I discuss single-channel differential observations of late B and early A supergiants and AGB S stars obtained with the Four College Automated Photoelectric Telescope. The suggestion of periods longer than several years often seen in the seasonal mean magnitudes of both kinds of stars requires confirmation. I used Program Period98 to derive the most important frequencies for Deneb and for three AGB S stars.
