Residents in the Sverdlovsk region of Russia witnessed a huge fiery flash in the sky on 14 November 2014 around 6:39 pm local time. Thankfully the prevalence of dash cams meant there was plenty of amateur footage to capture the event. I’ve included a second video below for another view of the fiery phenomenon.
Many are speculating it was likely a bright fireball meteor although no official report has been released identifying the unknown object in the sky.
