Scientific paper

Broad-band, near-infrared (1.65 and 2.2 micron) observations of the central region of NGC 4151 have been made using the technique of one-dimensional speckle interferometry. The region is clearly separable into a spatially compact central component surrounded by an extended component of different spectral character. Extended component fluxes are found to be consistent with a stellar population of late-K and early-M giants. An upper limit of 174 milliarcsec is found for the angular spatial extent of the compact region.
