I think it would look like nothing unusual. You would be going about your business as usual then you might be lucky and see a blinding flash then nothing else for ever!
I don't think that Russia has any of its Tsar Bombas at the moment but Putin never tells me very much about what they have and what they don't have. They make the Hiroshima and Nagasaki bombs look like fireworks. Cities not just flattened but vapourised, damage to buildings 100 miles away and the flash can be seen 600 miles away.
