Unfortunately, I do not have photos from an earlier period than half a year. Maybe somebody has an older archive because polarview has no archives over a month.
ps.It seems to me that it is not yet an iceberg and it may take a long time before the second edge separates from the glacier. This rift, which has a size of 40km in the photo, started to be visible in the last half-year.-I wonder if this crack will continue to develop or the stress has been discharged.
