Molecular observations at 20 arcsec resolution of a small globule with bright rims in the IC 1396 H II region with the IRAM 30-meter telescope reveal a bipolar outflow associated with an IRAS point source. This indicates that star formation is taking place even in the lowest-mass Bok globules. CCD H-alpha, I, R and S II imaging of the globule's bright rim show the presence of an H II region and an optical counterpart of the infrared source. The outer layers of the globule are currently being evaporated by the UV radiation field of a neighbor O6 star, while the star formation is possibly induced by the shock front associated with the H II region.
