A strange, S-shaped formation appeared on radar images taken off the West Australian coast on Feb. 12.
The anomaly, being called the "Rottnest Monster" because of its close proximity to that coastal island, has perplexed weather scientists who admit it's too large to be a ship and too strangely shaped to be a cloud.
So, what is it?
"There's no cloud, there's nothing to produce a rain echo, which we do see a lot, but not this particular shape," said weather bureau chief Neil Bennett. "They don't take on S shapes and things like that."
The weird radar image was checked against other Australian Bureau of Meteorology instrument readings in the area at the time, but experts have not yet concluded what is causing the unusual pattern.
Military authorities in the region have not weighed in on what may have caused the strange phenomenon and, so far, have made no official announcement or determination.
That didn't stop local amateur meteorologists to name the formation, and to tweet radar images out to Twitter, calling for other experts to explain what the weird image may have been caused by.
"Nice that our pet #RottNessMonster has avoided the shark baits. Her name is Susan & she likes to eat plankton," tweeted the Weather WA group.
The strange news comes in the wake of speculative reports, asking whether the Loch Ness Monster has died, since there have been no sightings, real or imagined, of the legendary Cryptid, in the Scottish lake for the last 18 months.
Some alternate theories have been proposed, but, so far, none of them can explain the radar anomaly, of a type possibly never seen before.
What do you think? Is there a natural explanation?
