For now, it's an unidentified submerged object. But a strange circular formation deep below the Baltic Sea has sparked great excitement among UFO believers who think it might be a crashed flying saucer.
While searching for shipwrecks in the waters between Finland and Sweden on June 19, a Swedish team of nautical salvagers say they uncovered a "very strange anomaly" -- a round object about 60 feet across resting about 300 feet below sea level.
"You see a lot of weird stuff in this job, but during my 18 years as a professional I have never seen anything like this. The shape is completely round," Peter Lindberg, leader of The Ocean Explorer team, told the local press, according to MSNBC.
The circular object -- described by Gizmodo as resembling Star Wars' Millenium Falcon -- is also trailed on one side by what appears to be a lengthy patch of displaced seabed.
That has lead some UFO believer to surmise the strange circle is a wrecked UFO, which crashed onto the seafloor and left behind a path of destruction measuring some 900 feet, according to News.com.
The object could, of course, be a natural phenomena, or something manmade.
Without any assurance it was otherworldly, The Ocean Explorer team initially said it had no intention to pursue further investigation after publicizing the finding.
"It is not in our sphere of interest to go for this object since the cost for each hour out on the sea are tremendous," wrote Lindberg, whose company has made a name for itself by searching for "fluid gold" -- bottles of champagne, wine and liquor that can be retrieved from shipwrecks, with great profit.
"Since it might be nothing we can not afford spending funds just to have a look at it, even if it might be a 'new' Stonehenge standing on the bottom."
But thanks to international media coverage, interest from around the world and perhaps some donations, The Ocean Explorer team appears to have had a change of heart.

"We will go out again soon to document and film the object," reads a message on the website. "We have received many emails that people want to donate money to the project. We are very grateful for your donation."
On the Ocean Explorer Facebook page, where team members have already started advertising "Secrets Of The Sea 2011-12" shirts decorated with a picture of the round object on the seafloor for $20, Lindberg wrote the following message:
Ok folks here are some relevant information; We will equipe the ROV with a real time 3D-sonar so we can get really nice images at close range . . . [W]e will use a multibeam sonar and an ordinary side scan sonar. We will have divers with rebreather equipment with us but they will be sent down as a last option. We have also thought about geiger-equipment. But right now there is not enough funds so we can proceed, we working on it though
