Westward drift? Antarctic Circumpolar Current flows west to east.

Thank you Mitch, I meant the drift west to east, of course. Got it fixed.
It is too late just to be concerned about Climate Change

~3-4 km between yesterday's and today's shot.

A68A moving further east. Rotation seems to have stopped.

(Oops forgot the timestamps. The iceburg is moving to the right.)

5km eastwards movement between yesterday's and today's picture.

Yesterday's pic is the one where the iceburg is further to the left.

Here is A68A from 07th to 11th.

Slowly marching eastwards. In the last frame, you can see a) fast ice detachment and b) pivoting counterclockwise.

A68A from the end of October to today, daily increments, fast-playing to obscure the clouds.

So is it fair to say that it is now past any danger of grounding and is basically in the open sea?

I wouldn't say that quite yet. Perhaps there are more underwater mountains in its way.

I think this one makes it clearer with what i mean with 'underwater mountains in its way'.

This is the NASA Marple layer and yesterday's SNPP Day&Night band.

A68-A recently passed through 300 meters deep water without issues, only running aground at about 200 meters deep.  I don't think that 600 meter deep water will present a problem.

I think at this stage it's safe from grounding.
Blumenkraft thanks for the animations.

Very welcome, Oren.

But i disagree, somewhere out there it could get stranded IMHO. I base this assumption on a) there are more underwater mountains, no matter which way it takes (despite south of course, but i don't think it's headed south) and b) possibly inaccurate bathymetry maps. ;)

At depths yes, but a shallow that could be a hazard to shipping or snag a fishing net will be on every chart and has been for ages.

OK, that's a good point, Baking.

Well, if A68-A, per the attached tracking map of icebergs released from Antarctica, goes north or northeast it could get grounded.  (There are rock islands along the extension of the Antarctic Peninsula - the submarine ridge - the last being the South Orkney Islands.) Many of the tracked icebergs have wandered in these occasionally shallow waters.

New location:  The Antarctic Iceberg Tracking Database (https://www.scp.byu.edu/data/iceberg/ ) shows where icebergs have traveled.
Arctic ice is healthy for children and other living things.

That's a most useful map, Tor. Thanks for posting.

Here is A68A from 15th to today plus bathymetry.

It is clearly snaking along this underwater mountain. Shallow waters ahead.
