The Bok globule Orion-I-2 was mapped in the lines of C-12O, C-13O, CO-18, CS, and HCN using the IRAM 30-m radio telescope. Observations revealed that there is a bipolar outflow extending over 40 arcsec associated with an IRAS point source of L(FIR) about 12 solar luminosities. It is concluded that low-mass star formation can take place in isolated and small Bok globules. The globule's core mass is 4 solar masses, the mass of the outflowing gas is 0.15 solar masses, and the total mass of the globule is about 14 solar masses.
