CCD monitoring of quasars and BL Lacertae objects

Johnson B CCD photometry of quasars and other active nuclei were obtained with the 1-m and 2.5-m reflectors of the Roque de los Muchachos Observatory in the Canary Islands between 1986 and 1987. Data are presented for PKS 1538+149, 3C 345, 3C 351, and BL Lac. Error sources are discussed, and it is noted that at least part of the error is due to uncertainties in the magnitudes of the observed sequence stars. 19 references.
