Summary

[edit]
Description
English: This sequence of 100 sec exposures taken with HST's Wide Field and Planetary Camera (WFPC2) in planetary mode on 10 August 1995 shows the newly discovered object 1995S5 (red arrows) moving in its orbit around the planet. As it moves further from Saturn, its brightness decreases appreciably. This brightness variation is more consistent with that expected for an elongated, opaque clump of ring material than for a satellite, leading to the suspicion that 1995S5 is in fact a ring arc rather than a previously undiscovered satellite. It is likely that it lies within the narrow, braided F Ring.
