A U-B search to 21st magnitude in a 1°×1° region centered on the best position for the Korean nova of 1437 has revealed no unique candidate. Instead, we find 7 faint UV-bright stars with CV-like emission lines. The implied space density is two orders of magnitude higher than the classical space density for CV’s.
