Rev: 145 Feb 10 - Mar 6 2011, Senkyo up-close for first time after the 'Arrow Storm' Options

From the Ciclops 'Looking Ahead' description for Rev 145: ... This will also be Cassini's first opportunity to observe up-close the region that was underneath the massive, "arrow" storm that was seen in September 2010. While this area has been seen at low resolution on at least two occasions since the storm, higher resolution observations are more useful for mapping the distribution of bright, intermediate, and dark albedo terrains in the south Senkyo region.

Would think the 3.3 deg fov of the WAC will be most useful camera to look at the region influenced by the 'arrow' storm, around 22hrs on the 18th as noted below. (unless the NAC can be 'pointed' to lower south latitudes and cover the area in higher res).

Keep in mind that for much of the flyby, the camera is not pointed at Titan as we are doing a CAPS/RSS observation and the HGA is pointed at Earth. Our first chance for looking at Titan occurs 14 hours after the flyby when we are 240,000 kilometers from Titan (1.4 km/pixel with NAC; 14 km/pixel with WAC). The best frames for looking at south Senkyo where something may or may not have happened in the recent past will be the last set from 350,000 kilometers (2.07 km/pixel with the NAC; 20.7 km/pixel with the WAC).

Thanks VP. Some NAC and WAC images from Feb 19th of Senkyo from approx 250 to 300 K km have now been posted on the raw image site. Not sure if the NAC images are blurred by spacecraft motion or atmospheric dispersion effects but they are a bit disappointing. Images rotated so N is up. Cropped NAC image N0016817 is on the left. Can't say these are definitive re showing changes related to the 'arrow' storm of T72.
