Seeing was good this evening. Transparency was better than yesterday. Tonight there is a double transit of Dione and Enceladus. It is interesting that Dione and Enceladus has a double transit every around 2.6 days.!! They are also aligned at almost the same plane. John Rogers,the venerable author of The Planet Jupiter,has suggested that Dione might be the cause of the "tiger stripe" fissures in Enceladus! That is really interesting as the frequent close encounter of Dione could create tidal effects in Enceladus.
In the animation below you can see Dione and it's shadow following this ice moon. Enceladus is more difficult to see but you can see a hint of it just north of the ring. There is a lot of band details.

Under average seeing,Saturn with its bright North equatorial spot which seems to spread in both longitude and latitude these last weeks,and which drift rate seems to slow down a bit:

Here are some images from March 18-19th under some excellent seeing. Various spots can be seen in the animation, with the bright Equatorial Zone storm being very prominent (this could be seen on the raw captures.) There is also a darkening at the ring ansae which is likely the Encke division. Other images from the 21st under very good conditions also show this (to be sent later.)
