Latvia ~21:42.5 UT, Lithuania ~21:42.6, NW Poland around 21:43.1 UT with Poznan in path, NW Czechia ~21:43.7 UT,
Germany from NE to SW around 21:43.9 UT with Berlin in path close to north limit, NW Switzerland ~21:44.4 UT,
France from NE to SW around 21:44.8 with Strasbourg, Dijon and Bordeaux in path, NW Spain ~21:45.8 and N Portugal ~21:46.1 UT with Porto in path.
Within uncertainty are many other places of this fine occultation. Refinement can be expected before the event, when new FASTT data will be available.
Please check the path chart for details.
Clear sky and good luck !!!

!!! 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 13.0
* labeled stars have indicated SAO numbers
* remarks: Detailed chart shows 30' blowup to show correctly the star in field.
40 degrees wide field chart is for orientation.

Jan Manek's 1st normal update
IOTA/IOTA-ES occultation update for
(420) Bertholda / TYC 5757-00353-1 = SAO 144929 on August 26/27, 2003
visible from N Russia, SE Estonia, Latvia, Lithuania, NW Poland, NW Czechia,
Germany, NW Switzerland, France, NW Spain and N Portugal
Summary
In the night of August 26/27, 2003 a bright 8.6 mag star TYC 5757-00353-1 = SAO 144929
will be occulted by a 146 km asteroid (420) Bertholda. This update is based on
USNO/Flagstaff astrometry for the asteroid and UCAC2-beta star position.
The updated path shows ~3 path width north shift with time ~0.9 minutes later compared to
Edwin Goffin's nominal prediction
or ~2.5 path width north and 0.3 minutes later compared to Eric Frappa's prediction.
Updated path runs due to north shift over N Russia ~21:42 UT with St.Petersburg on north limit, SE Estonia ~21:42.4 UT,
Latvia ~21:42.4 UT, Lithuania ~21:42.5, NW Poland around 21:43.0 UT with Poznan in path, NW Czechia ~21:43.6 UT,
Germany from NE to SW around 21:43.8 UT with Berlin in path close to north limit, NW Switzerland ~21:44.3 UT,
France from NE to SW around 21:44.7 with Strasbourg, Dijon and Bordeaux in path, NW Spain ~21:45.7 and N Portugal ~21:46.0 UT with Porto in path.
Within uncertainty are many other places of this fine occultation. Still one more refinement can be expected before the event, when new FASTT
data will be available and possibly also final UCAC2 data will be available.
Please check the path chart for details.
Clear sky and good luck !!!
The event at one glimpse:
* date and approx. UT time of event: August 26, 2003 @ 21:44 UT (Europe)
* magnitude of target star: 8.6
* magnitude drop [mag]: 5.0

* 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 5757-00353-1 = SAO 144929 = PPM 204597 = HD 199046
* constellation: Aquarius
* J2000 position [h,m,s; o,',"]: 20h 54m 47.4104s; -08o 10' 52.501"
* position source: recent UCAC2 beta

* B-V [mag]: +0.45
* remarks:
Target star is in west Aquarius, about 1.0 degrees NE of 4.7 mag star mu Aquarii = SAO 144895.
!!! 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 13.0
* labeled stars have indicated SAO numbers
* remarks: Detailed chart shows 30' blowup to show correctly the star in field.
40 degrees wide field chart is for orientation.

Jan Manek's 2nd normal update
IOTA/IOTA-ES occultation update for
(420) Bertholda / TYC 5757-00353-1 = SAO 144929 on August 26/27, 2003
visible from N Russia, SE Estonia, Latvia, Lithuania, NW Poland, NW Czechia,
Germany, NW Switzerland, France, NW Spain and N Portugal
Summary
In the night of August 26/27, 2003 a bright 8.6 mag star TYC 5757-00353-1 = SAO 144929
will be occulted by a 146 km asteroid (420) Bertholda. This update is based on
USNO/Flagstaff astrometry for the asteroid and UCAC2-beta star position.
The updated path shows ~2.5 path width north shift with time ~0.9 minutes later compared to
Edwin Goffin's nominal prediction
or ~2 path width north and 0.3 minutes later compared to Eric Frappa's prediction.
Updated path runs due to north shift over N Russia ~21:42 UT with St.Petersburg just north of north limit, very SE Estonia ~21:42.4 UT,
Latvia ~21:42.4 UT, Lithuania ~21:42.5, NW Poland around 21:43.0 UT with Poznan and Wroclaw in path, NW Czechia ~21:43.6 UT with Prague and Pilsen in path,
Germany from NE to SW around 21:43.8 UT with Berlin just north of north limit, NW Switzerland ~21:44.3 UT with Bern and Zurich in path,
France from NE to SW around 21:44.7 UT with Strasbourg, Dijon and Bordeaux in path, NW Spain ~21:45.7 UT and N Portugal ~21:46.0 UT with Porto in path.
Within uncertainty are many other places of this fine occultation. Steve Preston's path from July 18th update is still about 0.3 path widths more to SE.
Please check the path chart for details.
Clear sky and good luck !!!

* estimated maximum duration [s]: 11.9
* path description: given above
* Goffin's original chart reference: A03_0829
The occultation path:
* approximate ground width [km]: 250
* uncertainty [path widths]: 0.6
* uncertainty in time [s]: 8
* 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 5757-00353-1 = SAO 144929 = PPM 204597 = HD 199046
* constellation: Aquarius
* J2000 position [h,m,s; o,',"]: 20h 54m 47.4104s; -08o 10' 52.501"
* position source: recent UCAC2 beta
* estimated accuracy ["]: 0.02" (0.01", 0.01")
* V mag [mag]: 8.63
* B-V [mag]: +0.45
* remarks:
Target star is in west Aquarius, about 1.0 degrees NE of 4.7 mag star mu Aquarii = SAO 144895.
!!! 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 13.0
* labeled stars have indicated SAO numbers
* remarks: Detailed chart shows 30' blowup to show correctly the star in field.
40 degrees wide field chart is for orientation.
Data for the minor planet:
* general information:
number, name: (420) Bertholda
approx. diameter [km]: 146
* orbital information
orbit source: calculation Manek
source of used astrometry: USNO/Flagstaff (Ron Stone), La Silla (Raoul Behrend)
number of used observations: 143 USNO, 3 La Silla, 1 Japan
number of rejected observations: 18 USNO
time covered by the observations: 1998 08 26 - 2003 08 06
rms residuals ["] (RA,DE): 0.08", 0.09"
estimated positional accuracy at epoch of event ["]: 0.045", 0.045"
remarks: The single Japan position is derived from positive occultation by Bertolda on July 31, 2003.
Data for the event:
