Sziasztok !

Akar valaki foglalkozni a targybeli kisbolygofedessel?
Nagyjabol hazank eszaki reszen varhato a fedes.
En probalkozni szeretnek csikhuzos felvetellel.

Ha valaki tud pontosabb adatokkal szolgalni szamomra,
azt nagyon szivesen vennem.

                     IOTA/IOTA-ES occultation update for
        (516) Amherstia / TYC 2309-00935-1 on November 19/20, 2000
     visible from Caucasus, S Ukraine, Moldova, N Romania, N Hungary,
          SW Slovakia, N Austria, S Germany and mid-north France

Summary

In the night of November 19/20, 2000 a 10.0 mag star TYC 2309-00935-1
SAO 55310 will be occulted by a 76 km asteroid (516) Amherstia. This
update is based on USNO/Flagstaff and TMO astrometry for the asteroid and
Tycho-2 star position.

The updated path shows ~6 path width north shift and time ~0.4 minutes
earlier compared to Edwin Goffin´s nominal prediction.

The path of this occultation runs over Caucasus ~0:29 UT, S Ukraine with
Crym and Odessa ~0:29.5 UT, Moldova ~0:29.4 UT, N Romania ~0:30 UT, N
Hungary ~0:30.3 UT, SW Slovakia ~0:30.4 UT, N Austria with Vienna ~0:30.6
UT, S Germany with Munich and Freiburg ~0:30.9 UT and mid-north France
south of Paris ~0:31.5 UT.

Good luck !
