The CO J = 2-1 emission has been mapped for the first time at high spatial resolution in the central region of M82. The region of strong CO emission has an extent of 750 x 550 pc and has a radial velocity distribution which is centered about a mean systemic velocity of v/sub LSR/ = 220 km s/sup -1/ and which is in agreement with the (Ne II) rotation curve. anomalous emission is found at v/sub LSR/ = 170 km s/sup -1/ which is displaced by 250 pc (0.25) to the SW of the center of the CO emission and has a significant minor axis extension. This emission may be related to the compact radio source 41.9+58, the optical filaments, or possibly to the intergalactic gas cloud with which M82 is thought to be colliding.
