Pretty picture: High-res color view of Prometheus and the F ring

This week has been very heavy on text and light on pretty pictures. Next week will be more of the same. So I'm closing the week with a pretty picture, Cassini's best view of the inner F ring shepherd Prometheus.

Prometheus
Cassini captured the three images for this true-color view of the inner F-ring shepherd Prometheus on December 27, 2009. This view was composed of archive data by Gordan Ugarkovic. Prometheus is 119 × 87 × 61 kilometers in diameter.
This picture signifies some welcome news: the October 1, 2010 Cassini ISS, RADAR, and VIMS data release is out and accessible via the Imaging Node, covering the period from October 1 to December 31, 2009. Amateur image processors, have at the data! I'll wait to take a close look until it hits the OPUS search tool at the Rings Node.
