Abstract
The infrared dark cloud G359.94+0.17 is a conspicuous, opaque cloud, which is seen in silhouette against the Galactic center. We found unexpectedly strong (&tilde 50 Jy) maser emission of CH
3
OH at 44 GHz with additional weak 22 GHz H
2
O maser and 43 GHz SiO thermal emissions toward this cloud. Detections of these molecular lines indicate that strong star-forming activities are proceeding in this cloud, which was not reported previously despite of numerous studies toward the Galactic center. The line profiles of the NH
3
inversion lines at 23 GHz indicate that G359.94+0.17 is composed of mainly two clouds with V
1sr
= 0, and 15 km s
-1
overlapped on the line of sight. The maser emission is associated with the 15 km s
-1
cloud, suggesting that it is located at the Norma spiral arm. eprintid:
