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.

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
