Like an approaching UFO, the bright white luminous ball glides over a field, before heading into woodland.
A local caught on camera this unusual example of ball lightning near his
dacha (country house) outside Novosibirsk, Siberia's largest city. His grasp of his cell phone was shaky but his analysis of the phenomenon - as heard on the commentary - was accurate, say experts.
'What is it there?' a female voice asks from a distance.
'Fireball lightening,' answered the man with the mobile phone camera, Roman Tregubov, a graduate of the Novosibirsk State Technical University.
'Look, look, what is it?' another man asks.
'Argh it's moving away,' the cameraman says. 'This is fireball lightening, it's the first time I see one in my life. It's going to move away. Lost it. Where it is? There is it. I wonder if it'll blow off soon. Yep, it blew off.'
