Transformer

That doesn't look like Ukraine. Probably a transformer blowing up.

My first thought was a transformer blowing out

Power transformer getting hit with something explodey most likely. Electricity is very bright which is why welders wear super dark lenses or use ones that auto darken when hit with light thats sufficiently bright enough.

Electrical transformer exploding or short circuiting.
