Whither goest thou, iceberg?

 

A few posts ago I noted the observations of a really big iceberg that might possibly collide with South Georgia island in the far southern Atlantic Ocean.  Or maybe it's in the northern Southern Circumpolar Ocean.  

In any case, I used NASA's cool Worldview site to try and check on the progress of the iceberg since last I checked.  And it's definitely moving.   It is not necessarily moving much toward South Georgia at present, though.

What I did was measure the distance between the approximate centers of the two objects on November 21 and 26, then I kept the measurement line in place from the 21st and fast-forwarded to the 26th, but kept the measurement line from the 21st in place, so the movement can be perceived.  

Here's what it looked like on the 26th:











Here's the measurement of distance on the 21st (a very clear day -- remember, it's summer down there now):








And now here's the November 26th image again, but now with the November 21st measurement line.  Most of the iceberg's movement has been to the north, it seems, but that could change.  Or maybe it won't.  We can just keep watching.
