User:Mistrz/przeciwsłonecznie

Regular adverb from przeciwsłoneczny.

Easily attestable through google, but websites aren't "durably archived"…

Not attestable through National Corpus of Polish(nkjp.pl) and Usenet has only one citation:

  • Lua error in Module:parameters at line 828: Parameter 2 is not used by this template.

Maybe later something will come up.
