Photometric groups tained with the Four College Automated Photoelectric HD Number Star Name Type V Spectral Type Telescope shows that the hot HgMn star 33 Gem is pho- tometrically constant. The Si star HD 15980 is found to 15980 v 7.89 Ap Si be a variable whose period is significantly greater than 2 16219 HR 760 c 6.54 B5 V years. The unusual magnetic chemically peculiar Co star 16004 HR 746 ch 6.36 B9p HgMn HR 1094 is discovered to be a low amplitude photometric variable with the magnetic field period of Hill & Blake, 22316 HR 1094 v 6.30 B9p 2.9761 days. The ephemeris for the magnetic chemically 23383 HR 1147 c 6.10 B9 Vnn peculiar star HD 115708 of Wade et al. is confirmed with 23594 HR 1161 ch 6.46 A0 Vn the error in its period of 5.07622 days being greatly re- 21447 HR 1046 c 5.09 A1 V ch duced. The u, v, b,andylight curves for both HR 1094 20536 6.76 B8 IV and HD 115708 exhibit differences which indicate complex 49606 33 Gem v 5.85 B7 III HgMn elemental photospheric abundance distributions. -
