We present HST observations of the galactic center region using the Planetary Camera with the F1042M filter at an effective wavelength of 1.02 micron. We detect several infrared sources seen at this wavelength before but with angular resolution better than previous observations. Our data reveal the source GZ A which was first seen by Rosa et al. (1992) at 1 micron. However, our astrometry identifies this source as IRS 16C, not Sgr A*. We marginally detect an object at 2- to 3-sigma, coincident with the position of Sgr A* to within 0.2 arcsec. This object has unphysical continuum colors which are bluer than an infinite temperature blackbody. If the source is real and associated with Sgr A*, 1 micron line emission is a possible explanation. The possibility of this object being a foreground star or an HST artifact cannot be ruled out.
