We observed CO $J =$ 1-0 and HCN $J =$ 1-0 line emission toward a high-velocity, compact molecular cloud, CO0.02-0.02, near the center of our Galaxy, using the Nobeyama Millimeter Array (NMA). A CO velocity-integrated map with a resolution of 4.3”$\times$2.4” shows two oval clumps with sizes of 0.8pc. These clumps are seperated by 1.2pc, being located at the eastern and southwestern peripheries of...
