The solar system is a happening place this week! I just learned of a major storm in Saturn's northern hemisphere, being monitored by the usual band of talented amateurs. See this site for a list of recent images. Chris Go's site has a particularly nice image.

It's interesting to check earlier Cassini images to see if there are any images showing how this new feature formed. I imagine it might have started as a small, bright spot.
Unfortunately there do not seem to be many images of Saturns this month but I found these images from December 5: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=230356 http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=230355 A small, bright spot appears in both of the images so it is real. It's located at approximately the 'correct' latitude but I don't know if this is the same feature - this could be determined if I knew the subspacecraft longitude. I'm aware it's very difficult to change observations that were planned months in advance but this is a *really* interesting event. Hopefully there are enough Saturn observations planned for the next rev. I remember some quick changes to Galileo's observations in response to unexpected events, e.g. the loss of the E16 Europa imaging (some of the originally planned E16 observations were incorparated into the E17 observations) but I imagine the Cassini obervation sequences must be far more complex than Galileo's. |
