This is a rare image of Janus (left) and Prometheus together with Dione, because of their closeness together and the level of detail. From what I've seen in the "imaging diary" it's been 6 years since Janus and Prometheus appeared in such detail together (search for pia08192), though both of them were imaged separately in higher detail in 2009 and 2010.
