Well, there is hope for the 5 July-August and the 5 after August voters!  Somebody will have guessed right.  GIF of the crack area:  June 16, 2020 and July 27, 2020.  One image was shifted to remove most ice tongue movement.  The cracks on the left and right have all widened during this 41 day period.  There is a hint of extension, too.  (But I "see" things that might not be there!)  Images from Sentinelhub Playground - dates are in upper left corner.  [needs a click to run]
Arctic ice is healthy for children and other living things.

The lateral rifts are extending/widening, but no cross-tongue connection is apparent, yet.  Some of the apparent extensions are hinted at in the June image (image adjusted to remove glacier movement) that are quite apparent in August.  Some of what I think are rifts may be valleys ( :-[), but I tried not to get carried away with 'seeing things'.  [Did you see the UFO last night??  :o] Tongue-end image for reference, and June & August GIF.  (click to run GIF)

We have no new ice island but we do have 5 winners (well, they will be winners, someday).  You may collect your prizes, lumps of Petermann Glacier ice suitable for cooling ice tea, up north.  (Just make you way onto Petermann Glacier at your own expense and risk.)  A substitute prize may be obtained from the freezer section of your refrigerator.  A screen print of the poll with "after August 2020" highlighted may impress your friends.

As of September 2, Sentinel Playground-hub image shows: no apparent change from 10 days ago. (click to enlarge)

I really tried, but my imagination went only as far as August 2020.

Well.  Do you see what I see? It looks almost like a complete crack, but not quite.  Worth keeping an eye on, for sure...

Some day's Polar View image look 'better' than others.  Probably still wishful thinking on my part.
