[10.07] Limits on inclinations in Saturn's rings

A. S. Bosh (Boston Univ. & Lowell Obs.)

In 1995, Saturn occulted the star GSC5249-01240 (Bosh & McDonald 1992); this event occurred when Saturn was in the ring-plane crossing season as viewed from Earth. The data from this event are unusually sensitive to out-of-plane excursions due to the almost edge-on aspect of this event. Previous analyses have shown the F ring to have a significant inclination of 0.0065 deg, or 15 km maximum out-of-plane extent (Bosh et al. 2002). Initial investigation of the remainder of the data set showed that several other features may be inclined as well, e.g. the Titan, Maxwell, and 1.470 Rs ringlets. Results of further analysis of these data will be presented. Support for this work (proposal #HST-AR-08761.01) was provided by NASA through a grant from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.
