S. ; Gallagher, J. S. ; Hunter, D. A. Abstract CO emission has been detected in the irregular galaxy NGC 1569 using the 14 m telescope of the Five College Radio Astronomy Observatory. The central 1 kpc of this galaxy contains approximately 7,000,000 solar masses of H2 and 10,000,000 solar masses of H 1. Comparing NGC 1569 with the Scd galaxy IC 342, both of which are at roughly the same distance, the central regions have similar blue luminosities (about 2 billion solar luminosities), but NGC 1569 has a factor of 32 less CO. In order to form such a luminous region with a small supply of molecular gas, either the present burst of star formation in NGC 1569 must be very efficient and of short duration, or the atomic hydrogen in the outer part of the galaxy must be resupplying the central region.
