Abstract:
Differential Stroemgren uvby 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 Hg-Mn 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.
