The giant iceberg known as A-68 that was produced in the Antarctic last week continues to drift seaward.
All the latest satellite images indicate the gap between the 6,000-sq-km block and the floating Larsen C Ice Shelf from which it calved is widening.
The particular image on this page was acquired by the Deimos-1 satellite.
It is not easy getting pictures of the Antarctic at this time of year because of the long winter nights and because of cloud cover.
Those spacecraft that have so far spied the berg have been relying on radar or on infrared sensors to pierce these difficulties.
The monster berg - which is a quarter the size of Wales, and one of the biggest ever recorded - is so far behaving as expected.
Theory suggests it should move, in the first instance, down the slope in the ocean surface that has been created by winds in the Weddell Sea pushing water up against the coast. But the leftward deflecting effect of the Coriolis force, produced by the Earth's rotation, should keep the berg relatively close to the continent's edge.
Interestingly in the Deimos image, acquired on Friday, it appears as though a large segment of "fast ice" that was attached to the berg has broken free. This fast ice is considerably thinner than the main block - a few metres thick versus the 200-plus-metres of the berg itself.
Polar research agencies are already discussing the scientific opportunities afforded by the breakaway.
Scientists will want to understand what effect the calving might have on the remaining parts of the ice shelf. Ten percent of Larsen C's area was removed by the departing berg, and this loss could change the way stress is configured and managed across the shelf.
There are numerous cracks just north of a pinning point known as the Gipps Ice Rise. These fissures have long remained static, held in place by a band of soft, malleable ice.
Researchers will want to check the departure of A-68 will not alter the status of these cracks.
There are also some fascinating investigations to be done on the seafloor that will soon be uncovered when the berg moves completely clear of the shelf. Previous big calvings have led to the discovery of new species.
