Abstract: We present Cousins BVRI magnitudes for stars in the M 67 `dipper asterism' region, based on observations carried out at the prime focus of the 2.3 m Vainu Bappu Telescope of the Vainu Bappu Observatory, Kavalur. The photometric system is calibrated using the photometric standards in the field and linear transformation relations are derived. Photometric results are reported for 37 stars in BVRI bands. Results are also presented for an additional set of 35 stars in only two or three of these bands. The photometric accuracy is better than 3% for magnitudes B<16, V,R<17 and I<14, and is slightly poorer for the results presented beyond this limit.
