Some raws from 9th June appeared today (NAC ring images) which were taken during periapse last week.
See here. There are data missing from this batch of raws represented by horizontal gaps/lines in the images - does anyone know what causes this intermittent problem? (the lines have appeared on a small percentage of earlier images) Is it a software issue, or camera scanning, or data recorder issues, or problems with DSN reception of the data?? These have appeared later than they normally would, which would seem to indicate a problem getting them down - just curious..... |

Usually these are caused by DSN data dropouts or errors in transmitting the data from DSN to JPL. These images are tagged as preliminary in the hope that those gaps will be filled by more data coming down the pipeline, either from the DSN or by another pass through the Cassini SSR (though the latter is only done for high priority data). After a week, if those prelim images haven't been fixed, they are changed to final images, which allows their release on the JPL raw images page.

Thanks VP for that very clear explanation.
Had these been near-encounter Enceladus images then (for example), the likelihood is that the contents of the SSR would have been re-transmitted on another DSN pass. |

The analysis of these unusual images may help to determine vertical structure of Saturn's clouds. High clouds are clearly visible on Saturn's nightside

Are those 'blobs' like thunderheads sticking up above the dark hemisphere, or are we seeing buoyant gas balls off the limb ??
Freaky strange pictures either way. Doesn't look like comparable Voyager Neptune shot at all. |

Perhaps these are slightly higher clouds that catch the light better as we progress across the terminator? This type of thing would happen with high cirrus or cumulonimbus clouds on earth in twilight.

Is there some way to "automatically" grab a series of sequential images from the RAW JPEG web site ?
I use IDL.... not sure if I can do it from inside IDL.... I've been told it's possible using JAVA ... but I'm totally Java Handicapped <G> T |

No new images from Cassini on the website since September 20 (A few from August posted since). I assume the problem is with the Cassini website and not the space craft. Anyone know what's up? We have the next Enceladus in 12 days.

There has been at least one downlink since conjunction (probably more). Perhaps the webmaster is on holiday???
