Scientific paper

The photoelectric BVR photometry of eight weak-line T Tauri stars that was performed during 1992-1995 is presented. All of the stars exhibit periodic light variations attributable to cool photospheric spots. The photometric periods range from 0.7 to 10 days. For all these stars, the positions are shown in the two-color B-V, V-R diagram. Changes in the amplitude and shape of the folded light curves are discussed.
