A fog bow is a similar phenomenon to a rainbow, however, as its name suggests, it appears as a bow in fog rather than rain.
Chernobyl...wow did not know this about the power plant
The "Bridge of Death". On April 26,1986, reactor 4 at Chernobyl failed. Some residents of Pripyat went to this bridge, where they could have a good look at the reactor. Some say it was the most beautiful thing they have ever seen in their life. Unfortunately the wind was blowing towards them, carrying a heavy dose of radioactivity with it. Almost everybody who stood on the bridge died within the next two days.
