sunshine cloud - hazy liquid

Private swap from Russia.
The postcrosser tells me she lives where the first nuclear power plant was built which currently is closed and is a museum of nuclear industry, in Obninsk.
The postcard came with a spanish sticker (with a bull) and a happy postcrossing ink seal. ^_^

I have no idea what the words in cyrillic say on the postcard image, any tumlrer is willing to let me know?
Pretty please, tell me on my ask.
