Scientific paper

UVBRI photoelectric sequences for fifteen AGNs were obtained with 0.6, 0.9, and 1-m telescopes. The data include 473 observations for 118 stars, giving an average of 4.0 observations per star, and 7.9 stars per sequence. Tables are presented of the fields observed, the magnitudes and colors of the sequence stars, and the mean differences between the results and those of other studies.
