Abstract

We report VLA observations of H76α emission from the H II region in M-0.13-0.08, the Sgr A “15 km s-1 cloud.” The line to continuum flux ratio implies an electron temperature T e ~ 7500 K, slightly lower than measurements of T e in Sgr B2. The deduced number of early stars and the infrared luminosity are consistent with a normal IMF in this cloud.
