HD965 is a strongly magnetic peculiar A star with clear Zeeman splitting in its spectral lines, a rotation period greater than 2 yr, H-line core-wing anomaly, and strongly negative Stroemgren δc₁ and δm₁ indices. All of these characteristics are typical of the rapidly oscillating Ap stars, and it has been suggested that HD965 should be one. We have tested this star for photometric variability under excellent conditions with low scintillation noise using the 2-m TBL for 2.7hr at Pic du Midi Observatory. The amplitude spectrum of the light curve is flat with noise peaks below 0.2mmag in the frequency range of the roAp stars. This suggests that it is a non-oscillating Ap star, although proof of that will need further observations each year for many years, to rule out the possibility that rotational modulation has suppressed the observed amplitude in 2002.
