[59.04] Interstellar extinction in the MBM 12 molecular cloud area in Aries

Magnitudes and color indices of 140 stars down to V = 15 mag in the seven-color Vilnius photometric system are determined with a CCD camera in the area of the Aries molecular cloud MBM 12. Spectral types, interstellar color excesses and extinctions and distances of the stars are determined from the photometric data. We conclude that the extinction starts to rise at 140-160 pc, i. e., at the distance of the Taurus dark cloud complex. The distance of the MBM 12 molecular cloud is discussed. Some new heavily reddened stars and T Tauri stars are identified. The support by the AAS Chretien Grant of 2000 is acknowledged.
