Scientific paper

Optical region spectrophotometry of λλ3300-7530 is presented for three magnetic peculiar A stars, which exhibit definite λ 4200 and λ 5200 broad, continuum features, HD 32633, HD 34452, and HD 133029. The synthesized u-b and b-y colors vary in good qualitative agreement with published photometry and are consistent with the period of Preston and Stepien for HD 32633, of Deutsch for HD 34452, and of Bonsack for HD 133029. HD 32633 is reddened, HD 34452 shows a very sharp core to its λ 5200 feature, and HD 133029 exhibits complicated changes in its energy distribution.
