Anticipation Builds as Equinox Draws Near

With equinox tantalizingly close, Saturn's rings are giving up more of their secrets. Obvious shadows seen in recent Cassini images have revealed a moonlet embedded in the outer B ring and shadow-casting structures rising above the F ring. (Image advisory can be found here.)

Aug 7, 2009: A Small Find near Equinox - The Cassini spacecraft captured this image of a small object in the outer portion of Saturn's B ring casting a shadow on the rings as Saturn approaches its August 2009 equinox.
Aug 7, 2009: Punching through the F Ring - This image, taken as Saturn approaches its August 2009 equinox, shows a shadow being cast by a narrow, vertically extended feature in the F ring.
Aug 7, 2009: Shadows in the F ring - Cassini spies a shadow being cast by a vertically extended structure or object in the F ring in this image taken as Saturn approaches its August 2009 equinox.
Aug 7, 2009: Shadow Reaches A Ring - The revelations of equinox continue as a vertically extended structure or object in Saturn's F ring casts a shadow long enough to reach the A ring in this Cassini image taken just days before planet's August 2009 equinox.

20tauri -- Equinox at Saturn began at 00:15 Universal Coordinated Time August 11. For people in the United States, that moment would still have been August 10 because of the difference in times zones.

I've seen both the 10th and 11th as dates for the equinox...is that just due to different time zones?

Only three more shopping days.
