Differential Strömgren 
observations from the Four College
Automated Photoelectric Telescope (FCAPT) are presented for the CP stars HR 149
and HR 7911 and the mCP stars HD 32966 and HD 171782. The Mercury-Manganese
star HR 149 is found to be constant while HR 7911 with a period of 5.9617 days
probably has a component which is a magnetic CP star. Improved
periods were derived for HD 32966 and HD 171782 of 3.0927 and 4.4674 days,
respectively. The former is a rather large amplitude mCP star. Both have at
least one light curve different in shape from the others observed.
Key words: stars: chemically peculiar / stars: individual: HR 149 / stars: individual: HD 32966 / stars: individual: HD 171782 / stars: individual: HR 7911
