Looks like Apple got the new versions of DS out just in time to fix the “where the frak is Comet Lulin?” bug. The comet passed right by Saturn last night. You can see a terrific photo of the two at http://www.spaceweather.com.
Lulin is now in Leo and traveling very fast each day. It peaked at about the predicted brightness, around 5th magnitude. Visible to the unaided eye-barely-in a dark sky. But should be a nice binocular object.
