Exactly one year ago, I had posted about this round object found by sonar outside Sweden in the bottom of the Baltic Sea.
Now we have pictures and a video from a research team:    
The bad news is that it is definitely not a UFO. The good news is that it appears man-made, a kind of circular structure built with rounded limestone. 
Samples where taken and I imagine sometime in the near future we’ll know more.   
In the meantime check out the video below.
