Saturn Image Information
- Date: 2003.12.29 23:33 PST
- South pole is at the top
- This image was taken when Saturn was two days from opposition on 2003.12.31. As a result the planet shadow on the rings is in directly behind the planet as seen from our view point on Earth.
See Saturn 2003-2004 Opposition on how the shadow has moved since September.
- This is my first image to see four cloud bands on Saturn.
- The planet is showing through the Cassini division at the bottom the image.
