It looks like one of early Ukrainian award badges, before the consolidation to all-Union awards. Looks like it refers to a specific event (in January 1918?)
Something tells me this is a modern made example. The Sun is goldplated but for a badge that is over 80 years old it seems to be in great shape! These rare badges are faked way too often.
