I've added a couple more images to the GIF of A68A, roughly at 24 hour increments, the last just before midnight UTC.
Movement had been due North up until 24 hours ago when it shifted dramatically to the East, just short of the grounded smaller icebergs.
Is it just luck that it avoided grounding, or has it made contact with the sides of a much shallower rise and is sliding past? And if it is sliding, will the irregular sides of the iceberg eventually get hung up?
Edit: Also note the medium size berg (broken off from A68A) that has successfully maneuvered to the East of the grounded ice showing the shallow area is really quite small.
