UBV photoelectric observations have been made of 642 stars in selected areas 92-115. The observing program was designed to provide new faint UBV standard stars on an internally consistent homogeneous system around the sky, easily accessible to large telescopes. These stars are nearly all within j 10 of the celestial equator. Of these stars, 335 have five or more observations. The majority of them are in the range 10." 5 < V < 12." 5. Sixteen Feige and Giclas stars have been observed some 20 times each in order to provide additional faint blue UBY standard stars.
