The MODIS on the Terra satellite captured this image of Icebergs B15F and B15K off the Princess Martha Coast of Antarctica on January 5, 2010. The icebergs are a little bit difficult to pick out of the sea ice and snow, but B15K is the long thin sliver near the center of the image. It's nearly parallel to shore. B15F is shorter and a little wider and slightly to the northwest of B15K. These icebergs have shifted quite a bit in the last few weeks.
This image shows the positions of the icebergs on December 21, 2009. B15K has rotated since then, and B15F has moved westward around the head of land, and then south to near B15K.
According to this blog B15K is about "the distance from Johannesburg to Pretoria" in length, which translates to roughly 60 km (37 miles).
