B15A Causing problems again
Back on Dec. 16th I mentioned an iceberg that was terrorizing penquins and causing some difficulties for our Antarctic researchers.
Well, B15A is at it again, this time it's threatening a glacier (actually the ice tongue of a glacier) with catastrophic destruction.
Ok, Ok, I'm putting too much dramatic emphasis on this event. However, it's kinda cool to watch this huge iceberg running amok around down there wreaking havoc, terrorizing penquins and giving everyone what could prove to be a spectacular show, again and again. It seems that if the model holds true and the collision does occur it'll probably happen again and again, until B15A is obliterated.
Click the links above, watch the animated GIF's and marvel at the intricate Antarctic dance. The big .tif files at the bottom of the article are cool too.

And today, januari 16th, on the site you linked, NASA still says that experts expect a collission no later than the fifteenth. Nowhere on the internet any actual data can be found. Did the iceberg disappear?

January 18, and still no news anywhere. Very, very odd.

Daily satellite pictures!
It was expected the glacier would hit the Drygalski tongue, perhaps snapping it off.
Look at the movement between January 12, 13 and 14: B15A moved sideways, smashing a huge area of icy surface into hundreds of pieces, and was bouncing back away as the "frontal" collision was still being predicted. On Jan 17, B15A moved back to where it was on the 12th, and now seems to be rather immobile and waiting for the next push.
In the meantime, Jan 16, 17 and 18 show B15J (the "round" piece in B15A's axis on its lower right) wanting to go out for a swim.
