B17-b (Ap)

A pair of weeks ago, initially, a huge iceberg and then many smaller ones, were spotted around Macquarie Island, an island midway between Australia, New Zealand and Antarctica, where icebergs are a very rare sight, as I reported in the this post:

Last week, icebergs has been seen even from the southern tip of New Zealand which is an even rarer sight and then, in a crescendo of breaking news a really enormous one, identified by scientist with the name B17-b has been detected on its way to Australia. The city-sized iceberg is now breaking up into hundreds of smaller icebergs as it drifts into warmer waters. This is creating potentially hazardous conditions for ships trying to navigate the region. The iceberg, was spotted last week on satellite imaging about 1,100 miles (1,700 kilometers) off Western Australia state, prompting New Zealand and than Australia's Bureau of Meteorology to issue a shipping alert. When first observed, B17B was a whopping 140 square kilometers (54 square miles). Now, it is about 115 square kilometers (44 square miles), or around 18 kilometers (11 miles) long and 8 kilometers (5 miles) wide.

The position of B17-b first sight:

Currently, B17-b journey to Australia is controlled carefully due to the danger that it represents.
These are three NASA satellite images of B17-b:

    This is really sad because it's the most incredible fact how our polos are smelting little by little that's terrible because we can get a awful flood one day in our planet.
