Several northern Ap stars have been monitored to search for short-period (P less than 15 min) photometric variations. It was not possible to confirm the low-amplitude variability of HR 2977 and HR 5156 reported by Matthews and Wehlau (1985). HR 5747 was observed near magnetic maximum; it showed no sign of rapid variations. No evidence of variability was found in HD 165474, HD 188471, and HD 191742 over several days of observation. Of the seven Ap stars observed, only HR 7167 (10 Aql) showed evidence of rapid light variability, with a period of 11.4 minutes and a peak-to-peak B amplitude of about 0.55 mmag. This detection is considered only tentative; further observations are needed to confirm the variability of HR 7167.
