We have identified a spiral arm lying beyond the Outer Arm in the first Galactic quadrant ~15 kpc from the Galactic center. After tracing the arm in existing 21 cm surveys, we searched for molecular gas using the CfA 1.2 m telescope and detected CO at 10 of 220 positions. The detections are distributed along the arm from l = 13°, v = –21 km s–1 to l = 55°, v = –84 km s–1 and coincide with most of the main H I concentrations. One of the detections was fully mapped to reveal a large molecular… CONTINUE READING
