UFO over Sofia, Bulgaria July 6, 2023, UFO Sighting News.

Eyewitness states: There was so thunderstorm approaching in the beginning of July, right across my window. I was hoping to film a lightning with my phone slow motion camera. I grabbed my portable phone stand, put it on the table and star shooting. Unfortunately no lightning was captured, but after I reviewed the videos I found that one of the videos has a strange dark object moving around 500 meters from left to the right.
