I see it, but based on the shape and scale of the other cracks and the bends in them, I don't believe it is anything other than just noise at this point.

I can see it, but only an animation (corrected for glacier movement) can "prove" if it's a crack and if it's new.

I've been 'seeing things' for a long time (and sometimes conflicting with 'each other'), but maybe today you'll see 'it' in this GIF made from yesterday's PolarView.  I see a trace of something (a crack?) the yellow line approximately follows .  [Click to play]   (Edit: approx. location of GIF in outline.  Petermann Fjord is 15 km wide.)

(I sure appreciate Thomas's GIFs too.)

At this point I belive it is only a UIO?
Have a ice day!

an Unidentified Identified Object?

No an Undentified Ice Object.

Further to what Thomas posted above concerning a crevasse on the NW side of the glacier, the mid-glacier crevasse has also widened over the course of a year.  Images are from Sentinel-hub Playground (April 2018 and April 2019).  The date bars are 150 meters wide and about 38 meters tall.  The location of the crevasse is near the bottom of the image in this post.

Different from the post above, these two SentinelHub Playground images are 28 days apart showing Petermann Glacier is moving about 3 meters per day (at this location).  The orange lines are in the dip of the mid-glacier stream valley on the April 14 and May 12 images.
