      I found this site (U.S. National Ice Center)
      https://usicecenter.gov/Products/AntarcIcebergs
      but i don't see "operational" data.

        A68a iceberg has started pivoting and heading now SE. As said above, the eastern route is not free of obstacles like Sandwich Islands and rocky shoals.

          ... today, I see, the mother berg doubled
          birthing a large child berg (aprox. 20 km long)

            Yes, this morning it was not so clear due to cloud, but right now it is obvious that a small part (however 20km long) has been separated from A68a.

                https://usicecenter.gov/PressRelease/IcebergA68E_F
                and
                https://modis.gsfc.nasa.gov/gallery/individual.php?db_date=2020-12-23
                Looks like a giant crack.
                During these breakup events a lot of energy released.
                The noises as the iceberg broke apart,
                called "icequakes" (or cryoseisms).

                I want to mention, also, that the "main" iceberg travells faster
                than the small fragment (35 nm north)

                    It seems that the big piece now moves to NW and the smaller ones to NE. May be due to a different depth and so reaching different current layers?

                      ...or maybe because of the divergence of the sea currents
                      in the area aprox. 90 NM south of the S. Georgia island.

                        Finally the iceberg stopped travelling and broke into several pieces.

                            Interesting, it shows how these huge icebergs are born.
