Summary
| Description |
English: The shadows of Saturn's rings appear as a narrow band on the planet in this image taken as Saturn approaches its August 2009 equinox. The novel illumination geometry that accompanies equinox lowers the sun's angle to the ring-plane and causes moons and out-of-plane structures to cast long shadows across the rings. These scenes are possible only during the few months before and after Saturn's equinox which occurs only once in about 15 Earth years. This view looks toward the unilluminated side of the rings from about 21 degrees above the ring-plane. |

The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of near-infra-red light centred at 918 nanometres. The view was acquired at a distance of approximately 620,000 kilometres from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 26 degrees. Image scale is 33 kilometres per pixel.
