We have carried out 32 h of new time-resolved CCD UBV photometry of the high galactic latitude ? Cephei star HN Aqr. We detected its known single pulsation frequency and noticed additional variability at lower frequencies. It is not clear whether or not this longer-term variation originates from HN Aqr itself. The UBV colour amplitudes of the star's ? Cephei pulsation point towards an l=4 or l=2 mode, inconsistent with previous mode identifications.
