Bizarre Radar Map or UFO?

UFO or Radar Anomaly

Strange images appearing on radar maps from the Australian Government's Bureau of Meteorology have the Web wondering: What is it? (BOM)

They are the digital-age equivalent of crop circles -- mysterious patterns appearing on the Australian Bureau of Meteorology's national radar system without any explanation. UFOs, perhaps?

And the random images, described as red stars, rings of fire and white doughnuts, are sending online conspiracy Web sites into meltdown. The anomalies first began on January 15 when an "iced doughnut" appeared over Kalgoorlie in Western Australia.

Satellite imagery showed there was no cloud over the area at the time to explain the unusual phenomenon, but farmers' online comments claimed it was "unusually hot" all day. It was followed by a bizarre red star over Broome on January 22 and a sinister spiral burst over Melbourne described by amateur radar buffs as the Ring Of Fire Fault.

The Bureau, which did not respond to repeated requests for comment, has acknowledged the anomalies on its popular Web site. It has posted a disclaimer above the national loop feed putting the images down to "occasional interference to the radar data."

"If you notice any circular patterns or straight lines originating from the center of the radar location, this is due to occasional interference to the radar data. The Bureau is currently investigating ways to reduce these interferences." the disclaimer said.

Conspiracy Web sites, however, have lit up with dozens of breathless theories behind the strange anomalies from alien involvement, secret military testing to government weather modification. One theory gaining traction online is the belief the U.S. military has expanded its High Frequency Active Auroral Research Program.

Based at a remote research station in Alaska, the HAARP project involves shooting extremely high frequency radar bursts into the upper reaches of the atmosphere to see what happens after particles of the ionosphere are temporarily excited.
