You know your machine, but at 195 you're 15° cooler than I would have printed it. I'll assume PLA which isn't known for warping. It can warp if bed adhesion is weak, or if there is a draft from a heat register (or somewhere) blowing at the printer. I see the bed is at 60 and that's OK, are you using anything as an adhesion promoter (hairspray or glue stick)? Are you using a glass bed?
But yes, it could just be a fingerprint or something on the bed.

Could be a "greasy" (dirty) spot on the build plate.
