Its position is in the immediate vicinity of the new infrared source recently discovered by Kleinmann and Wright and very near the position of a strong timevarying H2O maser. Extended emission from HCN, SO, and millimeter H2CO has been detected. Emission lines of 22CO and 12C1 have been mapped throughout this region, and 12C1 has been detected in two locations. Results of the CO observations set a lower limit on the mass of this source of M> 6000 M0 and indicate that the cloud may be undergoing collapse.
