A 2.2-micron image of IRS 16, the relatively blue infrared source near the galactic center, is presented at the highest spatial resolution yet reported. It comprises several discrete, extended sources. By intercomparison of radio and infrared images of the region, the nonthermal radio source Sgr A-asterisk can be located relative to IRS 16 without the uncertainty of intermediate astrometric frames. No component of IRS 16 is coincident with Sgr A-asterisk. These data preclude the presence of a massive (greater than 10 to the 6th solar masses) black hole at the galactic center. Any black hole present has a mass nearer to 100 solar masses.
