A strange, snake-like image appeared on weather radar in the ocean off the coast of Australia near Rottnest Island Wednesday, baffling meteorologists. Theories as to what could cause such a phenomenon swirled. But now the government is coming forward with an explanation.
Neil Bennett with Australia’s Bureau of Meteorology told ABC News he ruled out the S shape being caused by a cloud or rain echo.
“They don’t take on S shapes and things like that,” he said.
With meteorological causes debunked, some went as far to speculate that it could be a giant sea creature, dubbing it the “Rottnest Monster” or “Rottness Monster,” a play off of the Loch Ness monster.
So what is it?
Thursday a defense spokesman answered inquiries, saying the shape was caused by a training exercise that involved ships and aircraft, The Guardian reported.
The exercise was “designed to prepare a navy warship for an operations deployment,” the spokesman said, adding that “environmental conditions over the West Australian coast at the time of the activity provided a unique opportunity for this routine activity to be visible on the weather radar display.”
Some are saddened — albeit jokingly — that it wasn’t a sea monster.
Before the military officially came forward to note its involvement, some on Twitter pointed out that flight radar showed a Learjet flying over the area around the time the strange formation was spotted.
According to ABC News, the defense spokesman said the activity is ongoing.
