The above 120 second exposure with 0.8 arcsecond seeing was taken in the 890 nm
methane band using a narrow filter (5.0 nm FWHM). The exposure was begun at
about 4:06 Universal Time (UT) on November 22 (9:06 p.m. MST, November 21). A
central mask about 25 arcseconds wide is used to reduce the scattered light from the
disk of Saturn. North is to the top, and East is to the left. The Sun is on the opposite
side of the rings from the Earth, and so the rings are a `negative' image of their usual
appearance. The C Ring and Cassini's Division are bright while the A and B Rings are
dark. This image clearly shows the small Saturnian moons Epimetheus (top of the
East ansa, moving East), Prometheus (bottom of the East ansa, moving West), and
Janus (bottom of the West ansa, moving West). This image confirms the suggestion
from HST observations that Prometheus is about 30 minutes behind the position
predicted on the basis of the pre-1995 ephemeris.
New image of Saturn taken during the night of November 6, 1995.
This image was taken with the 1 meter telescope at Pic du Midi observatory
using an I filter. The observer was Francois COLAS member of the S2P
(Station de planetologie des Pyrenees).
Image taken by the Hubble Space Telescope on October 9, 1995 showing Saturn's
aurora.

Image by Jesus Rodriguez and Rafael Gonzalez & Francisco on October 12, 1995.
Image is dark-frame substracted (no flat-fielded) and post processed
with stretching, logaritmic scaling, unsharp masking and noise reduction.
Image best seen with gamma display around 2.0. Then, two satellites can be
seen as fuzzy points at each side of the disc.
