Roman managed to capture the rare phenomenon and although the footage is shaky the sphere of light is clearly visible.
During the recording as heard on the commentary:
Female: “What’s that over there?”
Roman: “Fireball lightning”
Male: “Look, look what is that?”
Roman: “Argh, it’s moving away. It’s the first time I see one in my life. It's going to move away. I lost it. Where it is? There it is. I wonder if it'll blow off soon. Yep, it blew off.”
Roman: “This is the first time in my life.”
Female: 'Horror, hide away from it.”
Roman Tregubov explained to the siberiantimes he had to stand on bricks to get a view of the ball lightning over a fence and bushes, which is why the footage is shaky.
