A Russian dash cam recorded a massive flash of light in the sky over Russia's Sverdlovsk region on November 14th, 2014. The flash was so bright it went from darkness to almost daylight in seconds.

In this second video around the 20 second mark it looks as if the source of the light may be on the ground in the distance somewhere.
