I've seen something similar, although less dramatic from a Scottish
steel production facility. It was a long time ago, but I think it was
related the a stage in the Bessemer process when either the converter
was opened, or emptied.

Does Ekateringburg have a foundry, or steel industry? If so, the locals
would surely have seen this before, but maybe not under such favourable
low-cloud Moon-less dark sky conditions.

Best wishes,
