    Plotting the R/B track for your location, it did pass quite
    close to theta-Cepheus (mag 4.21, HP #101093, HD #195725).
    The SkyMap-predicted magnitude was +4.3 at closest approach
    to the star, so I'd say that agrees quite closely with your
    observation.  (I used the Molczan standard magnitude of +5.5).
    Perhaps you were using a default standard magnitude of +6?
