Abstract
We present optical and infrared photometry of stars near the MBM 12 dark cloud. The optical data indicate that there are about 40 candidate pre-main sequence stars in the same area currently occupied by eight bona-fide PMS stars. Analysis of 2MASS data suggests that 60% of PMS candidates have been detected. Some of these show evidence of optically thick disks. Our study of the 2MASS data also reveals a large enhancement of sources within the MBM 12 cloud, indicating that it is still actively forming stars.
