J/AJ/103/983 J/AJ/103/983 Stellar occultation candidates of Saturn A S Bosh S W Mcdonald Astron. J. 103 983 1992 1992AJ....103..983B Occultations Solar system We present a list of 203 potential occultations by Saturn and its rings of stars from the Hubble Space Telescope Guide Star Catalog (GSC), during the years 1991-1999. Because the GSC is not a complete catalog, this is not an exhaustive list of Saturn occultations. In particular, stars brighter than magnitude 8 are not included. However, this list does include many fainter candidates than do current occultation candidate lists for Saturn; these fainter stars also can provide a high signal-to-noise ratio if observed with a large telescope or in the infrared where Saturn and its rings have absorption bands. We list the occultation circumstances, as well as star information found in the GSC.

GSC GSC star number --- Date Predicted date of closest approach "DD/MM/YY" UTh Predicted time of closest approach (hours) h UTm Predicted time of closest approach (min) min Dist Distance between the star and Saturn at closest approach arcsec n_Dist Note on distance number=1 * : These events are nominal hits. The star is within Saturn or its rings (as indicated in the last column) by less than 2.2arcseconds. **: These events are nominal misses. The star is outside Saturn or its rings by less than 2.2 arcseconds. --- PA Position angle deg Mag Magnitude mag n_Mag Note on magnitude number=2 t: Magnitude is approximately V. --- Vel Velocity km/s SunEl Solar elongation angle deg RAh Right ascension (J2000) h RAm Right ascension (J2000) min RAs Right ascension (J2000) s DE- Declination sign --- DEd Declination (J2000) deg DEm Declination (J2000) arcmin DEs Declination (J2000) arcsec Plate GSC plate number --- EastLong East longitude on Earth of the sub-Saturn point deg Event Type of event number=3 S: occultation by Saturn R: occultation by its rings --- James Marcout, Patricia Bauer CDS 1995Feb14 UNKNOWN UNKNOWN Keypunched at CDS * 14-Feb-1995: first archived at CDS * 15-May-1995: three errors corrected in table1 J_AJ_103_983.xml
