J/AJ/103/983        Stellar occultation candidates of Saturn       (Bosh+, 1992)

Stellar occultation candidates from the Guide Star Catalog. I. Saturn, 1991-1999 Bosh A.S., McDonald S.W. <Astron. J. 103, 983 (1992)> =1992AJ....103..983B (SIMBAD/NED Reference)
ADC_Keywords: Planets; Occultations Abstract: 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. File Summary:

Note (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. Note (2): t: Magnitude is approximately V. Note (3): S: occultation by Saturn R: occultation by its rings
